Lead-acid Battery Handbook
Reaction at the negative electrode. When a lead-acid battery is discharged after connecting a load such as a light bulb between its positive and negative electrodes, the lead (Pb) in the negative electrode releases electrons (e －) to form lead ions (Pb2+). Pb → Pb2+ ＋ 2e － Then the lead ions immediately bond with sulfate ions (SO. 4 2―

The negative electrode is one of the key components in a lead-acid battery. The electrochemical two-electron transfer reactions at the negative electrode are the lead oxidation from Pb to PbSO4 when charging the battery, and the lead sulfate reduction from PbSO4 to Pb when discharging the battery, respectively.
Lead-Acid Battery Basics
A lead-acid battery cell consists of a positive electrode made of lead dioxide (PbO 2) and a negative electrode made of porous metallic lead (Pb), both of which are immersed in a sulfuric acid (H 2 SO 4) water solution. This solution forms an electrolyte with free (H+ and SO42-) ions. Chemical reactions take place at the electrodes:
