Free QuoteIn a lead-acid battery, the cathode is made of lead-dioxide, and the anode is made of metallic lead. The two electrodes are separated by an electrolyte of sulfuric acid.

Free Quote(3) Accumulation of lead sulfate in the electrodes or sulfation. Lead sulfate is sparingly soluble in sulfuric acid, and deposits as particles onto active materials during discharge. These particles dissolve and lead ions are reconverted into active materials in the charging step.
Cell voltage decreases during discharge, and it will always be less than that of a fully charged battery. Thus, all Q coulombs withdrawn during discharge of any cycle will go into formation of lead sulfate. However, as charge put in approaches Q, the surface area of lead sulfate particles decreases to a small value.
Additive effects of aluminium sulfate in the sulfuric electrolyte solution of lead acid battery had no improvement on the charge cycle and stability of the cathode with reference to the battery made of dilute sulfuric acid electrolyte.
In this instructable a novel (resistive) pulsing approach is described for driving the lead-sulfate back into solution that is faster than the more traditional inductive method. Sulfation is not the only aging mode in lead acid batteries, so while desulfation may extend the life, it will not do so indefinitely.
The reaction reverses during charge, lead sulfate being decomposed to produce lead dioxide and lead. Both reactions take place via dissolution–precipitation processes. During discharge, electrons are transferred to form lead ions then dissolved into the solution and supersaturation of Pb 2+ may be achieved.
The reaction of lead and lead oxide with the sulfuric acid electrolyte produces a voltage. Supplying energy to an external load discharges the battery. During discharge, both plates convert to lead sulfate (PbSO 4) and the electrolytes becomes less acidic.
