Vitreous solid electrolyte sheet having composite material interlayer

Abstract

A Li ion conducting sheet of sulfide glass has a vitreous sheet of Li ion conducting sulfide glass having a first major surface and composite material interlayer on the first major surface of the vitreous sheet. The Li ion conducting sheet may be for use as an interlayer in a battery cell, the composite material layer having a first material component that is an electronically conductive non-metal, typically a carbonaceous material, such as carbon black, and a second material component that is a metal or semi-metal. In a particular embodiment, the second material component may be a transition metal, such as a precious metal, for example silver. The composite material interlayer may be a silver carbon composite.
