Abstract
A sulfide solid electrolyte material contains glass ceramics that contains Li, A, X, and S, and has peaks at 2θ=20.2° and 23.6° in X-ray diffraction measurement with CuKα line. A is at least one kind of P, Si, Ge, Al, and B, and X is a halogen. A method for producing a sulfide solid electrolyte material includes amorphizing a raw material composition containing LiS, a sulfide of A, and LiX to synthesize sulfide glass, and heating the sulfide glass at a heat treatment temperature equal to or more than a crystallization temperature thereof to synthesize glass ceramics having peaks at 2θ=20.2° and 23.6° in X-ray diffraction measurement with CuKα line, in which a ratio of the LiX contained in the raw material composition and the heat treatment temperature are controlled to obtain the glass ceramics.
