Abstract
An electrochemical method and apparatus for high-amperage electrical energy storage features a high-temperature, all-liquid chemistry. The reaction products created during charging remain part of the electrodes during storage for discharge on demand. In a simultaneous ambipolar electrodeposition cell, a reaction compound is electrolyzed to effect transfer from an external power source; the electrode elements are electrodissolved during discharge.
