Study of effect of tin on the electrochemical properties of cycled PbSn alloys of lead-acid battery

Abstract

Tin has a beneficial effect on the electrochemical properties of the corrosion film formed on PbSn grids by reducing its resistivity mainly on cycling of the battery. Binary alloys with different tin contents were subjected to several charge-discharge cycles between and vs. Electrode in solution at. The electrochemical properties of alloys in sulfuric acid solution were studied by Cyclic Voltammetry, Linear Voltammetry and Chronpotentiometry. The compositions of the corrosion layer obtained at different numbers of cycles were determined by DRX. We were found that reduces the thickness and favorites a more conductive and dense layer between the grid and the positive active mass.
