Abstract
A light weight, thermal battery having a cathode, an anode and a solid complex of SO2 and lithium tetrachloroaluminate as the solid electrolyte therein. The solid complex of SO2 and lithium tetrachloroaluminate is represented by the formula LiAlCl4·xSO2, wherein 1.0<x<4. The thermal battery is activated by heating the battery to temperatures of approximately between 35° C. to 90° C. A method of making the thermal battery is taught.
