The general behavior of electrochemical impedance exhibits non-ideal capacitive characteristics at low frequencies and resistive behavior at high frequencies. At low frequencies, the capacitive response arises from the high time constants of the Helmholtz and compact layers, followed by a decreasing time constant in the diffusion layer. This results in a high CPE impedance at low frequencies. In this regime, the impedance contribution of layers with lower time constants is overshadowed by the dominant effect of the Helmholtz and compact layers, making their influence negligible in the total impedance. On the other hand, at high frequencies, the oscillation period becomes much shorter than the interfacial time constants, causing the interface to behave as a short circuit. As a result, its impedance becomes negligible compared to the bulk electrolyte resistance, which dominates the total impedance, leading to the observed resistive behavior at high frequencies.
