Abstract (en)

[origin: EP2555307A1] 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 2¸ = 29.58°±0.50° in an X-ray diffraction measurement using a CuK± line; and having an I B /I A value of less than 0.50 when a diffraction intensity at the peak of 2¸ = 29.58°±0.50° is represented by I A and a diffraction intensity at a peak of 2¸ = 27.33°±0.50° is represented by I B .
