Abstract : Studies of the aluminum/oxygen battery system were conducted in three areas; (1) the anodic behavior of aluminum in KOH, (2) full cell assembly and performance verification, (3) system analysis. Aluminum alloy 44836 made by Olin was found to give the most cathodic potentials to date both at open circuit and during discharge but still with hydrogen evolution. Aluminum/oxygen cells at various electrolyte spacing, anode thicknesses, and discharge rates were evaluated: Olin alloy 12226 was used for these experiments. Overheating of the cells during discharge was observed. Zinc/oxygen cells were tested to verify cell design. Good reproducibility was obtained. The zinc/oxygen and aluminum/oxygen battery systems were analyzed with respect to weight, volume, and waste heat generation. A technique to achieve optimum size of electrodes and current collectors was developed. System analysis has shown that for a high rate application the most significant battery weight controlling factor is the cell voltage. Other parameters such as irreversibility also contribute significantly to the battery weight. (Author)
