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.

electrochemistry to students in varied fields, including analytical, physical and materials chemistry. The major course content will include Part I Fundamentals Overview of electrode processes (Ch. 1) Potentials and thermodynamics (Ch. 2) Electron transfer kinetics File Size: 2MB. (i) The cell reactions during the use (discharge) of lead storage battery are: The cell reactions when the battery is in use are given below:Anode: Pb(s) + SO(aq) → PbSO4 + 2e-Cathode:PbO2(s) + 4H+(aq) + SO(aq) → PbSO4(s) + 2H2O(l)i.e., overall cell reaction consisting of cathode and anode reactions is:Pb(s) +PbO2 +4H+(aq) +SO(aq) → 2PbSO4(s) + 2H2O(l)ii) Recharging a lead-acid.
