Study on Anode Material PbO_2 of Secondary Lead Battery with X-ray Diffraction Method
Li Gang ( Chem. & Phys. Central lab., Nanjing Normal University)
Studies have been made on anode material PbO2 of the secondary lead battery with X-ray diffraction method. The results indicate that there are two kinds of lead oxide on the anode. One of them is α-PbO2, and the other is β-PbO2. The former is of orthorhombic system distributing on the surface of the anode and the latter is of tetragonal system lying inside the anode.If the anode material were crushed to powder, content of α-PbO2 and β-PbO2 would be almost equal.
