Aluminum-air research and development program. Summary report - FY 1982
The aluminum-air program in 1982 focused on the following research areas: (1) experimental investigation of alternative cell configurations, (2) testing of specific configurations in multicell stacks, (3) long-term testing of air-electrodes under simulated vehicle duty cycles, (4) determination of kinetic of aluminum trihydroxide crystallization under candidate battery operating conditions, and (5) studies of anode behavior of alloys containing minor impurities such as iron, manganese, gallium, and phosphorus. The major achievements of this work period were: (1) The operation of six-celled and two-cell stacks without degradation of performance compared to laboratory baseline cells. (2) Redesign of solution-side current collection grid and successful application to wedge-shaped cells on the engineering scale (600 cm/sup 2/); demonstration of ability of such cells for continuous anode feed and rapid refueling. (3) Fabrication and testing of air electrodes catalyzed with certain macrocylic complexes; extension of cycle life to above 1000 standard drive cycles using non-noble metal catalysts. (4) Determination of role of minor electrolyte additions and precipitated Al(OH)/sub 3/ on air electrode life. (5) Development of a comprehensive mathematical model of aluminum trihydroxide precipitation under battery conditions.
