Abstract
The model presented involves the autocatalytic step 
and the adsorption at the interface of three species, hydrogen, an anion, and the Zn2+ cation which can be complexed. The model is compared with results obtained, after eliminating the influence of convective diffusion, during the electrocrystallization of zinc in: (i) an acid sulfate solution, (ii) a Leclanché cell electrolyte, and (iii) an alkaline zincate solution commonly used in accumulators. The experimental results are in good agreement with the model, although the three electrolytes are markedly different. The model accounts indeed for the variation of the electrocrystallization efficiency with the current, for the appearance of multiple steady states revealed by S‐shaped current‐potential curves, and for the existence of an inductive faradaic impedance characterized by at least three time‐constants.
