Abstract
A metal halide battery includes an intercalation anode, a cathode that includes a metal halide incorporated into an electrically conductive material, an oxidizing gas, and an electrolyte in contact with the intercalation anode, the cathode, and the oxidizing gas. The battery has a cycle life reaching 1000 cycles at a current density that enables the battery to charge within 10-15 minutes. Electrolytes that may be used in the metal halide batteries include (i) carbonate ester-based compounds with at least one ethyl group and an ion-conducting salt and/or (ii) at least one cyclic ester compound.
