Abstract

In an embodiment, a metal or metal-ion battery cell, includes anode and cathode electrodes, a separator electrically separating the anode and the cathode, and a solid electrolyte ionically coupling the anode and the cathode, wherein the solid electrolyte comprises a material having one or more rearrangeable chalcogen-metal-hydrogen groups that are configured to transport at least one metal-ion or metal-ion mixture through the solid electrolyte, wherein the solid electrolyte exhibits a melting point below about 350° C. In an example, the solid electrolyte may be produced by mixing different dry metal-ion compositions together, arranging the mixture inside of a mold, and heating the mixture while arranged inside of the mold at least to a melting point (e.g., below about 350° C.) of the mixture so as to produce a material comprising one or more rearrangeable chalcogen-metal-hydrogen groups.
