Abstract
A rechargeable metal halide battery with an optimized active cathode electrolyte solution has high energy density and does not require charging following fabrication. The optimized active cathode electrolyte solution includes (i) a mixture of a metal halide and its corresponding halogen dissolved in an organic solvent at a concentration ratio greater than 0.5 and (ii) an oxidizing gas. The organic solvent is a nitrile-based compound and/or a heterocyclic compound. Glyme may be added to the organic solvent to improve battery performance.
