Operations require batteries with capacities of 12 Ah over the temperature range from �V40,aC to 55,aC and storage stability from �V51.1,aC to 71,aC in a volume of 14 in3 and weight of 0.7 pounds. High capacity LiCFx batteries can meet these requirements if low temperature performance can be addressed. In this project we will develop LiCFx batteries with a novel solid electrolyte material that will replace the electrolyte and separator with a material that is both thermally stable at high temperatures and has excellent low temperature conductivity, a combination of traits that has eluded other solid electrolytes to date. TDA��s solid electrolyte is based on a self-assembled polymer that contains Li-ion channels with impressive ionic conductivity over a broad temperature range. Benefits: The benefits of the proposed technology include a wider storage and operating temperature range, which is the key for this program. LiCFx batteries would also allow for a significant increase in energy density, and therefore be able to meet the reduced size and weight requirements for the JTRS Handheld Manpack program. Return
