Abstract
An object of the present invention is to provide a sulfide solid electrolyte material with favorable ion conductivity. In the present invention, the above object is achieved by providing a sulfide solid electrolyte material comprising a composition of LiSiPSX(0.37≤x≤0.40, 0.054≤y≤0.078, 0.05≤z≤0.07, 0≤w≤0.05, and X is at least one of F, Cl, Br, and I), characterized in that the sulfide solid electrolyte material has a crystal phase A having a peak at a position of 2θ=29.58°±1.00° in X-ray diffraction measurement using a CuKα ray, the sulfide solid electrolyte material does not have a crystal phase B having a peak at a position of 2θ=30.12°±1.00° in X-ray diffraction measurement using a CuKα ray, or slightly has the crystal phase B.
