Abstract : The electroformation and discharge of lithium and copper chloride in 1M LiAlCl4 in propylene carbonate was investigated to evaluate the lithium-copper chloride high energy density battery system. The utilization efficiency of lithium depended on the substrate, the current density and the loading. The operation of a rechargeable cupric chloride electrode is possible under suitable conditions. Impurities present in solution caused a significant self-discharge of lithium and increased the coppper salt solubility. The formation of highly soluble chloro-cuprate complexes of copper salts during discharge was found to be the principal mechanism resulting in loss of cathode efficiency. (Author)
