Abstract:
Inorganic additives-added PEO-based solid composite polymer electrolyte (SCPE) was prepared using solution casting method. The effects of LiNi0.8Co0.2O2 on the physical and chemical properties of the electrolyte were investigated. The products were characterized by X-ray diffraction (XRD), Fourier transform infrared spectrometer (FTIR) and differential scanning calorimetry (DSC). The electrochemical performances of SCPE were measured. Results show that properties of the SCPE are improved significantly by adding LiNi0.8Co0.2O2 into PEO polymer electrolyte. Its conductivity reaches 5×10-4 S/cm(25 ℃) while retaining good mechanical and processing properties.
Key words: solid composite polymer electrolyte electrochemical properties PEO LiClO4 LiNi0.8Co0.2O2
