typically reduced to lead(II) ion, Pb2+; lead(IV) ion, Pb4+, is not found in aqueous solution. The most important use of lead dioxide is as the cathode of lead acid batteries. This arises from the anomalous metallic conductivity of PbO2—TiO2, ZrO2, GeO2, and SnO2 are all insulators with a band gap around 3eV, however PbO2 is a metallic conductor. . This

Choosing the right battery Lead-acid models can be more affordable, but also can suffer from sudden failure. Nickel-cadmium (NiCd) units are more expensive, but generally decline slowly—rather than all at once—so owners have greater warning when replacement is needed and can worry less that any single event will trigger failure.
