DEVELOPMENT OF THE HIGH RATE METAL-AIR DEPOLARIZED BATTERIES

Abstract

The investigation of the magnesium anode included a study of several electrolytes to determine compatibility with both electrodes. In all cases, best performance was obtained in a 'free' electrolyte system. The magnesium-air test cells, used only for exploratory studies, delivered specific energies of 50-55 Watt-hrs./lb. The investigation of calcium, aluminum, and barium air systems is still in an early exploratory stage. Particular interest however, is being given to calcium in an organic-aqueous electrolyte with various corrosion inhibiting agents. Heat transfer by means of air convection was studied over the entire temperature range (-25 to +120F) for the 2C through the C/50 rate of discharge. The testing units employed the zinc-air couple, but the heat transfer and air convection data are suitable for any metal-air battery design. This experimental investigation also indicated that low temperature bootstrap heating operation will be feasible for a zinc-air battery.
