Abstract
A main object of the present invention is to provide a solid electrolyte material with high Li ion conductivity and heat stability. To achieve the above object, the present invention provides a solid electrolyte material comprising a composition of Li3PS4-xOx (1≤x≤3), a crystal phase A having a peak at a position of 2θ=17.80°±0.50°, 25.80°±0.50° in X-ray diffraction measurement using a CuKα ray, and a crystal phase B having a peak at a position of 2θ=22.30°±0.50°, 23.14°±0.50°, 24.80°±0.50°, 33.88°±0.50°, 36.48°±0.50° in X-ray diffraction measurement using a CuKα ray.
