Effect of indium alloying with lead together with the addition of phosphoric acid in electrolyte to improve lead-acid battery performance
The electrochemical and corrosion behavior of Pb and Pb-In alloys in both phosphoric and sulfuric acid solutions containing various concentrations of phosphoric acid (0.05 to 0.20 M) at different temperatures was studied. Tafel plot and electrochemical impedance spectroscopy (EIS) techniques were used to obtain the experimental data, and the corrosion products formed on the surface were characterized by scanning electron ...
