. The approximated equation also shows that Δ𝜙 decreases almost linearly with 𝐸. In this study, to simplify the simulation, the calculations were carried out under conditions where both reactants/products are dissolved in solution. However, simulations are currently being carried out under conditions where the electrodeposition/dissolution reaction of the metal is used as the electrode reaction. It will follow the electrodeposition/dissolution reaction of Zn-anode.
