Lead–Acid Batteries
The discharge state is more stable for lead–acid batteries because lead, on the negative electrode, and lead dioxide on the positive are unstable in sulfuric acid. Therefore, the chemical (not electrochemical) decomposition of lead and lead dioxide in sulfuric acid will proceed even without a load between the electrodes.
Lead Acid vs. Lithium-ion Batteries: A Comprehensive Comparison
They consist of lead dioxide (PbO2) as the positive electrode (cathode) and sponge lead (Pb) as the negative electrode (anode), with a sulfuric acid (H2SO4) electrolyte. When the battery discharges, the chemical reaction between the electrodes and the electrolyte produces lead sulfate (PbSO4) and water (H2O).
