论文标题A novel solid-state Li–O2 battery with an integrated electrolyte and cathode structure

作者X. B. Zhu, T. S. Zhao,* Z. H. Wei, P. Tan and G. Zhao

期刊名称Energy & Environmental Science

期卷8:2782-2790

简单介绍A high internal resistance and limited triple-phase boundaries are two critical issues that limit the performance of conventional solid-state Li–O2 batteries. In this work, we propose and fabricate a novel solid-state Li–O2 battery with an integrated electrolyte and cathode structure. This design allows a thin electrolyte layer (about 10% of that in conventional batteries) and a highly porous cathode (78% in porosity), both of which contribute to a significant reduction in the internal resistance, while increasing triple-phase boundaries. As a result, the battery outputs a discharge capacity as high as 14200 mA h gcarbonu00021 at 0.15 mA cmu00022, and can sustain 100 cycles at a fixed capacity of 1000 mA h gcarbonu00021. The novel integrated electrolyte and cathode structure represents a significant step toward the advancement of Li–O2 batteries


论文标题A high-rate and long cycle life solid-state lithium–air battery

作者X. B. Zhu, T. S. Zhao,* Z. H. Wei, P. Tan and L. An

期刊名称Energy & Environmental Science

期卷8:3745-3754

简单介绍Lithium–air batteries are currently limited to being operated under pure oxygen rather than ambient air, primarily due to the discharge product, lithium peroxide, reacting with water and carbon dioxide in ambient air to produce lithium carbonate, which renders the battery irreversible. A solution to this debilitating problem is to install an oxygen selective membrane that only allows oxygen to enter the battery. While theoretically sound, this method causes a significant decrease in the oxygen transfer rate due to a limited oxygen permeation area of the planar membrane and an increase in the oxygen transport distance from the membrane to the reaction sites. In this work, we create a novel solid-state lithium–air battery having a porous LATP cathode, designed using silicone-oil film coated pores that block water vapor and carbon dioxide from reaching reaction sites, but allow a high rate of oxygen transfer owing to an increase in the specific area of the films and a reduced oxygen transfer resistance. This battery can operate in ambient air at 5000 mA h gcarbonu00021 for 50 cycles (125 days). Moreover, the charge/discharge rate reaches as high as 2.0 mA cmu00022, a value which is about 40 times higher than that of conventional lithium–air batteries having an oxygen selective membrane external to the cathode.


论文标题A high-performance solid-state lithium-oxygen battery with a ceramic-carbon nanostructured electrode

作者Xingbao Zhu a,b, Tianshou Zhao a,n, Peng Tan a, Zhaohuan Wei a, Maochun Wu a

期刊名称Nano Energy

期卷26：565-576

简单介绍Ceramic lithium-oxygen batteries that use non-flammable and non-volatile electrolyte have the potentialto store a large amount of energy in a relatively safe way. However, the performance of this type ofbattery has been extremely low due primarily to the large ohmic-resistance from a thick electrolyte andthe limited triple-phase boundaries (TPBs) in conventional cathodes. In this work, we fabricate aseamless electrolyte-electrode structure by one-step sintering a rather thin Li1.3Al0.3Ti1.7(PO4)3 (LATP)electrolyte layer (20 mm thick) onto a porous LATP substrate. A hierarchical carbon is then grown in thepores of the porous LATP, uniquely forming three-dimensional pathways for the transport of lithiumions, electrons, and oxygen throughout the entire cathode. It is found that the cathodic TPBs are 330times larger than those of conventional solid-state lithium-oxygen batteries. As a result, the battery iscapable of operating in O2 for over 1174 cycles (u** days) and for over 450 cycles (75 days) withdegradation of o3% in ambient air when RuO2 and NiO are used as the catalysts. Moreover, the charge/discharge rate reaches as high as 15 mA cmu00032, 2–4 orders of magnitude higher than that of conventionallithium-oxygen batteries.


论文标题A nano-structured RuO2/NiO cathode enables the operation of non-aqueous lithium-air batteries in ambient air

作者P. Tan, Z.H. Wei, W. Shyy, T.S. Zhao* and X.B. Zhu

期刊名称Energy & Environmental Science

期卷9：1783-1793

简单介绍We report a cathode composed of RuO2nanoparticle-decorated NiO nanosheets for a non-aqueous lithium–air battery. Unlike most of the previously reported non-aqueous lithium–air batteries that are operated with pure oxygen only, we demonstrate that the present cathode enables the battery to be truly operated in ambient air at 500 mA h g611for 200 cycles (800 h), with stable coulombic efficiency (100%) and high energy efficiency (6575%). The stellar performance is attributed to the favorable combination of RuO2nanoparticles and NiO nanosheets, which not only catalyzes the oxygen reduction and evolution reactions, but also promotes the decomposition of the side products, including lithium hydroxide and carbonate formed from water and carbon dioxide in the air during discharge.


论文标题Ef？cient Electro-Catalysts for Enhancing Surface Activityand Stability of SOFC Cathodes

期刊名称Adv. Energy Mater

期卷3：1149-1154

简单介绍ABSTRACT The search for a sustainable supply of clean and economical energy has stimulated great interest in fuel cells for direct conversion of chemical fuels to electricity. Among all types of fuel cells, solid oxide fuel cells (SOFCs) are the cleanest and most effi cient ones with excellent fuel fl exibility. They are capable of direct utilization of a wide variety of fuels, from hydrogen to hydrocarbons, coal gas, and bio-derived fuels. [ 1-4 ] One of the technical hurdles to commercialization of SOFC technologies, however, is the high operating temperature that requires the use of expensive materials. [ 5-7 ] The enhancement of cathode activity represents a vital step toward successful reduction in operating temperature since the resistance to oxygen reduction reaction (ORR) contributes the most to energy loss in the existing SOFCs, more so at lower temperatures.


论文标题Hierarchical network architectures of carbon fiber/paper supported cobalt oxide nanonet for high-capacity pseudocapacitors

作者L. Yang, S. Cheng, Y. Ding, X.B. Zhu, Z.L. Wang and M.L. Liu

期刊名称Nano Letter

期卷12:321-325

简单介绍 We present a high-capacity pseudocapacitor based on a hierarchical network architecture consisting of Co3O4 nanowire network (nanonet) coated on a carbon fiber paper. With this tailored architecture, the electrode shows ideal capacitive behavior (rectangular shape of cyclic voltammograms) and large specific capacitance (1124 F/g) at high charge/discharge rate (25.34 A/g), still retaining ～94% of the capacitance at a much lower rate of 0.25 A/g. The muchimproved capacity, rate capability, and cycling stability may be attributed to the unique hierarchical network structures, which improves electron/ion transport, enhances the kinetics of redox reactions, and facilitates facile stress relaxation during cycling.


