Solid Electrolytes with Wide Temperature Operating Range for LiCFx Batteries

This SBIR Phase I project seeks to develop thermally stable high-energy LiCFx batteries to satisfy mission operational temperature requirements of the Joint Tactical Radio System (JTSR) Handheld Manpack. 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.
