Abstract

The electrochemical behaviour of Pb-(0–8%) Sb alloys in H2SO4 solutions was studied using impedance and cyclic galvanostatic measurements. The experimental results indicated that the alloy containing 2.5% Sb is critical in many respects. The potential arrest corresponding to the formation of the sulphate layer was absent for the alloy containing 2.5% Sb while it was present for the other alloys. The efficiency of the charging was found to increase with decreasing anodizing current. The electrochemical transformations during cyclic galvanostatic polarization and self-discharge are discussed.
