A theoretical model for electrochemical cells formed with lithium anodes and halogen/charge-transfer-complex (CTC) cathodes is proposed. The electrolyte, the corresponding lithium halide, is initially formed in situ, and is added as a product of the electrochemical reaction. Current limitation due to lithium self-diffusion in the anode is considered. Calculations for the internal resistance of these cells are given for bromine-CTC cathodes assuming a crystalline solid-layer LiBr electrolyte. Calculations for self-discharge due to atomic bromine diffusion through the electrolyte to the anode are also presented. The actual state of the LiBr electrolyte is explained with recent scanning electron micrographs. Predictions of the theoretical model are compared to discharge data and to recent microcalorimetric self-discharge measurements. 15 refs.
