Development of HWAM LixCoO2 Reserve Battery

Abstract

The Alliant Techsystems' development program for a reserve, Hand Emplaced Wide Area Munition (HWAM) Battery successfully demonstrated the capability of a lithium metal/lithium cobalt dioxide electrochemical system to meet the tactical needs of the HWAM. Extensive safety testing, as part of a developmental program, proved that internal and external short circuit abuses do nothing to change the benign behavior of the power source. Because of its reserve design, long term storage has no effect on the battery's readiness when called upon to supply power for HWAM Standby, Alert, and Launch modes. Fourteen ampere hours of reserve capacity, demonstrated in fully developed hermetic cell hardware, can be increased to above twenty ampere hours with small adjustments in volume. This production ready design demonstrated extensive safety, fresh power from reserve storage, and an affordable unit price in practical production quantities.
