A lithium-ion conducting solid electrolyte.

摘要

A lithium-ion conducting solid electrolyte of the present invention comprises a parent material, a lithium-ion conducting sulfide glass represented by the formula Li2S-X (X is at least one sulfide selected from the group consisting of B2S3, SiS2, P2S5, Al2S3, and GeS2), and a high-temperature lithium-ion conducting compound (i.e. Li3PO4 or Li2SO4). The lithium-ion conducting solid electrolyte has higher ionic conductivity and higher decomposition voltage compared to the parent material. By the use of this solid electrolyte for electrical/chemical components such as batteries, condensers, electrochromic displays, and the like, electronic apparatus that includes such elements may have improved performance.
