All aqueous thermally-regenerative battery

Abstract

Provided are systems and methods for thermally-regenerative batteries that avoid solid metal dissolution and deposition reactions. A thermoelectrochemical system includes a reactor comprising first and second electrode compartments with a separator interposed between the first and second electrode compartments. The reactor further includes first and second electrodes disposed in the first and second electrode compartments, respectively. The first and second electrode compartments include first and second aqueous electrolyte solutions, respectively. The first electrode compartment, the second electrode compartment, or both include a thermally regenerative ligand and optionally a non-thermally regenerative ligand. The first and second aqueous electrolyte solutions exclude solid metal dissolution and deposition reactants. Also provided are methods of using the thermoelectrochemical systems provided herein.
