Properties and Application of Pb-Ca-Sn-Al-Ag-La-Ce Alloys for Positive Grids of Electric Vehicle Batteries
The influence of the mixed rare earth metal, Lathanum and cerium, as an alloying additive on the electrochemical behaviour was studied by means of self-depassivation, linear sweep voltammetry and a.c. impedance spectroscopy in 1.28g/m3 H2SO4 at 250C. Studies on Pb-Ca-Sn-Al-Ag-La-Ce alloys indicated the mixed La and Ce can refined crystal grains, inhibit the hydrogen evolution and oxygen evolution, and improve the corrosion-resistance performance. So the mixed La and Ce can prolong life of electric vehicle batteries.
