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―

Anode
Positive and negative electrode vs. anode and cathode for a secondary battery. Battery manufacturers may regard the negative electrode as the anode, [9] particularly in their technical literature. Though from an electrochemical viewpoint incorrect, it does resolve the problem of which electrode is the anode in a secondary (or rechargeable) cell.
