Abstract
Models to describe the multiphase electrode structure of anodically oxidized lead/sulfuric acid solutions, have been quantitatively tested, modified, and elaborated in accordance with the experimental evidence. The current, during oxidation at constant potential in the region of lead dioxide formation, is shown to be controlled sequentially by at least three diffusion processes, followed by at least two electrocrystallization stages and further intervals of diffusion control. The natures and concentrations of the diffusing species are quantitatively characterized on the basis of kinetic and thermodynamic data.
