Abstract
A sulfide solid electrolyte material having high Li ion conductivity can be obtained by providing a method for producing a sulfide solid electrolyte material that has peaks at 2θ=20.2° and 2θ=23.6° in an X ray diffraction measurement using a CuKα ray, the method including steps of: an amorphizing step of obtaining sulfide glass by amorphization of a raw material composition that includes at least LiS, PS, LiI and LiBr and a heat treatment step of heating the sulfide glass at a temperature of 195° C. or higher.
