Abstract
A lithium-ion conducting solid electrolyte of the present invention comprises a parent material, a lithium-ion conducting sulfide glass represented by the formula Li.sub.2 S--X (X is at least one sulfide selected from the group consisting of B.sub.2 S.sub.3, SiS.sub.2, P.sub.2 S.sub.5, Al.sub.2 S.sub.3, and GeS.sub.2), and a high-temperature lithium-ion conducting compound (i.e. Li.sub.3 PO.sub.4 or Li.sub.2 SO.sub.4). 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.
