METHOD OF PRODUCING REGENERATED SULFIDE SOLID ELECTROLYTE MATERIAL, METHOD OF MANUFACTURING ELECTRODE BODY, AND METHOD OF MANUFACTURING REGENERATED ELECTRODE BODY

摘要

PROBLEM TO BE SOLVED: To provide a method of producing a regenerated sulfide solid electrolyte material by regenerating a PSstructure.SOLUTION: The method of producing a regenerated sulfide solid electrolyte material includes a preparation step for preparing a liquefied sulfide solid electrolyte material where a sulfide solid electrolyte material having Li, P and S and a PSstructure is liquefied by moisture, and a dry step for regenerating the PSstructure by performing vacuum drying of the liquefied sulfide solid electrolyte material.
