Electrochemical investigation of the anodic corrosion of Pb-Ca-Sn-Li grid alloy in H2SO4 solution

Abstract

The steady-state and anodic corrosion of Pb-0.17 wt.% Ca-0.88 wt.% Sn, and Pb-0.17 wt.% Ca-0.88 wt.% Sn-0.06 wt.% Li alloys in 4.5 M H2SO4 at 25 °C were studied using cyclic voltammetry, linear sweep voltammetry, and electrochemical impedance spectroscopy. The experimental results show that the lithium added to Pb-Ca-Sn alloy increases corrosion resistance in equilibrium potential and inhibits the growth of the anodic corrosion layer. © 2006 Elsevier B.V.
