Abstract
A method for producing a sulfide solid electrolyte including an argyrodite-type crystal structure includes: pulverizing and mixing raw materials with a pulverizer to prepare an intermediate containing a glass component, wherein the raw materials include lithium, phosphorus, sulfur, and chlorine; and heat-treating the intermediate at 360 to 500° C. A molar ratio of the chlorine to the phosphorus, c (CIP), of the raw materials is greater than 1.0 and 1.9 or less.
