The use of the dense UP-FeS/sub 2/ electrode and the lower-melting LiCl-LiBr-KBr electrolyte has eliminated the capacity-loss problem of the Li-Al/FeS/sub 2/ system; with LiCl-KCl electrolyte, the cell would have lost 30% of its capacity in the first 200 cycles. At the same time, the cell performance has been increased significantly. Based on the improved performance, a 250-Ah monopolar cell is expected to achieve a specific energy of 175 Wh/kg at a 4-h rate and specific power of 200 W/kg at 80% DOD. An advanced bipolar battery design has a projected capability of 200 Wh/kg at a 1-h rate with 600 W/kg at 80% DOD, and a battery specifically designed for continuous high power output is projected to provide greater than 2000 W/kg. These bipolar batteries can be operated nearly isothermally because the unique entropic cooling of the upper-plateau FeS/sub 2/ discharge reaction cancels I/sup 2/R heating. The dense upper-plateau FeS/sub 2/ cell with its high performance and durability poses exciting possibilities for demanding battery applications such as electric vehicles, stationary energy storage, and satellites.
