Development of a sealed bipolar Li-alloy/FeS sub 2 battery for electric vehicles
Rapid progress is being made in the development of a bipolar Li- alloy/FeS {sub 2} battery with molten LiCl-LiBr-KBr electrolyte and MgO powder separator. Such a battery would be operated at 400- 425{degree}C and is expected to attain high performance and long cycle life (>1000 cycles). An overcharge tolerant cell design safeguards the Li-alloys/FeS {sub 2} cells in the bipolar battery ad allows charge equalization with simple trickle charging. New ceramic materials have been developed for use as the peripheral hermetic seals required for electrolyte containment in bipolar cells. A stack of four bipolar Li-alloy/FeS {sub 2} cells with these seals has been operated for over 150 cycles. Projected performance for a prototype sealed bipolar Li-alloy/FeS {sub 2} battery is 191 Wh/kg specific energy and 500 W/kg peak specific power through 80% depth of discharge. Outstanding electric-vehicle performance can be expected from such a battery. 9 refs., 8 figs.
