It is important to note that while additional aspects of the interface, such as ion-surface interactions or ion-solvent interactions that influence the distribution of relative permittivity, could be incorporated into the model, these were not included to avoid unnecessary complexity. Although the distribution of resistance and capacitance across the interface is not the sole cause of CPE behavior, it provides a plausible explanation for the presence of CPE even in atomically flat blocking electrodes within the double-layer potential window.
