Abstract : The program has been directed toward the development of a prototype rechargeable metal-air battery for use as a power source for portable military communications equipment. Zinc, lead, and cadmium anode systems have been considered on a competitive basis so that one of the three anode systems would be included in a prototype metal-air battery. An air electrode system as operating in alkaline electrolytes with zinc or cadmium anodes has been investigated. Lead in an acid electrolyte has also been investigated with an air cathode and with a redox cathode. Design goals for the prototype battery include 500 continuous cycles at a discharge rate of C/5 with energy densities of 25 watt hours per pound at -40 deg F and 50 watt hours per pound at 80 deg F. Cell life is considered terminated when a given cell delivers less than 60 percent of its rated capacity. (Author)
