Abstract
Provided is a rechargeable metal halide battery with an anode; an electrolyte including (i) an oxidizing gas, (ii) a metal halide, and (iii) a heterocyclic compound solvent; and a current collector contacting the active cathode material. As the metal halide of the electrolyte acts as an active cathode material that can receive, store, and release metal ions during charging and discharging of the battery, the battery does not require a dedicated cathode. The lack of a dedicated cathode results in a rechargeable battery with high power density that is lightweight and inexpensive to make.
Claims12
A battery, comprising:
- (a) an anode;
- (b) an electrolyte, comprising:
- (i) a solvent comprising a heterocyclic compound, and (ii) a metal halide dissolved in the electrolyte, wherein the dissolved metal halide functions as an active cathode material for the battery;
- and
- (c) a current collector contacting the metal halide dissolved in the electrolyte,
- wherein the battery does not include a dedicated cathode material in addition to the metal halide dissolved in the electrolyte that functions as the active cathode material.
