The electrochemical properties of the interface between graphite sample and electrolyte solution will change during the anodic intercalation process. The physical quantities which indicate these electrochemical properties can be calculated from the results of the AC impedance measurements. An equivalent circuit is suggested for the calculation. The results of this method are in very good agreement with those from other methods, therefore it is very helpful for studying the kinetics of the anodic intercalation process into graphite in the electrolyte solution.
