Lead–acid batteries constitute approximately 40% of the world's total battery sales, which can be attributed to their well-developed and robust technology and significant cost advantage. Lead–acid batteries consist of a metallic lead (Pb) negative electrode, a lead dioxide (PbO 2) positive electrode, and a sulfuric acid electrolyte.
Sulphation in Lead Acid Battery refers to the formation of Lead Sulphate (PbSO4) on the plates of battery. For better understanding of Sulphation, let us first consider the chemical reaction taking place in the lead acid battery. In lead acid battery, lead dioxide (PbO2) acts as a positive plate and lead (Pb) acts as a negative plate.
When a lead-acid battery is discharged, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead. In the charged state, the main components of the positive and negative electrodes are lead sulfate [43, 44].

As the battery undergoes discharge, the lead and the lead dioxide electrodes react with sulfur in the electrolyte to form lead sulfate (PbSO 4). During the charging process, the lead sulfate will be broken down into lead and lead dioxide and the sulfur ions will recombine with water in the electrolyte to form the electrolyte.
A lead-acid battery used sulfuric acid that is diluted with distilled water in the ratio of 35% to 65% respectfully as the electrolyte. This is the solution through which the electrochemical reactions take place.
