Abstract
Aimed at providing a sulfide solid electrolyte comprising an argyrodite type crystal structure, having a high ionic conductivity due to presence of a large amount of a halogen element and is capable of suppressing agglomeration at the time of production. Provided is a sulfide solid electrolyte comprising lithium, phosphorus, sulfur and one or more elements X selected from halogen elements, wherein the sulfide solid electrolyte comprises an argyrodite type crystal structure, and wherein a molar ratio of the lithium to the phosphorus 'a (Li/P)', a molar ratio of the sulfur to the phosphorus 'b (S/P)' and a molar ratio of the element X to the phosphorus “c (X/P)” satisfy the following formulas (1) to (3):5.0≤<7.3  (1)0.70≤<1.0  (2)7.0<≤7.3  (3)provided that b>0 and c>0.