论文标题CNF-grafted carbon fibers as a binder-free cathode for LithiumeOxygen batteries with a superior performance

作者Xingbao Zhu a,*, Yuanguo Wu a, Weihua Wan b,c, Yingzhang Yan a, Yu Wang a, Xianglei He a, Zhe Lv

期刊名称ScienceDirect

期卷43:739-747

简单介绍In this work, we report the significant enhancement of the electrochemical performance and flexibility of a lithium–oxygen battery by introducing a free-standing, binder-free carbon nano-fibers (CNF) grafted carbon paper cathode with a bimodal pore architecture. The small pore structures (65100nm) accommodated Li 2 O 2 , and the large pore structures (6510μm) enabled effective oxygen diffusion without clogging the pores. This kind of cathode overcame some troubles of the cathode prepared by spraying coating method, such as the low utilization of substrate surface, the unreasonable aperture structure and the aggregation of active carbon material. As a result, this electrode structure imparted stability to active sites during the recovery of discharge products to the initial state, providing long-term cyclability of more than 800 cycles in a 1M LiTFSI/TEGDME electrolyte system. In addition, the battery output a discharge capacity as high as 20000mAhg 611 at 468mAg 611 and exhibited a charge/discharge rate as high as 1136mAg 611 (0.57mAcm 612 ). The test results suggest that these CNF-grafted carbon papers have the potential to be used for oxygen/air electrodes for next-generation lithium-oxygen batteries, though the present results need to be improved to achieve performance of practical significance, namely with regard to (i) cathode mass loading to get higher areal capacity, and (ii) cycling performance at higher current density.

作者Xingbao Zhu a,？, Yingzhang Yan a, Weihua Wan b,c, Yu Wang a, Yuanguo Wu a, Xianglei He a, Zhe Lü

期刊名称Materials Letters

期卷215:71-74

简单介绍Here, we report a high performance biomass-derived cathode material. Compared to traditional carbonmaterials, biomass-derived carbon, prepared through the pyrolysis of yeast followed by activation withKOH, shows a great improvement in both catalytic activity and stability. A lithium–oxygen battery thatuses the yeast-derived carbon as its cathode presents a discharge capacity of 22,100 mAh gu00011 at 570 mAgu00011, and sustains more than 500 cycles at a fixed capacity of 1360 mAh gu00011. Moreover, the rate capabilityreaches as high as 3390 mA gu00011, a value which is nearly an order of magnitude higher than that of conventional lithium–oxygen batteries. This work will provide a new direction for choosing cathode materialfor energy conversion and storage.


论文标题Continuous conversion of biomass wastes in a La0.75Sr0.25Cr0.5Mn0.5O3-δ based carbon-air battery

作者X.B. Zhu*, Y.Q. Li, and Z. Lv

期刊名称Int. J. Hydrogen Energy

期卷41：5057-5062

简单介绍In this study, a carbon–air battery based on a solid oxide fuel cell (SOFC) is demonstrated to continuously generate electric power through a direct oxidation of the biomass wastes. Due to inevitable poisoning gases such as H 2 S, SO 2 , CO 2 in wastes, more stable La 0.75 Sr 0.25 Cr 0.5 Mn 0.5 O 3–δ (LSCM) instead of Ni is used as the anode material for SOFC. Nano– and/or micro–particles of LSCM are prepared onto a 3D porous yttria–stabilized zirconia (YSZ) scaffold via an infiltration process, in which YSZ backbone provides rich pathways for O 261 which can remedy the major defect of the LSCM, negligible O 261 conductivity, and thus expanding the triple–phase boundary (TPB) to the whole anode. When falling leaves are tucked into the anode chamber, an attractive performance of 330mWcm 612 can be reached for the battery at 800°C, which is among the best in the published open literature. There is no visible degradation in cell performance during stability-test for 1000min. This work provides a novel waste fed SOFC system that has a wide range of application potentials due to its unique advantages of low cost, low emission and high efficiency.

期刊名称Mater. Lett

期卷92:192-194

简单介绍A uniform and dense (relative density 89%) La0.8Sr0.2MnO3u0002d (LSM) thin film (84 nm thick) has beenprepared on La0.6Sr0.4Co0.2Fe0.8O3u0002d (LSCF) substrate using a water-based sol–gel method, in order toimprove the operating stability of intermediate temperature cathode. An in situ static electric field wasapplied in the deposition/drying process, and found to obviously affect phase formation and thicknessof the final LSM film. It was proposed that the orientation of macromolecules (such as chelating agentsand surfactants) and the packing density of metal cations may be influenced by electric field during thedeposition process.


论文标题Preparation of LSM-nano-film via a water-based impregnation process and its application onto porous LSCF cathode

作者 X.B. Zhu, Z. Lü* and L. Zhen

期刊名称 J. Electrochem

期卷106:F905-F909

简单介绍The aim of this work is to develop and evaluate a novel composite cathode with prominent stability for the operation of solid oxide fuel cell (SOFC). A La0.85Sr0.15MnO3 (LSM) nano-film has been successfully prepared onto a porous La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) cathode via a water-based impregnation process, with the help of control system for LSM-film deposition. The quality of LSM-film is found to be influenced much by drying process, especially relative humidity (RH). The LSM-film is used to improve the operational stability of the LSCF cathode through surface treatment. The interfacial polarization resistance of LSCF cathode is reduced by 20% at 750°C after the introduction of LSM thin-film coating. It is found that the polarization behavior of blank LSCF cathode and LSM-film modified LSCF cathode is strikingly different especially under cathodic bias. A stable (even increasing) power output is observed for modified LSCF cathode, by contrast, 8% degradation is observed for blank LSCF cathode for ～100 h operation of SOFC at 750°C.

