The Al-air battery is being developed to provide an electric vehicle with conventional automobile performance. A rapidly-refuelable, 6-cell battery (200-cm/sup 2/ electrodes) was evaluated. RX-808 aluminum anodes and air cathodes were used with a flowing alkaline electrolyte. Peak power was found to increase with temperature, decrease with aluminate concentration and be unaffected by electrolyte flow. The best performance was 5.28 kW/m/sup 2/ peak power density, 2.08 kWh/kg Al energy density and 80% coulombic efficiency. Anode refueling is rapid and 100% utilization is achieved. Additional evaluation included cathode catalysts, a thermal balance and monitoring electrolyte composition.
