摘要
相比于传统液态锂电池,固态锂电池兼具高安全性和高比能量,在学术界和工业界引起了广泛关注.发展具备优异力学性能、高离子电导率和宽电化学窗口的有机-无机复合固态电解质是开发高性能固态锂电池的有效途径之一.近年来,基于聚合物电解质与无机材料的复合型固态电解质成为了研究的热点.基于此,本文回顾了有机-无机复合固态电解质的研究进展,综述了改善固态电解质离子电导率的研究策略,梳理了有机-无机复合固态电解质在固态锂金属电池、固态锂-硫电池和固态锂-空气电池等领域的应用,并对固态锂电池用有机-无机复合固态电解质存在的挑战和未来的发展趋势进行了展望.
Abstract
Compared to traditional liquid-state lithium batteries,solid-state lithium batteries have distinct advantages such as high safety and high specific energy,and have attracted widespread attention in both academia and industry.Exploring organic-inorganic composite solid electrolytes that combine excellent mechanical proper-ties,high ion conductivity,and large electrochemical windows is a feasible solution to developing high-performance solid-state lithium batteries.In recent years,composite solid-state electrolytes based on polymer electrolytes and inorganic materials have become a hot topic.In this tutorial review,we focus on recent advances in various classes of organic-inorganic composite electrolytes and summarize the state-of-the-art strategies for improving the performance(Especially the ionic conductivity)of solid-state electrolytes.This is followed by detailed discussions on the implementation of composite solid-electrolytes in various energy storage systems,including solid-state lithi-um-metal batteries,solid-state lithium-sulfur batteries and solid-state lithium-air batteries,and the current chal-lenges and future opportunities of organic-inorganic composite solid-state electrolytes for lithium batteries are also provided.
