- At the positive plate: Lead dioxide (PbO2) reacts with the sulfuric acid and the released hydrogen ions to form lead sulfate (PbSO4) and water (H2O).
The lead sulfate formed on both plates is what stores the electrical energy.
Discharging Process
When a car battery is discharging, the reverse reactions occur:
- At the positive plate: Lead sulfate (PbSO4) reacts with water (H2O) to form lead dioxide (PbO2), sulfuric acid (H2SO4), and release electrons.
