There are huge chemical process is involved in Lead Acid battery’s charging and discharging condition. The diluted sulfuric acid H 2 SO 4 molecules break into two parts when the acid dissolves. It will create positive ions 2H+ and negative ions SO 4 -. As we told before, two electrodes are connected as plates, Anode and Cathode.
In the charging process we have to pass a charging current through the cell in the opposite direction to that of the discharging current. The electrical energy is stored in the form of chemical form, when the charging current is passed. lead acid battery cells are capable of producing a large amount of energy.
Construction, Working, Connection Diagram, Charging & Chemical Reaction Figure 1: Lead Acid Battery. The battery cells in which the chemical action taking place is reversible are known as the lead acid battery cells. So it is possible to recharge a lead acid battery cell if it is in the discharged state.
Charging of the lead batteries is usually done by providing an external current source. A plug is inserted which is linked to the lead-acid battery and the chemical reaction proceeds in the opposite direction.
The construction of a lead acid battery cell is as shown in Fig. 1. It consists of the following parts : Anode or positive terminal (or plate). Cathode or negative terminal (or plate). Electrolyte. Separators. Anode or positive terminal (or plate): The positive plates are also called as anode. The material used for it is lead peroxide (PbO 2).
Charging of lead–acid cell Discharging of a lead–acid cell The chemical reaction takes place at the electrodes during charging. On charge, the reactions are reversible. When cells reach the necessary charge and the electrodes are reconverted back to PbO 2 and Pb, the electrolyte's specific gravity rises as the sulfur concentration is enhanced.
