SBIR-STTR Award

A research program to improve the performance of polymer electrolyte-based Li ion batteries is proposed. The cell will use a proprietary electrolyte, a high capacity insertion cathode and a high capacity intercalation anode. The major emphasis in Phase I will be to identify polymer electrolytes which will meet NASA's requirement of operating in low temperatures down to -60 degree Celsius. The cell will have high rate capability and a cycle-life of over 1000 cycles. The use of the high capacity cathode will increase the specific energy of the cell to >170 Wh/kg and volumetric energy density of about 310 Wh/l.
