Abstract

Studies of the composition of the interfaces in the anode and cathode regions of lithium alloy/metal sulfide battery systems should lead to a clearer understanding of overall battery performance. Using techniques developed for studies of other active metals and their oxides, a study was made of these critical interfaces in order to correlate the results to battery performance data. The electrochemical system of interest for the thermally-activated batteries consists of a lithium alloy anode, a potassium chloride-lithium chloride electrolyte with binder material, and an iron disulfide cathode material. The results of studies by electron and photomicroscopy, electron microprobe (EM) analysis, Auger electron spectroscopy (AES), and X-ray photoelectron spectroscopy (XPS) for the anode/electrolyte-binder (EB) interface and the cathode/electrolyte-binder interface are discussed. The results are outlined according to the two active electrochemical components for various states of discharge.
