Abstract
A method of producing a sulfide solid electrolyte material includes: forming an intermediate having crosslinking sulfur but no LiS, by vitrifying, in a first vitrification process, a starting material composition obtained by mixing LiS and a sulfide of a group 14 or group 15 element such that a proportion of LiS with respect to the sum total of the LiS and the sulfide of a group 14 or group 15 element is smaller than a proportion of LiS required for the sulfide solid electrolyte material to obtain an ortho composition; and eliminating the crosslinking sulfur by vitrifying, in a second vitrification process, an intermediate-containing composition resulting from mixing a bond cleaving compound, which cleaves a bond of the crosslinking sulfur, with the intermediate.
