The cyclic voltammgrams of intercalation electrode reactions usually showa large potential difference between the oxidation peak and the reduction peak. A very low potential sweep rate is often required in the cyclic voltammetric measurement. On the basis of the thermodynamic equation and the charge transfer kinetic equation of the intercalation electrode reactions, its cyclic voltammograms are treated theoretically. In the treatment, the effects of such parameters as the thermodynamic parameter b , kinetic parameters D and k, potential sweep rate u, and the electrode resistance on the cyclic voltammograms are discussed. The features of the cyclic voltammograms are explained according to the theoretical calculation.
