electrochemical processes. For instance, the grids are usually made of lead-antimony alloys containing 3 to 11 wt % antimony to improve the mechanical properties of the grids (Crompton, 2000). However, antimony decreases over-potential of hydrogen evolution at the negative plate (Hirasawa et al, 2000, Rogatchev et al, 1976).The absence of

Lead dioxide (PbO 2) has drawn much attention due to its good electrical conductivity, low cost and high resistance to corrosion.3 However, there are still some drawbacks such as high over-potential for oxygen evolution, low stability, and low electro-

zinc electrowinning process. Pb-Ag alloys are currently used as anodes in the zinc electrowinning industry. Because the lead surface is easily oxidized to high prices during use, and the oxide becomes PbO 2 to prevent the oxidation of the lead anodes. PbO 2 has good electrical conductivity. However, its mechanical properties are poor,
