Abstract

Relating to a sulfide-based solid electrolyte compound for lithium ion batteries which has a cubic argyrodite-type crystal structure, to provide a compound which can suppress a generation amount of hydrogen sulfide when being left to stand in the air and which can maintain high conductivity even when being left to stand in dry air. Proposed is a sulfide-based solid electrolyte compound for lithium ion batteries containing a crystal phase of the cubic argyrodite-type crystal structure and represented by a composition formula (1): LiPSCl, wherein x and y in the composition formula (1) satisfy 0.05≦y≦0.9 and −3.0x+1.8≦y≦−3.0x+5.7.
