Hi, does anyone know about lead-acid car battery?
The half reactions are:
PbO2 + 4H(+) + SO4(2-) + 2e -> PbSO4 +2H2O
Pb + SO4(2-) -> PbSO4 +2e
Why can PbO2 act as the cathode of a lead-acid car battery? Is PbO2 an solid ionic compound that do not conduct electricity?
Besides, does anyone know what is the meaning of "boosting a car battery"?
