摘　　要：固态锂离子电池能量密度高、安全性强,是突破电池技术瓶颈的关键,受到了学术界和工业界的广泛关注。固态电解质是固态电池的核心,其中聚氧化乙烯(PEO)基聚合物固态电解质在改善电极界面相容性方面具有优势,是最有潜力的电解质材料之一。本文系统阐述了PEO与无机填料间的协同作用及其对复合固态电解质的离子传输性和界面相容性的影响机制。首先对PEO基复合固态电解质做出概述,并探讨离子传输相关机制,然后分别综述了PEO-惰性填料和PEO-活性填料复合固态电解质体系的设计、制备、性能及机制,最后对复合固态聚合物电解质的未来发展和优化设计做出展望。Featured with high energy density and sound safety,solid-state lithium-ion battery is the key to breaking through the bottleneck shackling battery technology,gathering wide attention from academia and industry.Solidstate electrolytes are the core of solid-state batteries,among which polyethylene oxide(PEO)polymer solid-state electrolyte excels at improving electrode interface compatibility and is one of the most potential electrolyte materials.This paper systematically elucidated the synergistic effect of PEO with inorganic modified fillers and its influence on ion transport and interfacial compatibility of composite solid-state electrolytes.Following an overview of the PEO-based composite solid-state electrolyte,the mechanism of ion transport was discussed.Then,the design,preparation,performance,and mechanism of PEO-inert filler and PEO-active filler composite solid-state electrolyte systems were reviewed respectively.Finally,an outlook on the future development and optimization design of composite solid-state polymer electrolytes was presented.
