PROBLEM TO BE SOLVED: To provide a recovery method of sulfide solid electrolyte capable of recovering the Li ion conduction performance.SOLUTION: A recovery method of sulfide solid electrolyte includes a step for removing the moisture adhering to a glass ceramic sulfide electrolyte having diffraction peaks at Bragg angles (2&thetas;±0.50) of 20.2°, 23.6°, 41° in X-ray diffraction measurement using CuKα ray, or to a crystallization sulfide solid electrolyte having a diffraction peak at 29.5°, by heating. |
