Abstract: The different contributions of the interfacial capacitance are identified in the case of passive materials or thin protective coatings deposited on the electrode surface. The method is based on a graphical analysis of the EIS results to determine both the passive‐film capacitance in the high‐frequency domain and the double‐layer capacitance in the low‐frequency domain. The proposed analysis is shown to be independent of the physicochemical origins of the frequency dispersion of the interfacial capacitances which results, from an analysis point of view of the experimental results, in the use of a constant‐phase element However, for a correct evaluation of the thin‐film properties such as its thickness, the high‐frequency data must be corrected for the double‐layer contribution. In particular, it is shown that if the double‐layer capacitance gives a frequency‐dispersed response, it is necessary to correct the high‐frequency part for the double‐layer constant‐phase elements. This is first demonstrated on synthetic data and then used for the determination of the thickness of thin oxide film formed on Al in neutral pH solution.