期刊名称Int. J. Hydrogen Energy

期卷38:5375-5382

简单介绍Uniform, dense and continuous coatings of La 0.8 Sr 0.2 MnO 3？δ (LSM) have been successfully deposited on dense/porous La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3？δ (LSCF) substrates via a one-step drop-coating process using a water-based solution in order to improve the operating stability of solid oxide fuel cell cathode. The processing conditions were optimized by precise control of the composition of infiltrating solution, including chelating agents (glycine, citric acid and ethylene glycol), surfactants (polyvinyl alcohol (PVA), polyethylene glycol (PEG) and polyvinyl pyrrolidone (PVP)) and pH values (5.25, 4.29, 3.01 and 2.09). Ethanol was found to improve the wetting ability of the water-based solution significantly, but unfortunately causing precipitation. The symmetrical and full cells tests demonstrated that both performance and stability of LSCF cathode can be enhanced by surface modification with an optimized LSM film coating, leading to ～31% reduction in cathodic polarization resistance and ～45% improvement in power density (without observable degradation) for almost 350 h operation at 750 °C under a constant voltage of 0.7 V.

论文标题A direct flame solid oxide fuel cell for potential combined heat and power generation

期刊名称Int. J. Hydrogen Energy

期卷37:8621-8629

简单介绍A sealant-free solid oxide fuel cell (SOFC) micro-stack was successfully operated inside a liquefied petroleum gas (LPG) flame during cooking. This micro-stack consisted of 4 single cells with infiltrated La0.75Sr0.25Cr0.5Mn0.5O3-δ (LSCM) based composite anodes, achieving an open circuit voltage of 0.92 V and a peak power density of 348 mW cm？2. This performance is significantly better than that of stack with its cathode operation outside flame. The results confirmed that the perovskite oxide anode showed good properties of carbon-free, redox-stability, quick-start (less than 1 min) and successful operation under a wide range of oxygen partial pressure. For comparison, the conventional Ni/yttria-stabilized zirconia (Ni/YSZ) anode was prepared and tested under the same conditions, showing an open circuit voltage of 0.915 V and a peak power density of 366 mW cm？2, but obvious carbon deposition, poor stability and slow/difficult-start. The direct flame SOFC (DFFC) with a new configuration and design has a potential for combined heat and power generation for many applications.


论文标题 A symmetrical solid oxide fuel cell prepared by dry-pressing and impregnating methods

作者X.B. Zhu, Z. Lü*, B. Wei, X.Q. Huang, Y.H. Zhang and W.H. Su

期刊名称J. Power Sources

期卷196:729-733

简单介绍In this study, a simple and cost-effective dry-pressing method has been used to fabricate a symmetrical solid oxide fuel cell (SOFC) where the dense yttria-stabilized zirconia (YSZ) electrolyte film is sandwiched between two symmetrical porous YSZ layers in which La 0.75 Sr 0.25 Cr 0.5 Mn 0.5 O 361 δ (LSCM) based anode and cathode are incorporated using wet impregnation techniques. The maximum power densities ( P max ) of a single cell with 3202wt.% LSCM impregnated YSZ anode and cathode reach 333 and 26502mW02cm 612 at 90002°C in dry H 2 and CH 4 , respectively. The cell performance is further improved with additional impregnation of a small amount of Sm-doped CeO 2 (SDC) or Ni. When 602wt.% Ni as catalyst is added to both the anode and cathode, P max values of 559 and 54702mW02cm 612 can be achieved, which are better than with SDC. The effect of Ni on the cathode performance is also investigated by impedance spectra analysis.

简单介绍La0.75Sr0.25Cr0.5Mn0.5O3？？ (LSCrM)-impregnated anodes have been fabricated by infiltrating 70% porousyttria-stabilized zirconia (YSZ) matrixes with an LSCrM solution. In these anodes, LSCrM is a primary electronic conducive phase while the well-sintered YSZ provides an ionic-conducting pathway throughoutthe electrode. The maximum power densities of a single cell with YSZ + 35 wt.% LSCrM composite anodereach 567 and 561 mW cm？2 at 850 ？C in dry H2 and CH4, respectively. Further, Ag and Ni are addedvia nitrate impregnating method for improving electronic conductivity and catalytic activity. With theaddition of 6 wt.% Ni and 2 wt.% Ag to the YSZ + 32 wt.% LSCrM composite anode, the maximum power densities at 850 ？C increase to 1302 mW cm？2 in dry H2 and 769 mW cm？2 in dry CH4. No carbon depositionis detected in the tested anodes, even with the presence of Ni

期卷55:3932-3938

简单介绍In this paper, La 0.75Sr 0.25Cr 0.5Mn 0.5O 361 δ (LSCrM) and Ni impregnated porous yttria-stabilized zirconia (YSZ) anodes have been fabricated in two different ways. The testing results demonstrated the excellent performance of the anode made by infiltrating a mixture of LSCrM and Ni(NO 3) 2 solutions into porous YSZ matrix. After reduction of the anode with hydrogen, an inner nano-network structure with mixed ionic-electronic conducting path has been formed within and between these added particles. A single cell with the anode at 800 °C exhibited the maximum power densities of 1151 and 704 mW cm 612 when dry H 2 and CH 4 were used as the fuels, respectively; under the same conditions, the cell performances for LSCrM and Ni impregnated YSZ anode separately were 810 and 508 mW cm 612. A cavity model was proposed to simulate the impregnating process and the loading was calculated. No carbon deposition was detected in the anode, even with the presence of Ni, after operation in dry CH 4 for about 6 h under open-circuit condition.

期卷157:B1838-B1843

简单介绍In the present study, the performances of a single solid oxide fuel cell (SOFC) and a micro-SOFC stack fueled with flame of combusting liquefied petroleum gas (LPG) were studied. La(0.75)Sr(0.25)Cr(0.5)Mn(0.5)O(3-delta) and Ni coimpregnated yttria-stabilized zirconia were used as the anode material of the direct-flame SOFC. The operation temperature of the cell can be sustained at 500-700 degrees C for the combustion of LPG. With the anode facing the LPG flame and the La(0.8)Sr(0.2)MnO(3-delta) cathode freely exposing to ambient air, the single cell exhibited an open-circuit voltage (OCV) of more than 0.85 V and the maximum power density (P(max)) of 238 mW/cm(2). The micro-SOFC stack with three single cells connected in series demonstrated an OCV of 2.5 V and the maximum power output of 64 mW (corresponding to a P(max) of 139 mW/cm(2)). The cell performance was found to be strongly influenced by the cell temperature. And the temperature is determined by cell position and gas composition. Additionally, the cell stability and carbon deposition after operation on the diffusion flame of the LPG were also tested.

