Negative Electrodes of Lead-Acid Batteries | 7 | Lead-Acid Battery

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. The performance of a lead-acid
