As we know glassy carbon could be used as the working electrode because it has large over potential, however, what are the methods (both theoretical and experimental) to calculate the overpotential of ANY electrode material, especially in battery application?
Dear Zahid,
Do LSV (Linear Scan Voltammetry) to measure the overpotential for certain reactions on the electrode surface. Also selection of potential range and sweep rate is important here which depend on the requirement and type of system under study. Thanks

Do you mean overpotential in an electrolytic cell or in a galvanic cell (voltaic cell)?
Overpotentials can measured with reference electrodes. The highest level of accuracy is with rotating disc electrodes
Thank you all for your kind answers, Yurii V Geletii Thanks for asking, I mean by this, the overpotential in battery during charging ( electrolytic cell ) and discharging ( galvanic cell ). Cheers
