DEVELOPMENT OF THE ALUMINUM-AIR BATTERY FOR ELECTRIC VEHICLE APPLICATIONS

Current progress is reported concerning the development of hardware for the aluminum-air electric vehicle battery. The polarization curves of large-scale aluminum-air cells (0.1-m exp 2 anodes) have been replicated in rapidly-refuelable cells of subscale size (167-cm exp 2) which were constructed for stacking into multicell modules. Solution-side current colllection by a structure which makes point- or line contacts at the aluminum/electrolyte interface is described. The technique allows rapid anode addition, minimizes anode fabrication costs, and simplifies cell design. The possible application of solution-side current collection to wedge-shaped cells allowing continuous anode feed and full utilization is discussed. Life-cycle testing of air electrodes in candidate battery electrolytes is reported. Temperature and aluminate concentration transients are modeled using experimental rate data. Program structure, technical strategy, goals, and economic analysis are briefly discussed. (ERA citation 06:033492)
