Abstract

See full text

Sulfide solid electrolyte material with favorable ion conductivity, wherein charge and discharge efficiency is inhibited from decreasing. Solves problem by providing a sulfide solid electrolyte material including a Li element, Si element, P element, S element and O element, having peak at position of 2θ=29.58°±0.50° in X-ray diffraction measurement using CuKα ray, wherein sulfide solid electrolyte material does not have peak at position of 2θ=27.33°±0.50° in X-ray diffraction measurement using CuKα ray, or in case of having peak at position of 2θ=27.33°±0.50°, value of IB/IA is 1 or less when diffraction intensity at peak of 2θ=29.58°±0.50° is regarded as IA and diffraction intensity at peak of 2θ=27.33°±0.50° is regarded as IB; and wherein molar fraction of O element to total of S element and O element is larger than 0.2.
