A Thermal Battery Based on the Reaction of Cadmium and Liquid Iodine

A thermal battery consisting of a cadmium anode, a solution of potassium iodide in liquid iodine, and an inert cathode was studied at 125°C. The solubilities of and as separate components and as mixtures in liquid iodine, the conductivities of these solutions, and their corrosion behavior toward cadmium were investigated. The conductivity of polycrystalline follows the expression in the range between 0° and 200°C. Current‐voltage dependence of the cell, efficiency and the importance of the formation of the complex salt are discussed. The cell exhibits a fairly flat discharge curve. It was not possible to recharge it. Corrosion of the cadmium anode was negligible at current densities above 35 ma/cm2.
