A battery, comprising:
- (a) an anode that takes up metal ions from an electrolyte during charging, and releases the ions to the electrolyte during discharging, the electrolyte comprising:
- (i) a solvent comprising a heterocyclic compound, and
- (ii) a dissolved halide, wherein the halide functions as a cathode for the battery;
- (b) a solid electrolyte interphase (SEI) layer contacting the anode, the SEI layer including an oxide of the metal ions;
- and
- (c) a current collector comprising an electrically conductive porous material, wherein the current collector contacts the dissolved halide.
3 more elements
A method of forming a battery, comprising:
- dissolving a metal halide in a solvent, the solvent comprising a heterocyclic compound, thereby forming a solution;
- soaking a separator with the solution;
- stacking an anode, the separator soaked with the solution, and a current collector, wherein the stacking comprises placing the separator soaked with the solution between the anode and the current collector;
- and
- introducing an oxidizing gas to the stacked anode, the separator soaked with the solution, and the current collector to form the battery, wherein the battery comprises:
- an anode,
- an electrolyte, comprising:
- an oxidizing gas;
- an active cathode material comprising a metal halide;
- and
- a solvent comprising a heterocyclic compound;
- and
- a current collector contacting the cathode material.
