Abstract
A main object of the present invention is to provide a sulfide solid electrolyte material having favorable ion conductivity and low reduction potential. The present invention solves the above-mentioned problem by providing a sulfide solid electrolyte material including an Melement (such as a Li element), an Melement (such as a Ge element, a Si element and a P element) and a S element, wherein the material has a peak at a position of 2θ=29.58°±0.50° in X-ray diffraction measurement using a CuKα line; and when a diffraction intensity at the peak of 2θ=29.58°±0.50° is regarded as Iand a diffraction intensity at a peak of 2θ=27.33°±0.50° is regarded as I, a value of I/Iis less than 0.50, and Mcontains at least P and Si.
