ABSTRACT:
A method for making porous lead dioxide electrodes having a relatively large active surface area and long service life is disclosed. The electrodes employ a grid which is coated first with a thin layer of nickel and then with a thin layer of lead. A paste containing a halogenated lead compound is applied over the lead and successively reduced and oxidized to form an active mass of porous lead dioxide. The finished porous lead dioxide electrode is suitable for use in storage batteries.
