Abstract
A sulfide solid electrolyte material includes Li, K, Si, P and S elements; a peak at 2θ=29.58°±0.50° and not having a peak at a position of 2θ=27.33°±0.50° in X-ray diffraction measurement using a CuKα ray, or when a diffraction intensity at the peak of 2θ=29.58°±0.50° is regarded as Iand a diffraction intensity at the peak of 2θ=27.33°±0.50° is regarded as Ihaving a peak at the position of 2θ=27.33°±0.50°, a value of I/Iis less than 1; a P element molar fraction (P/(Si+P)) to a Si element total and the P element satisfies 0.5≦P/(Si+P)≦0.7, and a K element molar fraction (K/(Li+K)) to a Li element total and the K element satisfies 0<K/(Li+K)≦0.1.
