A mathematical model for the porous lead dioxide electrode. II. The pseudo-steady state approach for low rates of discharge

摘要: A theoretical analysis of the discharge behaviour porous lead dioxide electrode at low current densities is made on basis a previously proposed model. The pseudo-steady state approach proves to be useful for rates discharge, while it fails rapid discharges. distribution becomes non-uniform during because concentration changes and decreasing porosity. maximum moves inwards into as result gradual insulation surface by sulphate crystals. At end slow material has been uniformly utilized along depth electrode, provided that porosity sufficiently high. If, however, initial less than about 50% inner parts may not always fully extensive plugging pores
