Sealed Lithium Inorganic Battery
Abstract
Studies were continued of the effects of hardware materials on the storage and discharge characteristics of Li/SOCl2 cells. Two effects were considered in particular: the ability of the hardware surface to carry the reduction of thionyl chloride when in contact with lithium (self discharge) and the corrosion of hardware materials resulting in the formation of soluble iron species and secondary iron deposits on the anode surface (anode passivation). The results are presented for 304 stainless steel showing a significant rate of self discharge due to the reduction of thionyl chloride and an insignificant influence of the hardware corrosion on the anode passivation on storage. The tests with Kovar showed so far a negligible rate of iron generation in the electrolyte, when the Kovar hardware components are in contact with either lithium or carbon electrode. The tests in progress should show soon if Kovar is any different from the other materials in reducing thionyl chloride (self discharge) during storage at various temperatures.
