Compatibility and accelerated aging study for Li(Si)/FeS/sub 2/ thermally activated batteries
Thermally activated batteries using the lithium(silicon) iron disulfide (Li(Si)/FeS/sub 2/) electrochemical system are used in weapons having a required storage life of 25 years and high reliability. A review of known data revealed no information on the compatibility of Li(Si)/FeS/sub 2/ with the organic materials used in the system. One phase of this study addressed the compatibility question; a second phase produced accelerated-aging data on pairs of materials. In addition, a group of production batteries was aged and tested. Three aging temperatures were used during the one-year study. Gas analyses, electrical tests and mechanical tests were compared for control and aged samples. Two results, the depletion of oxygen and an increase in hydrogen in the compatibility and accelerated-aging samples, have stimulated additional studies. No unexpected or significant changes were observed in the electrical or mechanical properties of the organic materials. Calorific output and chloride ion content of heat pellets indicated no degradation with aging. Ignition sensitivity and burn rate measurements suggested no heat pellet degradation. Oxygen content in aged lithium(silicon) anodes remained within acceptable limits. Single-cell tests and battery test results showed no degradation with aging.
