Batteries

Lead-acid batteries involve sulfuric acid solution with two submerged metal plates, a neutral lead anode and a lead (IV) oxide cathode (PbO 2). As the battery initiates, the acidic medium helps to oxidize the neutral lead into lead (II) sulfate (PbSO 4). Simultaneously, the lead oxide at the cathode also converts into PbSO 4, but through reduction.
