✦ Synopsis

Impedance measurements have been made on Ll/SO, (C) cells (manufactured by a U.K. Company) at various states of charge. The mdwidual electrode impedances have been measured agamst a lithium reference electrode using a transfer function analyser. A model for the cathode behaviour is presented. From the values of the analogue circuit elements it is shown that there is a film on the undischarged cathode which mitially impaus the behaviour. Over a large range of residual capacities the charge transfer resistance is relatively constant. There is evidence for the presence of adsorbed mtermediates at the carbon matrix.