简单介绍Fe-doped u0001La,Sru0002CrO3？u0001 u0001LSCrFeu0002 oxide was modified as the anode of solid oxide fuel cells. Through vacuum-assisted impregnation processes, nanosized Sm-doped CeO2 u0001SDCu0002 and Ni particles were introduced into an anode backbone. With Ni and SDCcoimpregnated LSCrFe anodes, the maximum power densities at 900°C reached 765 and 271 mW cm？2 with H2 and CH4 asfuels, respectively, which were much higher than that with a nonmodified LSCrFe anode. Our results indicated that nanosized Niparticles played a primary role in performance enhancement. No carbon deposition was detected for all tested LSCrFe-basedanodes.

简单介绍The optimization of electrodes for solid oxide fuel cells (SOFCs) has been achieved via a wet impregnation method. Pure La 0.75Sr 0.25Cr 0.5Mn 0.5O 361 δ (LSCrM) anodes are modified using Ni(NO 3) 2 and/or Ce(NO 3) 3/(Sm,Ce)(NO 3) x solution. Several yttria-stabilized zirconia (YSZ) electrolyte-supported fuel cells are tested to clarify the contribution of Ni and/or CeO 2 to the cell performance. For the cell using pure-LSCrM anodes, the maximum power density ( P max) at 850 °C is 198 mW cm 612 when dry H 2 and air are used as the fuel and oxidant, respectively. When H 2 is changed to CH 4, the value of P max is 32 mW cm 612. After 8.9 wt.% Ni and 5.8 wt.% CeO 2 are introduced into the LSCrM anode, the cell exhibits increased values of P max 432, 681, 948 and 1135 mW cm 612 at 700, 750, 800 and 850 °C, respectively, with dry H 2 as fuel and air as oxidant. When O 2 at 50 mL min 611 is used as the oxidant, the value of P max increases to 1450 mW cm 612 at 850 °C. When dry CH 4 is used as fuel and air as oxidant, the values of P max reach 95, 197, 421 and 645 mW cm 612 at 750, 800, 850 and 900 °C, respectively. The introduction of Ni greatly improves the performance of the LSCrM anode but does not cause any carbon deposit.

简单介绍A novel La2NiO4+δ-La3Ni2O7？δ-Ce0.55La0.45O2？δ (L2N1-L3N2-LDC) ternary composite with a weight ratio of 0.3:2.5:2.2 was prepared by a one-step co-synthesis method and employed as cathode material for intermediate temperature solid oxide fuel cells (IT-SOFCs). X-ray diffraction (XRD) profiles confirmed the successful synthesis of the composite consisted of L2N1, L3N2 and LDC phases, without any other impurity. Compared with the cathode prepared by the physical mixing method, the co-synthesized composite cathode possessed a porous microstructure with the smaller particle size and more uniform distribution of various elements. The ternary composite cathode on Sm0.2Ce0.8O1.9 (SDC) electrolyte revealed improved electrochemical performance, achieving the polarization resistance value of 0.06 Ω cm2 at 800° C in stationary air. Electrochemical impedance spectra under various oxygen partial pressures indicated the charge transfer process was the rate limiting step for oxygen reduction reaction. Furthermore, a SDC electrolyte (about 350 μm) supported single cell with L2N1-L3N2-LDC as cathode and Ni-SDC as anode demonstrated a maximum power density of 253 mW cm？2 at 800° C. These results confirmed that L2N1-L3N2-LDC ternary composite prepared by co-synthesized method is a very promising cathode material for IT-SOFCs.

简单介绍In this paper, a composite cathode material consisted of 70 wt % La2NiO4+δ and 30 wt % Ce0.55La0.45O2-δ (LNO-LDC) was synthesized by co-synthesized method. The LNO-LDC composite cathode was coated on Sm0.2Ce0.8O1.9 electrolyte and its electrochemical performance was evaluated. The co-synthesized LNO-LDC cathode showed excellent electrochemical performance, demonstrating a polarization resistance of 0.06 Ω cm2 at 800 °C, which is significantly lower than that of physically mixed LNO-LDC composite cathode under the same operating condition. The enhanced electrochemical performance was mainly due to the reduced particle size and improved dispersion uniformity of the two phases, leading to increase of the two phase boundary (2 PB) and triple-phase boundary (3 PB). Furthermore, impedance spectra under various oxygen partial pressure determined that the rate-determining step of the co-synthesized LNO-LDC cathode is the charge transfer process. The obtained results indicated that co-synthesized method is a simple and effective method to fabricate high-performance LNO-LDC composite for intermediate temperature solid oxide fuel cells (IT-SOFCs).

简单介绍Pr and Ti co-doped strontium ferrite oxide Pr0.3Sr0.7Ti0.3Fe0.7O3？d (PSTF) has been examined as a hydrogen electrode for solid oxide electrolysis cell (SOEC). X-ray diffraction analysis shows that the PSTF material maintains phase stability during 20 hours of treatment under 5%H2/N2 conditions. An SOEC with a configuration of PSTF||SDC|YSZ||LSM-YSZ operates under various H2O concentrations and current densities. As can be observed from the AC impendence spectra of the PSTF electrode, H2O/H2 adsorption desorption or surface diffusion process is the main rate-limiting step for steam electrolysis reaction. The low-frequency arc RL obviously depends on the H2O concentration and the electrolysis current density. Steam starvation in hydrogen electrode occurs at low H2O concentration and large current density. A maximum current density of 302 mA cm？2 is obtained at an electrolysis voltage of 1.46 V in Ar/H2/60%H2O at 800 °C. The corresponding polarization resistance of PSTF electrode is as small as 0.25 Ω cm2. This study demonstrates that Pr0.3Sr0.7Ti0.3Fe0.7O3？δ is a promising hydrogen electrode material of SOEC for H2O electrolysis.

简单介绍Sulfur poisoning and subsequent oxidative regeneration of La0.75Sr0.25Cr0.5Mn0.5O3？δ (LSCrM) anode by pure O2 were studied using a model solid oxide fuel cell with yttria-stabilized zirconia (YSZ) electrolyte. Utilization of H2 fuel containing 50 ppm (v) of H2S was found to result in increasing polarization resistance of LSCrM anode and degradation of overall cell performance, mainly due to absorption of sulfur and formation of metal sulfides. The electrochemical performance of the cell can be recovered after first two poisoning-oxidative regeneration cycles. Oxidative treatment made it possible to remove the absorbed sulfur and to oxidize metal sulfide. Progressing microstructure changes in LSCrM anode with increasing number of alternative poisoning-regeneration cycles lead however to irreversible degradation.

