Abstract—In this work, lead dioxide coatings deposited from nitrate electrolytes containing nickel ions as an additive are investigated. It is shown that lead dioxide electrodes micromodified with nickel are formed upon the deposition that differ from conventional PbO2 anodes in their physicochemical properties. It is established that modifying lead dioxide with nickel leads to a considerable growth in the number of labile oxygen-containing species at the electrode surface, which, in turn, results in an increased electrocatalytic activity of the coating.
