Compatability and accelerated aging study for Li(Si)/FeS/sub 2/ thermally activated batteries
Thermally activated batteries using the Li(Si)/FeS/sub 2/ system are being developed by Sandia National Laboratories. These components are used in systems which require a storage life of 25 years and high reliability. A previous aging study was completed on this system, but no organic materials other than those in the electrical match and heat paper fuse strips were included. The present study incorporates all of the materials in the system, both organic and inorganic, except for the electric match and heat paper. There are two main parts in this study: (1) a compatability study in which the four organic materials under investigation are placed in a hermetically sealed stainless steel container with battery components; (2) an aging study of pairs of material and individual materials in which one organic material is placed in a hermetically sealed stainless steel container with battery components. The compatibility study examines effects of some materials upon others (outgassing, etc.) which would cause degradation and/or functional failure. The compatibility materials in this study were aged at 75/sup 0/C. The aging study uses three temperatures (75, 65, and 55/sup 0/C) to span activation energies and utilizes failure mode testing related to aging effects. Testing intervals are two, four, eight, and twelve months. Data from the two studies can be correlated and lifetime predictions are possible.
