The influence of the ultrasonic field on lead dioxide electrodeposition from nitrate electrolyte was studied. The adsorption of electroactive particles and the amount of nucleation on the electrode surface were found to have increased as well as the formation of OH-radicals accelerated under the influence of the ultrasonic field. Fine-crystalline deposits of lead dioxide were formed, which contributed to obtaining high current yield of lead dioxide, coefficient increasing of the electrode active mass and increasing of the discharge capacity of the emergency current generator cell layout. It was shown that the application of ultrasound in producing a lead dioxide electrode made it possible to reduce the time of the technological procedure.
