摘要

Lead acid battery is the most preferential option for energy storage application because of its maturemanufacturing technology, reliability and high safety. Nonetheless, a negative trait is that the lead–calcium (Pb–Ca) alloy may suffer severe corrosion as a result of long-term depth discharge. Herein,corrosion resistance property has been implemented by cyclic voltammetry (CV) approach and theconcentration of Pb2+ in the mixture solution (acetic acid, nitric acid and hydrogen peroxide) aremeasured for the first time by inductively coupled plasma atomic emission spectrometry (ICP-AES)after corrosion test. The addition of the lanthanum (La) and barium (Ba) can improve the corrosionresistance of Pb-Ca-Sn-Al alloy in sulfuric acid electrolyte. Furthermore, the outstandingly highconductivity of the oxidation film on aforementioned alloy electrode is achieved because the growth ofPbO in the oxidation film is inhibited by the La or Ba in Pb-Ca-Sn-Al alloy. Meanwhile, the additionof La or Ba can improve oxygen evolution performance of alloy electrodes in sulfuric acid electrolyte.
