The lead acid battery uses lead as the anode and lead dioxide as the cathode, with an acid electrolyte. The following half-cell reactions take place inside the cell during discharge: At the anode: Pb + HSO4– → PbSO4 + H+ + 2e– At the cathode: PbO2 + 3H+ + HSO4– + 2e– → PbSO4 + 2H2O Overall: Pb + PbO2 +2H2SO4 → 2PbSO4 + 2H2O
At its core, a lead-acid battery is an electrochemical device that converts chemical energy into electrical energy. The battery consists of two lead plates, one coated with lead dioxide and the other with pure lead, immersed in an electrolyte solution of sulfuric acid and water.
In the charged state, the positive active-material of the lead–acid battery is highly porous lead dioxide (PbO 2). During discharge, this material is partly reduced to lead sulfate. In the early days of lead–acid battery manufacture, an electrochemical process was used to form the positive active-material from cast plates of pure lead.
Depending on the pH, i.e. the presence of sulfuric acid or sulfate, lead oxide or one of lead sulfates de-scribed above are the most favorable compounds. Both lead dioxide and metallic lead, the final active materi-als in the lead-acid battery, are on a higher energy level.
A lead-acid battery stores energy through a chemical reaction that takes place between lead and lead dioxide plates and sulfuric acid electrolyte. The energy is stored in the form of potential difference or voltage between the two electrodes.
When a lead-acid battery is in use, it undergoes a discharge process. During this process, the lead-acid battery releases electrical energy as its chemical energy is converted. The discharge process can be described as follows: The sulfuric acid in the electrolyte combines with the lead dioxide on the positive plate to form lead sulfate and water.
