Performance of LiAlloy/Ag(2)CrO(4) Couples in Molten CsBr-LiBr-KBr Eutectic

Creators

Description

The performance of Li-alloy/CsBr-LiBr-KBr/Ag(sub 2)CrO(sub 4) systems was studied over a temperature range of 250 C to 300 C, for possible use as a power source for geothermal borehole applications. Single cells were discharged at current densities of 15.8 and 32.6 mA/cm(sup 2) using Li-Si and Li-Al anodes. When tested in 5-cell batteries, the Li-Si/CsBr-LiBr-KBr/Ag(sub 2)CrO(sub 4) system exhibited thermal runaway. Thermal analytical tests showed that the Ag(sub 2)CrO(sub 4) cathode reacted exothermically with the electrolyte on activation. Consequently, this system would not be practical for the envisioned geothermal borehole applications
