Advanced batteries for electric vehicles
Over the past twenty years, some of the most difficult problems have been solved in the development of long-lived lithium/sulfide secondary batteries having molten chloride electrolytes. Recent tests of Li-Al/FeS/sub 2/ cells have demonstrated 1000 cycles of operation and the practicality of achieving a specific energy of 175 Wh/kg for prismatic cells. Bipolar cells now under study may achieve even higher specific energy. Also, bipolar cells make possible the use of low-cost coated current collectors for the positive electrode instead of the expensive molybdenum current collectors that have been required for prismatic cells. Very compact batteries to power an electric van have been conceptually designed with this approach. These batteries would provide a range for the loaded vehicle of more than 100 miles for a battery weighing 280 kg, only 15% of the loaded vehicle weight (1930 kg). 16 refs., 5 figs., 5 tabs.
