Design of a rapidly rechargeable gas battery is disclosed. In one embodiment, a rapidly rechargeable gas battery is constructed of a plurality of high surface area, gas adsorbing electrodes and an electrolyte, wherein, during charging operation, gases are formed and adsorbed at the plurality of electrodes such that they generate an electrochemical potential for discharge of the cell formed by electrodes and electrolyte until the state-of-charge has become negligible (deep discharge). The rapidly rechargeable gas battery is designed such that it can withstand high charging current and a deep discharge without irreversible changes in the electrode materials.

Rapidly rechargeable battery

An electrochemical cell is provided which has a liquid anode. Preferably the liquid anode comprises molten salt and a fuel, which preferably has a significant elemental carbon content. The supply of fuel is preferably continuously replenished in the anode. Where the fuel contains or pyrolizes to elemental carbon, the reaction C+2O&#x2192;CO+4emay occur at the anode. The electrochemical cell preferably has a solid electrolyte, which may be yttrium stabilized zirconia (YSZ). The electrolyte is connected to a solid or liquid cathode, which is given a supply of an oxidizer such as air. An ion such as Opasses through the electrolyte. If Opasses through the electrolyte from the anode to the cathode, a possible reaction at the cathode may be O+4e&#x2192;2O. The electrochemical cell of the invention is preferably operated as a fuel cell, consuming fuel and producing electrical current.
