Abstract: Provided is a method for producing sulfide solid electrolyte having an argyrodite-type crystal structure, the method including mixing lithium sulfide, a phosphorus sulfide, and an ammonium halide to produce a solid electrolyte precursor, and firing the solid electrolyte precursor. The method for producing a sulfide solid electrolyte having an argyrodite-type crystal structure provides a method for easily producing a high-quality sulfide solid electrolyte without using an elemental halogen which complicates the handling or a lithium halide which has a considerably high hygroscopicity.

Abstract: [Problem] To provide a method for efficiently producing a sulfide solid electrolyte using a liquid-phase method.
[Solution to Problem] A method for producing a sulfide solid electrolyte not using a pulverizer in reacting raw materials, wherein a raw material that contains lithium sulfide, a phosphorus compound and a halogen compound, and a complexing agent are stirred in a reactor while a fluid that contains the contents in the reactor is discharged outside the reactor through a discharging port arranged in the reactor and the fluid that contains the discharged contents is returned back to the reactor through a returning port arranged in the reactor to thereby make the contents-containing fluid circulate therethrough.
