| Abstract: | The influence of Bi 3+ 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 PbSO 4 film on the electrode surface. The thickened PbSO 4 film might retard the migration of H + and HSO - 4 ions, decreasing the self discharge of battery at open potential. |
