Concept:A lead-acid accumulator uses lead compounds for its electrodes, with the negative pole made of pure lead.
Explanation:In a simple lead-acid accumulator, the negative plate is spongy lead metal, written as
Pb.
The positive plate is lead dioxide,
PbO2.
The electrolyte is dilute sulphuric acid,
H2SO4.
So the negative pole is not lead peroxide, zinc peroxide, or sulphuric acid.
It is simply a lead plate.
