processes. Generally, these charge transfer-related steps entail interfacial processes including surface adsorption of solvated ions, surface transport to an insertion site and through a potential passivation layer, and desolvation of the ion prior to insertion (in the case of organic electrolytes). It is noteworthy that there are only two DRT signals in the midfrequency range when probing the pseudocapacitive potential region, regardless of particle size, whereas three signals are observed in the battery-like potential region. We hypothesize that this is related to the availability of different insertion sites in the pseudocapacitive intercalation region due to the increased d-spacing, as predicted in previous work, therefore reducing impedance posed by surface transport. Three high frequency signals (P5 -P7) are related to ohmic resistances of the electrochemical cell components (electrolyte and contact resistances) as well as impedance contribution of the reference electrode, which do not strongly vary across the different samples and potential regions. Thus, they are subsequently excluded from the discussion as they contain little information on the intercalation process itself.
