The use of cupric chloride as a cathode additive in lithium-thionyl chloride cells was investigated. Carbon black paste microelectrodes containing 21.7 weight percent of cupric chloride were used to study the effect of cupric chloride additive on cyclic voltammograms, polarization curves and cathode potential during discharge. It was found that the incorporation of cupric chloride in the carbon black cathode structure resulted in lowering of the cathode polarization so that carbon black cathode containing the additive showed higher cathode voltages than the carbon black cathodes without the additive. Cyclic voltammetry at these microelectrodes also showed that the thionyl chloride reduction peak was also shifted to more positive potentials in the cyclic voltammograms. Author