简单介绍Sr-doped LaMnO3 (LSM)/MnO2 composites show different electrochemical performance and thus indicate that LSM has a positive effect on the capacitance of MnO2 electrode. A typical LSM(10 wt%)/MnO2 electrode presents a higher capacitance of 287.8 F g？1 in 1.0 M Na2SO4 aqueous solution, comparing to the pristine MnO2 electrode, 251.7 F g？1. More interesting, LSM can evidently improve the capacitance of MnO2 electrode under the high rate discharging condition. Compared with the pristine MnO2, LSM(10 wt%)/MnO2 shows excellent capacitance improvement of 11% at low scan rate of 2 mV s？1, 33% at intermediate scan rate of 50 mV s？1 and 47.1% at a high scan rate of 200 mV s？1, respectively. The higher the discharge rate is, the better capacitance improvement can be obtained. Moreover, LSM/MnO2 composite electrode also exhibits excellent cycle performance even after 1000 cycles. These characteristics suggest that LSM/MnO2 composites are promising electrode materials for supercapacitor with high performance.

期卷325:329-336

简单介绍In this work, we present a simple and cost-effective method to form a dual-scale porous electrode byKOH activation of the fibers of carbon papers. The large pores (~10 mm), formed between carbon fibers,serve as the macroscopic pathways for high electrolyte flow rates, while the small pores (~5 nm), formedon carbon fiber surfaces, act as active sites for rapid electrochemical reactions. It is shown that theBrunauer-Emmett-Teller specific surface area of the carbon paper is increased by a factor of 16 whilemaintaining the same hydraulic permeability as that of the original carbon paper electrode. We thenapply the dual-scale electrode to a vanadium redox flow battery (VRFB) and demonstrate an energyefficiency ranging from 82% to 88% at current densities of 200-400 mA cm2, which is record breaking asthe highest performance of VRFB in the open literature.

期卷182:569-575

简单介绍Most non-aqueous lithium-air batteries reported in the literature are limited to operating with pure oxygen. To practically operate the battery in ambient air, understanding how the battery鈥檚 performance varies with humidity of moist air is essential. Here we study the effects of moist air on the cycling performance through operating a non-aqueous lithium-air battery with a stable anode and a nano-structured RuO2/NiO cathode at various relative humidities. Results show that in the dry air, the discharge and charge terminal voltages are around 2.51 and 4.12 V, respectively, but change to 2.79 and 3.87 V when the relative humidity reaches 84%. The energy efficiencies corresponding to the dry air and the relative humidity of 84% are 66.2% and 73.8%, respectively. The improved performance is found to be mainly due to the increased fraction of LiOH among the discharge products at high relative humidities. The discharge voltage for the formation of LiOH is higher than that for the formation of Li2O2, while the charge voltage for the decomposition of LiOH is lower than that for the decomposition of Li2O2. The results suggest that to enable a non-aqueous lithium-air battery to operate in moist air, in addition to protecting the lithium anode from water, designing a cathode with electrocatalytic activities for the decomposition of both Li2O2and LiOH is required.

简单介绍Conventional vanadium redox flow batteries (VRFBs) using Nafion 115 suffered from issues associatedwith high ohmic resistance and high capital cost. In this work, we report a commercial membrane(VANADion), consisting of a porous layer and a dense Nafion layer, as a promising alternative toNafion 115. In the dual-layer structure, the porous layer (210 lm) can offer a high ionic conductivityand the dense Nafion layer (20 lm) can depress the convective flow of electrolyte through the membrane.By comparing with the conventional Nafion 115 in a VRFB, it is found that the change from theconventional Nafion 115 to the composite one results in an increase in the energy efficiency from71.3% to 76.2% and an increase in the electrolyte utilization from 54.1% to 68.4% at a current density ofas high as 240 mA cm？2. In addition, although two batteries show the comparable cycling performanceat current densities ranging from 80 mA cm？2 to 240 mA cm？2, the composite membrane is estimatedto be significantly cheaper than the conventional Nafion 115 due to the fact that the porous layer is rathercost-effective and the dense Nafion layer is rather thin. The impressive combination of desirable performanceand low cost makes this composite membrane highly promising in the VRFB applications.

简单介绍Novel perovskite-type La 0.3 Sr 0.7 Fe 0.7 Ti 0.3 O 3 (LSFT) oxide is investigated as both anode and cathode materials in a symmetrical solid oxide electrolysis cell (SOEC) for direct electrolysis of pure CO 2 at 80002°C. The current density is 52102mA02cm 61022 at an applied voltage of 2.002V. The lowest polarization resistance R p of this symmetrical SOEC is obtained at 2.002V with a value of as low as 0.0802Ω02cm 2 , which is much lower than that of other perovskite and Ni-cermet cathode. LSFT cathode also shows excellent durability in pure CO 2 electrolysis, especially at high voltage of 2.002V. Our results indicate that the LSFT is a promising alternative electrode material for CO 2 electrolysis.

简单介绍In this work, we synthesize inexpensive Vulcan XC-72 carbon supported Fe 2 O 3 nanoparticles (Fe 2 O 3 /XC) as an oxygen evolution reaction (OER) catalyst for non-aqueous lithium-oxygen batteries. It is demonstrated that the battery with the Fe 2 O 3 /XC cathode exhibits a charge voltage plateau of 4.0102V at a current density of 20002mA02g 611 , which is 0.4302V lower than that with the pure XC carbon cathode. The battery also presents an outstanding rate capability, giving a charge voltage plateau of 3.99, 4.01 and 4.1502V at the current density of 100, 200 and 40002mA02g 611 , respectively. Furthermore, the battery can be operated for 50 cycles at a fixed capacity of 50002mA h g 611 without obvious degradation, showing its superior cycling stability. The results suggest that the iron oxide is a cost-effective catalyst for non-aqueous lithium-oxygen batteries.

Furthermore, the composite electrode also has a higher rate capability (capacitance improvement can reach to 70%) and better cycling stability. It is believed that the present results provide an efficient electrode materials design and a novel composite for the future practical application of high-performance supercapacitor.

