Electrochemical Perforance and Synthesis of Nanostructured Lead Oxide

Huiqi Wang


This paper describes a facial in situ synthesis method of nanostructured lead oxide powders. Lead oxide crystallites was reproducibly prepared by optimization of the temperature condition at 700?. The morphology, crystallization process, speci?c surface area and electrochemical performance of PbO was characteriazed by different analytical methods such as XRD, SEM, TEM, BET gas sorption speci?c surface area measurements and electrochemical tests . The XRD showed that the PbO is mixtures of α- and β- phases. TEM observations indicated exhibited similar morphologies with micrometer sized irregular block shapes. The BET surface area of PbO powders is increased up to 11 m2 g−1. For such PbO powders applied as anode materials in Lead acid batteries, we have managed to retain a reversible capacity above 60 mAh g−1 beyond cycles.
