Few papers have been reported for systems with transient CVs at electrodes of arbitrary size, probably due to the difficulty of the numerical calculations with migration. In particular, Klymenko and Amatore pointed out that numerical calculations are difficult in cases where the reactant loses its charge (the product becomes zero-valent). However, our interest is in electrodeposition/dissolution reactions of metals, i.e. reactions in which the zero-valence is the product/reactant. Our goal is to investigate the influence of migration for metal electrodeposition/dissolution under conditions without supporting electrolyte.
