Abstract
Methods for recycling solid electrolytes include contacting the solid electrolyte with a metal halide in a solvent to produce a mixture comprising a metal sulfide, an alkali metal salt, and undissolved material. The undissolved material is removed from the mixture to form a solution, and then the solvent is removed to form a composite that includes a metal sulfide and an alkali metal salt.
