Preparation Technology of Lead Dioxide Electrode

Lead dioxide coating was prepared on a Ti substrate by pulsed current technique. The effect of the pulsed current density, pulsed time and relaxation time on the morphology and electrochemical properties of the coating was studied by means of scanning electron microscopy and electrochemical testing. Compared with lead dioxide fabricated by common electroplate technique, lead dioxide prepared by pulsed current technique is more dense, has no hole, shows better corrosion resisting property and more stable electrochemical properties.
