Thin-cell technology for Li(Si)/FeS/sub 2/ thermal batteries
Sandia National Laboratories (SNL) has been developing Li(Si)/FeS/sub 2/ thermal batteries for several years as an alternative to the older Ca/CaCrO/sub 4/ system. Batteries made with Li(Si)/FeS/sub 2/ have proven to be more predictable, more reliable, more capable, and more forgiving than those using the older system. Since the voltage per cell for Ca/CaCrO/sub 4/ is about 0.5 V higher than that for Li(Si)/FeS/sub 2/, the new system requires more cells to obtain a specified voltage. Furthermore, unlike the Ca/CaCrO/sub 4/ technology, a cell in the new technology must incorporate a separator layer. Consequently, it has become necessary to develop a thin-cell technology for Li(Si)/FeS/sub 2/ thermal batteries in order to replace Ca/CaCrO/sub 4/ in applications that require small batteries. A current program to develop such a technology is summarized and battery-discharge data representative of the most recent advances are given. Although the major effort has involved Li(Si) alloy as the anode, some preliminary work has been done with Li(Al). (WHK)
