I learned from reading this research article "Electrochemical Energy Storage: Questioning the Popular v/v1/2 Scan Rate Diagnosis in Cyclic Voltammetry" that the diffusion and capacitive contribution values in battery-type electrodes are not determined using DUNN's equation. However, I have seen numerous publications where the researcher computed the contribution using this equation. Could someone kindly assist me in finding the equation that is used to determine the capacitive contribution in case of battery type electrode?
