Performance and safety of Li/MnO/sub 2/ pouch cell batteries

The US Army Communications and Electronics Command (CECOM) is developing high capacity primary Li/MnO/sub 2/ pouch cell batteries as man-portable power sources for the individual soldier. Flat wound prismatic configurations with laminated foil enclosures provide efficient utilization of available battery box space. Technology can deliver 16 Ah in cells that will replace 7 Ah Li/SO/sub 2/ D cells in the Army BA-X47 two cell battery pack. This paper presents performance and safety results of this developing technology in Army battery configurations and applications.
