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.
Chemical energy is converted into electrical energy which is delivered to load. The lead-acid battery can be recharged when it is fully discharged. For recharging, positive terminal of DC source is connected to positive terminal of the battery (anode) and negative terminal of DC source is connected to the negative terminal (cathode) of the battery.
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.
As a lead-acid battery is charged in the reverse direction, the action described in the discharge is reversed. The lead sulphate (PbSO 4) is driven out and back into the electrolyte (H 2 SO 4). The return of acid to the electrolyte will reduce the sulphate in the plates and increase the specific gravity.
According to recent research, the failure mode of lead–acid batteries is PAM weakening and shedding, and the battery lifespan is primarily confined to the positive electrode. As a consequence, the lead–acid battery has hit a stumbling block that must be addressed to improve the PAM of the lead–acid battery's efficiency.
