Abstract
An object of the present invention is to provide a sulfide solid electrolyte material having satisfactory ion conductivity. The present invention attains the object by providing a sulfide solid electrolyte material comprising a Li element, a Ge element, a P element, a S element, and an X element (X is at least one of F, Cl, Br and I), wherein the sulfide solid electrolyte material comprises a crystal phase A having a peak at the position of 2θ=29.58°±1.00° measured by X-ray diffractometry using CuKα ray, has a composition of y(LiX)·(100−y) (Li3.35Ge0.35P0.65S4) (y satisfies the relationship: 0<y<20), and the sulfide solid electrolyte material does not comprise a crystal phase B having a peak at the position of 2θ=25.20°±1.00° measured by X-ray diffractometry using CuKα ray.
