Battery acid is a common name for sulfuric acid (US) or sulphuric acid (UK). Sulfuric acid is a mineral acid with the chemical formula H 2 SO 4. In lead-acid batteries, the concentration of sulfuric acid in water ranges from 29% to 32% or between 4.2 mol/L and 5.0 mol/L. Battery acid is highly corrosive and able to cause severe burns.
The production of SO 2, its conversion to SO 3, and the dilution of H 2 SO 4 are exothermic processes that are exploited to reduce energy costs at sulfuric acid plants. Sulfur emissions have been sharply reduced by using two SO 3 absorbers, although one absorber is the economic choice. Tail gas scrubbing processes have been developed to …

During charging, the lead-acid battery undergoes a reverse chemical reaction that converts the lead sulfate on the electrodes back into lead and lead dioxide, and the sulfuric acid is replenished. This process is known as "recharging" and it restores the battery''s capacity to store electrical energy.
The reaction principle of lead-acid battery remains unchanged for over 150 years from the invention. As shown in reaction formula for the discharging of battery, at the negative electrode, metallic lead reacts with the sulfate ions in water solution to produce lead sulfate and release electrons (Formula 1).At the positive electrode, lead dioxide reacts …
