Abstract

The effect of BaS04 and commercial lignin as additive, individually and in combination, on the performance of the negative plate of a lead acid battery was studied in sulfuric acid medium by cyclic voUammetry. The cyclic voltammograms were analysed to study the oxidation-reduction reaction of the negative plate. The results showed that the beneficial effect of BaS04 and tbe lignin sample on the discharge reaction of the lead e,lectrode was as expected. The results indicate a dissolution-precipitation mecbanism operating in the passivation of lead in sulfuric acid electrolyte. A concentration of 30 ppm of tbe lignin sample in sulfuric acid was found to be the optimum amount in temlS of the negative plate performance.
