Impedance Spectroscopy: A Method for In-situ Characterization of Corrosion in Lead-Acid Battery
The composition and properties of the corrosion layer of Pb-1.3-3.5 wt.% Sb alloys in 0.5 M sulphuric acid have been studied as a function of potential in the potential range between hydrogen and oxygen evolution by means of cyclic voltammetry and impedance spectroscopy. It has been found that antimony influences considerably the electrochemical behavior of lead in the wider potential range. This influence is especially important in the lead oxide potential range, where antimony facilitates formation of non-stoichiometric oxides, PbO_n and Pb_(1-x)Sn_xO_n, while it retards the formation of PbO_2 in the corrosion layer. Since mixed oxides are better conductors, antimony in alloy considerably changes the layer resistance in the potential range where the positive plate operates in the acid battery.