期卷306 ：724-732

简单介绍Manganese dioxide (MnO2) has been recognized as an effective catalyst for the oxygen reduction and oxygen evolution reactions in non-aqueous lithium-oxygen batteries. However, a further improvement in battery performance with the MnO2 catalyst is limited by its low electronic conductivity and catalytic activity, which strongly depend on the morphology and composition. In this work, we develop a carbon- and binder-free MnO2-x nanosheets/stainless steel (SS) cathode via a simple and effective electrodeposition-solvothermal route. The created Mn(III) and oxygen vacancy in MnO2-x nanosheets allows an significant increase in the electronic conductivity and catalytic activity. It is experimentally shown that the use of the present nanostructure MnO2-x/SS cathode in a non-aqueous lithium-oxygen battery results in a rechargeable specific capacity of 7300 mAh g-1 at a current density of 200 mA g-1, which is 39% higher than that with the MnO2/SS cathode. In addition, the specific capacities at 400 mA g-1 and 800 mA g-1 reach 5249 mAh g-1 and 2813 mAh g-1, respectively, which are over 30% higher than that with the MnO2/SS cathode. Furthermore, the discharge/charge cycle test shows no degradation for 120 cycles. All the results show that the present nanostructure MnO2-x/SS cathode is a promising candidate for high-performance lithium-oxygen batteries.

简单介绍We report a non-aqueous lithium–oxygen battery with its cathode made of a RuO2 nanoparticle-decorated buckypaper (weaved with carbon nanotubes). Compared with conventional slurry-formed cathodes, the present cathode has two striking features: (i) no binder is required, avoiding the problems of surface-loss and instability due to the introduction of a polymeric binder, and (ii) no additional current collector is needed, increasing the practical specific capacity. The present battery demonstrates a discharge plateau of 2.56 V and a charge plateau of 4.10 V at a current density of 0.4 mA cm？2, with a discharge capacity of 4.72 mA h cm？2 (1150 mA h gcathode？1). It is also shown that at a fixed capacity of 2.0 mA h cm？2, the energy efficiency of the battery reaches 71.2%, 65.4%, and 58.0% at a current density of 0.2, 0.4, and 0.8 mA cm？2, respectively. Furthermore, the battery is able to operate for 50 cycles at a fixed capacity of 1.0 mA h cm？2, showing its good cycling stability. The results suggest that the RuO2 nanoparticle-decorated buckypaper cathode offers promise for a high-practical specific capacity, high-energy efficiency, and stable electrode for non-aqueous lithium–oxygen batteries.

简单介绍The development of non-carbon electrodes for nonaqueous lithium–oxygen batteries has become a recent focus as carbon electrodes were found to be unstable. Conventional non-carbon electrodes are typically formed with a substrate/current collector, which will decrease the practical capacity. Here, we propose an integrated porous electrode made of LaNiO3 that does not require a substrate/current collector. The porous structure allows the formation of nanosized pores on the walls of microsized pores, which facilitates the transport of both oxygen and lithium ions. Importantly, all the surfaces of the porous structure are catalytically active for electrochemical reactions. Experimental results show that the adoption of the electrode in the battery enables a capacity of 1.064 mAh cm？2 at a current density of 0.05 mA cm？2. Furthermore, it is demonstrated that the battery can be cycled for at least 25 cycles at a fixed capacity of 0.3 mAh cm？2, and the electrode shows no degradation after the cycles.

简单介绍In this study, comparison experiments are conducted based on yttria-stabilized zirconia (YSZ) electrolyte supported single solid oxide fuel cells (SOFCs) with pure La 0.75 Sr 0.25 Cr 0.5 Mn 0.5 O 361δ (LSCrM) or Ni/CeO 2 impregnated LSCrM anodes. The single cells are tested in dry H 2 and H 2 /H 2 S (50ppm) mixture, respectively. Compared with the pure LSCrM anode, the cell with Ni/CeO 2 impregnated LSCrM presents a significant performance improvement when the pure H 2 is fueled to the anode, and shows a good stability during a constant-current discharge testing (398mAcm 612 ). When the fuel is switched to H 2 /H 2 S mixture, the cell with Ni/CeO 2 impregnated LSCrM anode still shows a remarkable constant-current discharge (120mAcm 612 ) performance compared with pure LSCrM anode. The Ni/CeO 2 impregnation can improve the electrochemical performance of the LSCrM anode without any sacrifice of sulfur tolerance ability. The Ni/CeO 2 impregnated LSCrM might be a potential anode material for solid oxide fuel cell operating in sulfur-containing fuels. The XRD and XPS results demonstrate that the anode poisoning product is composed of adsorbed sulfur, metal sulfides and sulfate radical. The mass spectrum result confirms that the poisoning mechanism involves the reaction of sulfur with anode rather than the direct reaction between H 2 S gas and anode.

简单介绍YSZ (Y 2 O 3 -stabilized ZrO 2 )/SDC (Sm-doped CeO 2 ) bilayer electrolyte film was successfully fabricated on NiO/YSZ anode substrate using stepwise sintering processing by screen-printing technique. OCVs (open-circuit voltages) of 1.0602V, 1.0502V and 0.8802V were achieved at 75002°C for single cells with bilayer electrolyte of 1202μm-SDC/802μm-YSZ, 1202μm-SDC/502μm-YSZ, and 1202μm-SDC/202μm-YSZ, respectively. Interdiffusion of ions at YSZ/SDC interface and formation of YSZ–SDC solid solution after sintering at 140002°C for 202h was investigated. The EDX result suggested that the region for the interdiffusion in a YSZ/SDC bilayer structure was 2.002μm from the YSZ/SDC interface into the YSZ layer for Sm and Ce, and 0.502μm into the SDC layer for Zr and Y. The YSZ–SDC solid solution exhibited a low electrical conductivity, which negatively affected the performance of single cell. After two thermal cycles, the maximum power density of the single cell exhibited a significant decrease. The destruction of YSZ/SDC bilayer electrolyte structure was not observed during the thermal cycles.

