SULFIDE SOLID ELECTROLYTE MATERIAL, BATTERY, AND METHOD FOR PRODUCING SULFIDE SOLID ELECTROLYTE MATERIAL

摘要

An object of the present invention is to provide a sulfide solid electrolyte material having satisfactory ion conductivity. In the present invention, the above object is solved by providing a sulfide solid electrolyte material comprising a Li element, a Si element, a P element, a S element, and an X element (in which X represents at least one of F, Cl, Br and I), the sulfide solid electrolyte material having a crystal phase B having a peak at the position of 2θ=30.12°±1.00° measured by X-ray diffractometry using CuKα ray.
