Our model predict that in the transition region between low and high frequencies, the diffusion layer time constant falls within a range where the distribution of time constants significantly influences the impedance transition. This intermediate frequency range marks the gradual shift from capacitive to resistive behavior, governed by the interplay between interfacial ion dynamics. The nature of this transition is highly dependent on ion properties such as ionic radius, hydration shell radii, and mobility, which dictate how ions respond to the applied AC perturbation.
