Material-deposition processes in the separator of Li-alloy/FeS2 thermal cells
Abstract
The deposition of Li2S and Fe in the separator layer of Li-alloy/FeS2 thermal cells during discharge was studied. The parameters having the most impact included: anode Li activity, catholyte treatment (fused vs. unfused, lithiated vs. unlithiated), and electrolyte composition. The quenched cells were subjected to detailed postmortem examination by optical microscopy to measure the distribution and amount of deposition products in the separator layer. Complementary examination of select cells was also conducted using scanning electron microscopy and energy dispersive spectroscopy.
