Theoretical studies on the cyclic voltammograms of intercalation electrodereactions

The cyclic voltammgrams of intercalation electrode reactions usually show a large potential difference between the oxidation peak and the reduction pe ak. A very low potential sweep rate is often required in the cyclic voltamm etric measurement. On the basis of the thermodynamic equation and the charg e transfer kinetic equation of the intercalation electrode reactions, its c yclic voltammograms are treated theoretically. In the treatment, the effect s of such parameters as the thermodynamic parameter b, kinetic parameters D and k, potential sweep rate v, and the electrode resistance on the cyclic voltammograms are discussed. The features of the cyclic voltammograms are e xplained according to the theoretical calculation.
