For example, lead-acid batteries typically use lead dioxide (PbO2) as the positive electrode and spongy lead (Pb) as the negative electrode. These electrodes are submerged in an electrolyte solution made up of water and sulfuric acid (H2SO4).
Lead-acid batteries are prone to a phenomenon called sulfation, which occurs when the lead plates in the battery react with the sulfuric acid electrolyte to form lead sulfate (PbSO4). Over time, these lead sulfate crystals can build up on the plates, reducing the battery''s capacity and eventually rendering it unusable.
