Influence of Bismuth(Ⅲ) in Sulfuric Acid Electrolyte on the Cathode Behavior of Lead-acid Battery
Abstract:
The influence of Bi3+ ions in sulfuric acid electrolyte on the cathode behavior of lead-acid battery has been investigated by cyclic voltammetry(CV), cathodic polarization and electrochemical impedance spectroscopy(EIS). The results demonstrated that bismuth ion can be deposited on the cathode surface in the course of charging, resulting in the decrease of both cathode hydrogen overpotential and discharge capacity. The deposition of bismuth ions due to ion displacement may also lead to a quick formation of PbSO4 film on the electrode surface. The thickened PbSO4 film might retard the migration of H+ and HSO4- ions, decreasing the self-discharge of battery at open potential.
