摘要/Abstract

高性能电解质是制备高能量密度、长循环寿命、良好安全性二次电池的关键材料之一.然而，传统的有机以及水系电解质，由于诸多限制（例如，电位窗口窄、离子电导率低、枝晶、"胀气"和腐蚀等）已不能满足安全、高效二次电池的发展需求.近年来，离子液体-纳米颗粒杂化电解质（IL-NPHE）体系由于具有高稳定、不可燃及多种协同特性而备受关注.专注于IL-NPHE研究的最新进展，对此类电解质体系的物化特性及电化学性能进行了归纳.同时，系统总结了离子液体和无机颗粒之间的协同作用机理.基于上述评述，展望了IL-NPHE的未来发展趋势和方向.

High-performance electrolyte is one of the key materials for achieving secondary batteries with high energy density, long cycle life and good safety. Traditional organic and aqueous systems, however, due to many restrictions (such as narrow potential window, low ionic conductivity, dendrite, gas expansion and corrosion, etc.), are unable to meet the demand of the further development for secondary batteries. In recent years, ionic liquid-inorganic particle hybrid electrolytes (IL-NPHE) have attracted much attention due to their high stabilities, non-combustibilities and various synergistic characteristics. This paper focuses on the latest research progress of IL-NPHE, and summarizes the physicochemical and electrochemical properties of this electrolyte system. Additionally, the synergistic mechanism between ionic liquid and inorganic particles is systematically summarized. Based on the above discussion, the future development trend and direction of IL-NPHE are prospected.
