The kinetics of PbSO/sub 4//PbO/sub 2/ on Pb-Ca-Sn-Al grid alloys with bismuth additions at different temperature

Potentiodynamic measurements have been employed to study the electrooxidation-reduction reaction of PbSO/sub 4//PbO/sub 2/ on a common lead-calcium-tin-aluminum grid alloy in sulfuric acid solution from -10/spl deg/C to 50/spl deg/C. The logarithm of the peak current density of the electro-oxidation reduction of PbSO/sub 4//PbO/sub 2/ vs. The reciprocal of absolute test temperature has been plotted and presented in Arrhenius form. The effect of alloying with bismuth upon the electrochemical behaviors, in particularly the changes in the kinetics parameters as the electrodes were cycled at different temperature, have been examined.
