Improved Cathode Systems for High-Energy Primary Batteries,

Abstract

This research is concerned with the influence of electronic conductivity on the performance of high-energy battery cathode systems. Because of its availability as an n-type semi-conductor, cadmium fluoride was chosen as a model cathode system for the initial study. Yttrium-doped cadmium-treated cadmium fluoride was discharged with 43% utilization at 2 ma/sq cm in a lithium perchlorate-propylene carbonate electrolyte, while the corresponding utilization efficiency for the undoped material was not more than 10%. The electrochemical results were obtained with conventional powered cathode mixtures containing 20% carbon black. In solid state conductivity measurements it was found that pressure contacts, including those of carbon, did not produce ohmic electrical connections to cadmium fluoride.
