The performance of Pb-Cu binary alloys used in lead-acid batteries

摘要

In this paper, a series of Pb-Cu binary alloys with different copper content are synthesized and the electrochemical performance is investigated by electrochemical working station. Results show that the introduction of Cu to the pure lead alloy can reduce the hydrogen evolution potential, and the addition of Cu is beneficial for the formation of Pb (IV) oxide, which can increase the overall conductivity of the plate. Besides, the corrosion property testing also shows that the Pb-Cu alloys possess good anti-corrosion properties compared with pure lead.
