Abstract : The investigation of semiconductor cathode materials for lithium batteries using organic electrolytes was continued. Results on n-type cadmium fluoride in a lithium perchlorate-propylene carbonate electrolyte suggested that an insoluble or slowly-dissolving film of lithium fluoride may have been the main cause of cathodic passivation. A potassium hexafluorophosphate electrolyte was less satisfactory. Highly conductive zinc fluoride was produced by exposing the molten salt to zinc vapor in the absence of air. Another phase of the program dealt with solution-controlled cathode processes, which may sometimes occur in parallel with those involving solid-state conduction. A theoretical analysis was developed for a thin-layer cathode system which serves as a battery electrode model and provides a new method for the experimental study of nonfaradaic dissolution kinetics.
