摘要:
The present invention aims to provide a sulfide solid electrolyte material with favorable ion conductivity, in which charge and discharge efficiency may be inhibited from decreasing. The object is attained by providing a sulfide solid electrolyte material, comprising: a Li element; a P element; and a S element, characterized in that the material has a peak at a position of 2θ = 30.21° ± 0.50° in X-ray diffraction measurement using a CuKα ray, and the sulfide solid electrolyte material does not substantially comprise a metallic element belonging to the third group to the sixteenth group.

The problem of the present invention is to provide a sulfide solid electrolyte material having excellent ion conductivity. The present invention solves the problem by providing a sulfide solid electrolyte material comprising an M 1 element (such as a Li element), an M 2 element (such as a Ge element and a P element), and an S element; having a peak in a position of 2θ = 29.58°±0.50° in an X-ray diffraction measurement using a CuKα line; and having an I B /I A value of less than 0.50 when a diffraction intensity at the peak of 2θ = 29.58°±0.50° is represented by I A and a diffraction intensity at a peak of 2θ = 27.33°±0.50° is represented by I B .
