<p>A method and apparatus for providing electrical energy. The apparatus defines an electrochemical cell (10) having a lithium-containing anode (11) and an air cathode (12). Electrolyte solution (18) containing soluble oxygen is flowed into contact with one surface of the air cathode. The opposite surface of the air cathode is exposed to ambient atmosphere. A catalytic screen (13) is provided between the anode and cathode where the soluble oxygen is present in the electrolyte in the form of H2O2 for catalyzing decomposition of the H2O2 and the reaction between the H2O2 and the cathode ions. A pump (20) is provided for selectively controlling the rate of flow of the electrolyte, as desired. </p> |
