Among various electrolytes, the sulfide-based materials have the characteristics of high ionic conductivity, wide electrochemical window, low grain boundary resistance and easy film formation, which are promising to be used in all-solid-state batteries. In this paper, we focused on the recent progress of the solid electrolytes with respect to the preparation, characterization and modification of Li₂S-P₂S₅ electrolytes, and stability/compatibility of the interface between the solid electrolyte and the electrode. Moreover, the performance of these solid electrolyte related all-solid-state lithium-ion batteries has also been reviewed. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书修改说明附件1 -->
