Lead-acid batteries and their composition

Lead-acid batteries have been used for over a century, and they continue to be popular in various applications, from vehicles to backup power systems. One critical component of these batteries is the acid used, which typically comes in two types: sulfuric acid and lead dioxide. Sulfuric acid is used as the electrolyte in the cell, while lead dioxide is used as the positive plate.

When the battery is charged, lead dioxide undergoes a chemical process that causes it to release oxygen, which reacts with the sulfuric acid to produce lead sulfate and water. This reaction creates an excess of electrons on the negative plate, giving the battery its charge. When the battery is discharged, the opposite happens: lead sulfate on the negative plate reacts with sulfuric acid to produce lead and lead dioxide on the positive plate.

This reaction absorbs the excess electrons, causing the battery to discharge its charge.While sulfuric acid and lead dioxide are known to be dangerous substances, lead-acid batteries are still widely used due to their efficiency and low cost. However, proper care and handling are crucial as mishandling can lead to acid leaks, explosions, and serious injuries.

Despite the risks, lead-acid batteries remain a valuable resource for industries that require reliable and affordable power sources.
