Sulfuric acid is a strong, highly corrosive acid with the chemical formula H2SO4. It is a dense, colorless liquid that is soluble in water and has a high boiling point. Sulfuric acid is a hygroscopic substance, meaning it readily absorbs moisture from the air, and is highly reactive with many substances, including metals, organic materials, and other acids.
These efforts must take into account the complex interplay of electrochemical and chemical processes that occur at multiple length scales with particles from 10 nm to 10 µm (see the second figure) ().The …

Electrical energy is used to drive the chemical reactions where electrical energy is converted to chemical energy stored in the battery. (e) Electrolyte (sulfuric acid): The sulfuric acid (H 2 SO 4) in the electrolyte serves multiple purposes. It provides the medium for ions to flow between the two plates during discharging and charging.
In lead-acid battery manufacturing, sulfuric acid (H 2 SO 4) is used to activate the lead elements of the lead battery to get the power effect. For this process, the acid with correct concentration level is required. The acid is prepared by mixing the fresh acid with water and pumping it into the lead activation plant.
