High Energy Desnity, Ultra-safe, Li-Mn02 Pouch Cell

The Army is one of the major users of Li batteries, as they are reliable, have high energy density and shelf life. Present lithium systems are not safe and require special care and caution by the user. An Ultra-safe, high rate, high energy density Li/Mn02 cell packaged in soft pouch material is being proposed for development of BA-5590/U cell. This new system is safe, low cost and has potential to replace all of the present primary cells/batteries used by the Army. A phase I program to prove the feasibility of BA-5590/U cell with Li/Mn02 chemistry and U.B.I.'s patented safety separator, and package with a soft pouch material is proposed. During this progra, work will focus on hermetic sealing, manufacturing process and fabrication of high rate cathode. Also, assembled cells will be evaluated for electrical performance and safety. U.B.I is uniquely qualified to conduct this program, as we have in place manufacturing process necessary for manufacture of Li/Mn02 batteries and owns a safety-shutdown spearator process. During phase II, U.B.I. will fabricate BA-5590/U cells and assemble them in to a battery, then evaluate battery for electrical performance and prove use of Li/MN02 chemistry and soft pouch packaging material to replace present chemistry. An Ultra-safe, high rate, high energy density battery with low cost is desirable to Army to reduce thier cost without sacrificing safety, reliability and performance.
