Abstract:

As a consequence of the experimental work that has been carried out to evaluate the lead-air, the cadmium-air, and the zinc-air secondary battery systems, it has been determined that major emphasis would be focused on the cadmium-air battery development. Cadmium-air cells have been prepared and these cells have been tested and have shown 200 cycles of operation. Although a partial loss of capacity does occur on cycling, this can in part be restored by the appropriate choice of the charge regime. Work on the zinc-air system has been curtailed for very high rate applications. Some of the zinc-air effort has been redirected toward the development of a 5 hour discharge rate cell. It is planned that the cadmium-air and zinc-air systems will be compared with respect to their performance characteristics based on the five hour discharge rate type of service. Efforts will be made to ascertain the cycle life of the five hour discharge rated zinc-air cell. Author