简单介绍In this paper, the surface properties of the (001) surface in PrMnO 3 are investigated using the projector augmented plane wave (PAW) methods within the spin-polarization generalized gradient approximation (GGA+ U ), where U is on-site Coulomb interaction correction. The result of the total density of states shows a half-metallic ground state for PrMnO 3 in GGA+ U treatment. The optimized structure parameters of both cubic and orthorhombic bulk phases are obtained. The electronic properties of the cubic PrMnO 3 (001) surface with PrO- and MnO 2 -terminations are discussed. Based on the results of the calculated surface energies, we predict the surface energies of three low-index surfaces follows the sequence of (001)<(111)<(110). The rumpling for the PrO-terminated surface is much larger than that of the MnO 2 -terminated surface. Both the PrO- and MnO 2 -terminated surfaces display a reduction of d 12 interlayer distance and an expansion of d 23 . Bader effective charge of the ion is much smaller than its formal charge which is due to the partial Mn鈥揙 bond covalency. The oxygen-vacancy formation energy in bulk PrMnO 3 is found to be smaller than other perovskites, e.g. LaMnO 3 and SrTiO 3 . We find that the formation energy of oxygen-vacancy on MnO 2 -terminated surface is lower than the formation energy of oxygen-vacancy on PrO-terminated surface and Sr-doped PrMnO 3 makes oxygen-vacancy formation more easily compared pure PrMnO 3

XRD result suggested that no chemical reaction occurred between LPSN and CPO after sintering at 1200°C for 4h. Electrical conductivity of LPSN- x CPO decreased with x . LPSN-40CPO exhibited the best performance on cathode impedance spectra under open-circuit condition. At 700°C, Exchange current density of LPSN-40CPO and LPSN was 50.1 and 15.8mAcm 612 , respectively, and the polarization resistance R P of LPSN-40CPO was 0.22Ωcm 2 , which is about one-eighth of that of LPSN. The OCV of the cell with LPSN-40CPO as cathode was about 0.78V, and the maximum of power density was about 88mWcm 612 . LPSN-40CPO can be a promise candidate for cathode in IT-SOFC.

简单介绍The intrinsically poor electrical conductivity of transition metal oxides is a critical challenge to obtain high electrochemical performance when these materials are used as the electrode of supercapacitors. In this study, the pseudo-capacitance features of perovskite (La0.75Sr0.25)0.95MnO361δ(LSM) having a high electric conductivity of 44.9 S cm611at room temperature was preliminarily investigated. The easily prepared LSM electrode was characterized by cyclic voltammetry and galvanostatic charge–discharge method to evaluate its electrochemical performances. The results show that LSM has pseudo-capacitance features and the specific capacitance is 56 F g611at a scanning rate of 2 mV s611. This is the first report on the pseudo-capacitance value of LSM. Furthermore, the electrodes show no obvious capacitance degradation after 1000 cycles.

简单介绍Abstract A 7065wt.% Sm0.5Sr0.5CoO3 – 30 wt.% Sm0.2Ce0.8O1.9 (SSC–SDC73) composite cathode was co-synthesized by a facile one-step sol–gel method, which showed lower polarization resistance and overpotential than those of physically mixed SSC–SDC73 cathode. The polarization resistance of co-synthesized SSC–SDC73 cathode at 80065°C was as low as 0.0365Ω65cm2 in air. Scanning electron microscopy (SEM) images showed that the enhanced electrochemical property was mainly attributed to the smaller grains and good dispersion of SSC and SDC phases within the composite cathode, leading to an increase in three-phase boundary length. The dependence of polarization resistance with oxygen partial pressure indicated that the rate-limiting step for oxygen reduction reaction was the dissociation of molecular oxygen to atomic oxygen process. An anode supported fuel cell with a co-synthesized SSC–SDC73 cathode exhibited a peak power density of 92465mW65cm612 at 80065°C. Our results suggested that co-synthesized composite was a promising cathode for intermediate temperature solid oxide fuel cells (IT-SOFCs).

期卷134：136-142

简单介绍Large thermal mismatch between GdBaCo2O5+δ (GBCO) oxide and solid electrolytes remains a challenge for its application as a cathode of solid oxide fuel cells (SOFCs). To avoid sharp discontinuities in composition, a functionally graded GBCO cathode is developed, which consists of an inner layer with high electrochemical activity and good thermal compatibility to electrolyte, and an outer layer with high electrical conductivity for current collection. Impedance spectra results reveal that the graded GBCO cathode shows a reduced polarization resistance and more importantly, an improved thermal stability during thermal cycling test. The present work confirms the advantage of graded GBCO cathode that is more robust and reliable for practical application.

简单介绍In this study, we will report our investigation for La 0.75 Sr 0.25 Cr 0.5 Mn 0.5 O 361 δ (LSCrM) based anodes impregnated with solutions of cobalt (Co) nitrate. A YSZ supported SOFC with pure LSCrM anode and La 0.7 Sr 0.3 MnO 3 (LSM) cathode exhibits the maximum power density ( P max ) of 58.7 and 5.2mWcm 612 at 850°C in dry H 2 and dry CH 4 . After the modification of anode with Co nitrate, the P max reaches 196.2mWcm 612 in dry H 2 and 28.5mWcm 612 in dry CH 4 , about 3.34 times and 5.48 times increase, respectively. These results indicate that Co is also a potential catalyst for LSCrM anode. Moreover, the effect of impregnation amount of catalyst on the cell performance is also evaluated in this study.

期卷13：1043-1047

简单介绍Abstract Density functional theory calculations are employed to investigate the adsorption of sulfur-containing species on the (001) surface of LaCrO 3 (LCrO). Molecular adsorption is found to be stable with H 2 S binding preferentially at O site on the LaO-terminated surface. The adsorption of H 2 S molecule leads to the electrons transferring from the substrate to the molecule and the charges rearrangement within the molecule. In addition, the adsorption of the corresponding S-containing dissociated species (SH and S) is investigated. SH and S are found to be preferentially bind at the Cr site. We further predict the adsorption energies of sulfur-containing species increase following the sequence H 2 S

简单介绍The effect of gas supply method on the performance of a single-chamber solid oxide fuel cell micro-stack and single cells was studied, and a novel gas supply method with separated gas vents in the gas tube was proposed. The traditional gas supply method was also investigated for comparison. Results showed that the single cells could obtain a uniform open-circuit voltage and power output by using the separated gas supply method. For the traditional gas supply method, the cell at the outlet position yielded inferior performance compared to that of the inlet cell. The gas flow rate showed a significant effect on the performance of the cells. Finally, the stack operated with the separated gas supply method produced a higher power output than that operated with the traditional gas supply method.

简单介绍In this study, Ca3Co4O9+0207 (CCO) and La0.7Sr0.3CoO3 (LSC) have been mixed as mass fraction by 1:1, to prepare novel two-phase composites with high electrical conductivity and low thermal expansion coefficient (TEC), for potential application in intermediate-temperature solid oxide fuel cells. The conductivity of the composite, Ca3Co4O9+0207 (**wt.%)090009+090009La0.7Sr0.3CoO3 (**wt.%) (CCO-LSC50), is improved to be three times that of single phase CCO material. And, the TEC of CCO-LSC50 has been effectively improved to be 15.******°C**, about 20% lower than single phase LSC cathode, which ensures better chemical compatibility with adjacent electrolyte. As a result, compared with pure LSC and CCO cathodes, CCO-LSC50 composite cathode improves the electrochemical performance, a percentage of 16 and 84%, respectively, according to the impedance spectra experiments. In addition, cathodic overpotential and oxygen reduction kinetics have also been researched to reveal what is driving the results. The microstructures and phases of cathodes were also compared and analyzed.


