摘　　要：在新一代储能领域中,相比于传统的有机液态电池,全固态电池具有安全性高、能量密度高和循环寿命长等优势,对其电解质的研究更是关注的重点。有机-无机复合固态电解质结合了无机固态电解质高强度、高稳定性、高离子电导率与聚合物固态电解质的质软、易加工的优势,是目前最有潜力的电解质体系。对锂离子固态电解质的基础进行了简介,并着重对有机-无机复合电解质存在的问题(离子电导率、固固界面、电化学窗口及两相相容性)及优化策略进行总结,最后对复合电解质面临的关键挑战和未来发展趋势进行了展望。Compared with conventional organic liquid electrolyte batteries,all-solid-state batteries for next-generation energy storage have attracted recent attention due to their advantages of high safety,high energy density and long cycle life.Organic-inorganic composite solid electrolytes as the most promising electrolyte systems have some advantages of inorganic solid electrolytes with a high strength,a high stability and a high ionic conductivity,and some advantages of solid polymer electrolytes for softness and easy processing as well.This review introduced the fundamentals of Li-ion solid-state electrolytes,and discussed some problems of organic-inorganic composite solid electrolytes(i.e.,ionic conductivity,solid-solid interface,electrochemical window and compatibility between organic and inorganic compounds)and optimization strategies.In addition,some challenges and future development on organic-inorganic composite solid electrolytes were also described.
