Sulfide solid electrolyte material, lithium solid-state battery, and method for producing sulfide solid electrolyte material

摘要

A sulfide solid electrolyte material contains glass ceramics that contains Li, A, X, and S, and has peaks at 2&thetas; = 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 Li