论文标题The effect of adding Ce1-xSmxO2-x/2 with different Sm contents on the electrochemical performance of GdBaCo2O5+δ Based composite cathode

期卷 13：289-297

简单介绍In this paper, the Ce1–xSmxO2–x/2 (x = 0.025, 0.05, 0.1, 0.2) samples were synthesized and then mixed with GdBaCo2O5+δ (GBCO) to form GBCO–Ce1–xSmxO2–x/2 composite cathodes. The electrochemical performance of the composite cathodes was investigated by the electrochemical impedance spectroscopy (EIS) as a function of temperature and oxygen partial pressure. The impedance spectra results demonstrated that the introduction of proper Ce1–xSmxO2–x/2 phase remarkably enhanced the electrochemical performance of GBCO cathode and caused a reduction in the total polarization resistance (Rp). Furthermore, as the amount of Ce1–xSmxO2–x/2 in composite cathode was fixed, the variation of Sm content in Ce1–xSmxO2–x/2 also had a significant influence on the electrochemical performance of the GBCO–Ce1–xSmxO2–x/2 cathodes. For example, the Rp of GBCO cathodes containing 10 wt.% Ce1–xSmxO2–x/2 considerably reduced from 0.37 to 0.17 Ω cm2 at 600 °C with the decreasing Sm content x from 0.2 to 0.025. The improvement in performance of the GBCO–Ce1–xSmxO2–x/2 cathodes compared to pure GBCO cathode could be mainly attributed to the catalytic activity of Ce1–xSmxO2–x/2 towards the surface diffusion related processes, which was an elementary step in oxygen reduction reaction at cathode.


论文标题Redox tolerance of thin and thick Ni/YSZ anodes of electrolyte-supported single-chamber solid oxide fuel cells under methane oxidation conditions

期刊名称 Fuel cells

期卷 7：120-125

简单介绍Redox tolerance of 50 and 500 lm thick Ni/YSZ (yttria-stabilized zirconia) anodes supported on YSZ electrolytes were studied under single-chamber solid oxide fuel cell conditions. Open circuit voltage, electrochemical impedance spectra, and discharge curves of the cells were measured under different methane/oxygen ratios at 700 °C. For the cell with the thin anode, a significant degradation accompanying oscillatory behaviors was observed, whereas the cell based on the thick anode was much more stable under the same conditions. In situ local anode resistance (Rs) results indicated that the Ni/NiO redox cycling was responsible for the oscillatorybehaviors, and the cell degradation was primarilycaused by the Ni reoxidation. Reoxidation of the thick anode tookplace at a low methane/oxygen ratio, but the anode can be recovered to its original state by switching to a methanerich environment. On the contrary, the thin anode was unable to be regenerated after the oxidation. Microstructure damage of the anode was attributed to its irreversible degradation.

简单介绍In this paper, a series of Sm0.5Sr0.5CoO3–Sm0.2Ce0.8O1.9 (SSC–SDC) composite with different ratios were prepared and characterized as oxygen electrodes for solid oxide electrolysis cells (SOECs). Yttria‐stabilized zirconia (YSZ) was selected as the electrolyte with a SDC barrier layer to avoid detrimental solid state interaction between SSC and YSZ. At 850？°C, the impedance spectra showed that the optimum SDC content in the composite electrode was found to be about 30？wt.%, which showed a much lower area specific resistance of 0.03？Ω？cm2. The electrochemical performances of a Ni–YSZ hydrogen electrode supported YSZ membrane SOEC with the SSC–SDC73 oxygen electrode were also measured at 750–850？°C. The hydrogen production rate calculated from the Faraday@#%s law was 327？mL？cm–2？h–1 at 850？°C at an electrolysis voltage of 1.3？V with a steam concentration of ～40%, which indicated that the SSC–SDC73 was a promising oxygen electrode candidate for high temperature electrolysis cells.


论文标题Oxygen adsorption on the Ag/La1-xSrxMnO3(001) catalysts surfaces: a first principles study

期刊名称 J. Power Sources

期卷209：158-162

简单介绍The oxygen adsorption on Ag/LSM(**) catalysts surfaces has been investigated using first-principles density functional theory calculations. The most favorable oxygen adsorption sites are found to be atop surface Mn atoms on the MnO 2 -terminated surface and on the hollow positions of the La(Sr)O-terminated LSM(**) surface. The calculated adsorption energies for Ag atom demonstrate that the Ag adsorption at O site is much more favorable than Mn site. The atomic relaxation results indicate that Ag doping produces a strong local perturbation and a large effect on the surface properties. No significant improvement for oxygen adsorption is found due to Ag doping. However, the O 2 adsorption energy increases from 0.49502eV to 0.93702eV due to the pre-adsorbed Ag. It is pre-adsorbed Ag that facilitates O 2 adsorption on surface. The bond length and bond population of O 2 molecule indicate that Ag atom facilitates O 2 molecule dissociative adsorption. The adsorbed Ag on LSM strengthens its activity as SOFCs cathode by acting as an active center at the surface.

简单介绍The perovskite-type La0.9Sr0.1Ga0.8Mg0.2O3-δ(LSGM9182) with high oxygen-ionic conductivity is successfully synthesized using conventional solid-state reaction. The phase composition, grain size distribution, relative density, and oxygen-ionic conductivity of the samples are studied. The XRD result shows that the main perovskite LaGaO3 phase can be produced at 1,250 °C, with trace amount of second phase LaSrGaO4. When the temperature increases to 1,400 °C, the pure phase LSGM can be obtained. The relative density of LSGM pellets sintered at 1,400 °C reaches 98.08%. The average grain size of final powders is ？0.12 μm, which is appropriate for the deposition of LSGM electrolyte film. The ideal oxygen-ionic conductivities of 0.04, 0.06, and 0.08 S cm-1 can be obtained at 700 °C, 750 °C, and 800 °C, respectively. Porous anode supported single cells with LSGM electrolyte film are fabricated using the as-prepared LSGM powders and the cells provide an open-circuit voltage of above 1.0 V, revealing that the LSGM film is gas-tight and crack-free.
