Electrical properties of lithium conductive silicon sulfide glasses prepared by twin roller quenching
Abstract Glasses with the composition xLi 2 S(1-x)SiS 2 [x ⩽ 0.6] have been prepared by twin roller quenching. Their glass transition temperatures and their electrical conductivities have been measured. The conductivity reaches a maximum value of 5.10 −4 (Ω.cm) −1 at 25°C By dissolving a halide salt (LiI) in the matrix, this value has been improved to 8.2 10 −4 (Ω.cm) −1 which is almost the highest conductivity obtained with Li conductive glasses.
