摘要
全固态锂电池有望较好地提高电池安全性并实现高的能量密度,因此已成为二次锂电池发展的一个重要方向.发展具有高锂离子电导率、低电解质/电极界面阻抗及有较好应变性的固态电解质材料是全固态电池研究的重要研究课题.如何有效构筑电解质/电极界面,提高界面稳定性并显著降低界面阻抗又是其中的难点之一.本文综述了近年来国际上比较关注的两种无机固体电解质——硫化物与石榴石(garnet)型氧化物的最新研究进展,重点对这两类固体电解质与正负极材料的界面特性进行总结与评述.
All-solid-state lithium batteries have attracted great interest, due to its potential to significantly improve battery safety and realize higher energy density. A solid electrolyte with high Li-ion conductivity, a small electrolyte/electrode （including cathode and anode interface） interfacial resistance and good strain tolerant is a key component in all-solid-state lithium batteries. Rational design of efficient electrolyte/electrode interfaces to improve the stability of interface and significantly decrease the interracial resistance is one of the key challenges in enabling all-solid-state lithium batteries. This paper reviews the state-of-the-art development of some solid electrolytes which has received extensive attention, eg. sulfides and garnet type oxides. Major issues associated with electrolyte/electrode interface of these two type solid electrolytes are summarized and analyzed.
