Abstract
A rechargeable energy cell providing a thermal energy output during discharge, and which recharges electrically. The cell contains chemical reactants and reactant product. The reactants are controllably combined in a reaction portion of the cell to produce the reactant product and the thermal energy output. In the preferred embodiment, the reaction portion is designed to facilitate heat transfer. The reactant product is electrolyzed into the reactants, which are separated and stored in the cell, by at least one electrode in operational communication with the reactant product. The electrode has a hollow internal cavity, and a portion of the electrode functions as a valve to convey one of the reactants electrolyzed by the electrode into the cavity without conveying the reactant product into the cavity. The system is fully reversible and results in energy densities which are over 1 kilowatt-hour per Kilogram of cell weight. The cell is also capable of extremely high specific power rates of over 2 kilowatts per Kilogram.
