Low Temperature, Chloroaluminate Thermal Cells.

Abstract

This report summarizes the results of single cell studies on thermal cells containing sodium tetrachloroaluminate electrolyte. The best performing cells delivered 100 Wh/kg at a lifetime of 143 minutes to 75% of initial closed circuit voltage. Such cells operated at 200 C at a current density of 15mA/sqcm. A limited photomicroscopy study revealed a reaction between the lithium alloy anode and separating electrolyte when the cell is stored at 80 C. MoO2CL2 and Et4N(MoCl6) were studied as possible alternate molybdenum cathodes, but these materials did not show promising performance. (Author)
