lead dioxide, a negative electrode of 'spongy lead' and an electrolyte of aqueous sulphuric acid. The active material is supported on a grid framework of metallic lead alloy (Pb-Sb, Pb-Ca or Pb-Ca-Sn). In addition to supporting the active material, the grid serves as a current conductor, the function of which is to maintain a uniform. On recharge, the lead sulfate on both electrodes converts back to lead dioxide (positive) and sponge lead (negative), and the sulfate ions (SO 4 2) are driven back into the electrolyte solution to form sulfuric acid. The reactions involved in the cell follow.

The recent literature dealing with the redox mechanism of the lead-acid cell positive electrode is reviewed. The basis electrochemistry of lead dioxide in its various polymorphic modifications and states of subdivision is considered in relation to the important aspects of electrode technology of which the major industrial application of the material is the conventional lead-acid cell.

Kelly. Lead dioxide is the active constituent of the positive electrode in the lead‐acid battery. Both the α‐ and the β‐modifications are present in battery electrodes and X‐ray diffraction techniques must be used to differentiate the role of each in the reactions occurring in the lead‐acid battery rd samples of the two forms of lead dioxide are necessary for this purpose Cited by: Lead-Acid Batteries: Science and Technology: A Handbook of Lead-Acid Battery Technology and Its Influence on the Product, Second Edition presents a comprehensive overview of the technological processes of lead-acid battery manufacture and their influence on performance parameters.
The book summarizes current knowledge on lead-acid battery production, presenting it in the form of an integral. Studies to investigate various baths for the deposition of lead and lead dioxide have been carried out.

Also, the effect of a sweep rate, the range of potential polarisation and temperature has been by: The effects of ultrasound on electrochemical processes suggest significant benefits. These include modifications to the chemistry of reactions at the electrode and greatly increased current efficiencies.
One major result of these studies could be that, in the future, industrial electrochemistry might become a more attractive proposition.
which modifications of lead oxides have been studied. There are many data about the electrochemistry of both modifications of lead dioxide in strongly alkaline and sulfuric acid solutions29,30 and of a-PbO 2 in neutral media. 31 No data on the electrochemical behaviour of BaPbO 3 are available.
