The anode and cathode reactions for the charging of a lead storage battery are as follows:
Anode reaction:
Pb(s) + HSO4-(aq) → PbSO4(s) + H+(aq) + 2e-
Cathode reaction:
PbO2(s) + HSO4-(aq) + 3H+(aq) + 2e- → PbSO4(s) + 2H2O(l)
Overall reaction:
Pb(s) + PbO2(s) + 2HSO4-(aq) + 2H+(aq) → 2PbSO4(s) + 2H2O(l)
During the charging process, lead sulfate (PbSO4) is formed on both the anode and cathode. This reaction allows the lead storage battery to store electrical energy for later use.
