Abstract :
The development of two Li/SOCl2 pulse batteries is presented. The BA-6516 battery contains eight small 2/3 A cells connected in series. It was required to operate under a 1.5 A pulse load. The BA-6699 battery is similarly composed of eight large DD cells. The pulse load on this battery was 20 A with a 3.2 A background. The major design features of the batteries are described. The performance was optimized through selection of cell surface areas, internal construction, and component substrates. High surface area carbons produced superior cold temperature load voltage. An ethylene tetrafluoroethylene (ETFE) separator was used exclusively in the cells to ensure integrity of the spirally wound element and allow increased cell surface area. The advantages and disadvantages to the practical use of ETFE are discussed. The performance results and safety relative to vent selection are considered
