Influence of phosphoric acid on the grid alloys of positive plates in the lead acid battery system: A comparative study
The effect of phosphoric acid in lead acid batteries was studied with potential sweep techniques. Lead-tin (2%) and lead-calcium (0.1%) tin (0.35%) alloys were used as the grids. The influence of phosphoric acid in the presence of tin, calcium and calcium alone on the grid were examined. Phosphoric acid inhibits the formation of beta-PbO2 in the alloys. (c) 2006 Elsevier B.V.
