| Research Abstract |
A series of PbO_2 nanoparticles prepared by hydrolysis of lead acetate in various mixtures of water and alcohol were characterized, and the properties of the novel lead acid battery using the nanoparticles as the active materials for positive electrode were examined by discharge-charge cycling. All the nanoparticles, which were identified as β-PbO_2 single phase, ranged from about 9 to 13 nm in diameter. In comparison with the PbO_2 powder prepared by the conventional method in lead acid battery industry, namely the electrolytic oxidation of lead powder, the PbO_2 nanoparticles had remarkably high performance in both utilization of the active materials for positive electrode and the current efficiency during discharge-charge cycling
