Chemical changes during:
Discharging:
The current will flow from positive to negative plate in the external circuit. As current now enters by negative plate, the negative plate becomes anode and the positive plate cathode. As, hydrogen ions will move to PbO2 plate and sulphate ions towards Pb plate. Therefore, following actions take place:
