A comprehensive model for cyclic voltammetric study of intercalation/de-intercalation process incorporating charge transfer, ion transport and thin layer phenomena

A comprehensive model involving intercalation, competitive background reaction and de-intercalation is described. The interaction step is modelled as simple irreversible charge transfer and charge transfer coupled with diffusion. The de-intercalation step is modeled as a thin-film process. Overall cyclic voltammetric (CV) responses under all these limiting conditions are also presented and discussed. The method is also used for comparing typical experimental CV responses reported in the literature. The method is found to be useful in comparing the intercalation processes under different experimental conditions and evaluating model parameters.
