chemistry of lead sorage battery recharging
It is most commonly used in automobiles and invertors.It consists of a lead anode and a grid of lead packed with PbO2 as cahode.A 38% sulfurc acid is used as an electrolyte.
The cell reaction is as folows:
ANODE
Pb +SO42- -------PbSO4 +2e-
PbO2 +SO4^2- +4H+ +2e- ----PbSO4 +2H2O
On recharging the cell reaction is reversed and PbSO4 on anode and cathode is converted into PbO2 and Pb
