In lead acid batteries, PbO is the starting precursor paste material for both anode and cathode, which is then converted to active Pb and PbO 2, respectively, during cell formation stage. There is big interest to improve lead oxide characteristics to obtain more discharge capacity and more cycle-life.
The CV's of nanostructured lead oxide have shown the whole spectrum of possible reactions occurring in lead acid battery. Moreover, the nanostructured lead oxide shows good reversible ability and cycle stability (over 15 cycles), which shows potential applications in lead acid battery. 4. Conclusions
Because of the simplicity of design, low cost of manufacture, reliability and relative safety when compared to other electrochemical systems of lead-acid batteries, there is a high interest to improve and develop lead oxide characteristics to obtain more discharge capacity and more cycle-life.
Lead oxide has many crystalline forms, such as PbO (α, β), Pb 2 O 3, Pb 3 O 4, and PbO 2 (α, β). Lead dioxide (PbO 2 ), which is used as a positive active material in lead acid battery, has been extensively studied.
Lead dioxide (PbO 2 ), which is used as a positive active material in lead acid battery, has been extensively studied. Several electrochemical methods, such as cyclic voltammetry (CV) , constant current and constant voltage approaches, have been developed recently to prepare nano-structured PbO 2.
