“…Thus, it has been used in industrial electrochemistry for several purposes: the active mass in batteries [1] or anodic material for oxygen/ozone evolution [2][3][4], wastewater treatment by electrooxidation of toxic pollutant [5,6] and electrosynthesis [7]. PbO 2 prepared electrochemically exhibits high electronic conductivity.…”

In this study, nanoscale PbO 2 was obtained by the hydrolysis reaction of Pb(CH 3 COO) 4 in an ethanol solution, and the conventional PbO 2 was prepared by the electrolytic oxidation of PbO powder in a H 2 SO 4 solution. The former PbO 2 was identified as single phase ¢-PbO 2 with the average crystallite size of about 12 nm that had an excellent electrochemical activity, whereas the latter one was a mixture of ¡-PbO 2 , ¢-PbO 2 and PbSO 4 of about 41 nm average size. A hybrid lead-acid battery cathode consisting of an inner layer of the conventional PbO 2 and an outer layer of the nanoscale PbO 2 was also manufactured. The average diameter of the pores in the hybrid cathode was smaller than that of the conventional cathode of the lead-acid battery, which was made from only the conventional PbO 2 . The mass change in the hybrid cathode during the dischargecharge cycle test was relatively high as compared to that of the conventional cathode. Moreover, the cycle tests clearly showed that the reversibility of the discharge-charge reaction was improved in the hybrid cathode since the electrode mass returned to zero even after repeated charge and discharge. As a result, the hybrid cathode was significantly better than the conventional cathode regarding both the current efficiency and the utilization factor of the active materials of the cathode during the discharge-charge reaction. These results may suggest the manufacturing of a novel lead-acid battery with a higher power density and higher capacity.

“…Although nano b-PbO 2 prepared by hydrolysis of Pb(CH 3 COO) 4 [4,5] showed a high discharge capacity, the hydrolytic precursor was too expensive on an industrial scale. As an alternative, the chemical oxidation of Pb(II) precursor was used to synthesize the nanosized a-PbO 2 and b-PbO 2 , which delivered an utilization ratio higher than 45% as the positive active materials of lead acid batteries [6].…”
