Abstract

According to one embodiment, there is provided a method for producing an LGPS-type solid electrolyte, comprising: allowing a first solution, in which a first compound comprising, as a counter ion, a monovalent or divalent metal atom M1 ion having an ionic radius larger than that of a Li atom, or an ammonium ion, is dissolved in a solvent, to come into contact with a cation exchange resin comprising a Li ion, so that the M1 ion or the ammonium ion comprised in the first compound is exchanged with the Li ion, thereby obtaining a second solution, in which a Li-containing compound is dissolved in the solvent, removing the solvent from the second solution to obtain Li-containing crystals, mixing the Li-containing crystals with Li<3>PS<4> crystals to obtain a precursor, and treating the precursor by heating, wherein the first compound consists of the M1 ion or the ammonium ion and an anion containing an S element and an Sn element.
