A cadmium-air cell has been developed that will deliver at least 500 deep discharge cycles without any significant loss in electrical capacity and without any decrease in closed circuit potential. However, after one years storage at room temperature, the cell becomes cathode limiting with a resulting 15 loss in electrical capacity and a large drop in cell potential. Cadmium poisoning of the air-cathode can be avoided by constructing the unit cells with washed dry charged cadmium anodes. A paper design of a 24 volt, 25 ampere-hour cadmium-air battery indicates the following characteristics 42 watthourspound 2.35 watthourscu in Price - about 500.00 0.0017 per watthour per cycle assuming 500 cycles.
