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.
The mechanism of the positive plate charge in pulse regime was studied in model lead-acid cells with one positive and two negative plates (8 Ah each) and Ag/Ag 2 SO reference electrodes. The results showed that the evolution of the electrode potential is much slower on the positive plate than on the negative plate.
During the period of the pulse charge on the positive plate the reaction of oxygen evolution also takes place. This process proceeds on the same active centers located in the gel part of the lead dioxide as Reaction (4c), according to the following mechanism (5a)Pb*O (OH)2 → Pb*O (OH)+(OH) + e− (5b)Pb*O (OH)+(OH) + H2O → Pb*O (OH)2
The charging velocity indicates the charge time. The charging time determines battery health. From this point of view, the negative method of discharge of pulses is stated (Yifeng and Chengning 2011). The current of battery charging directly affects the impact of charging. The charging is to be increased by increasing the charge current rate.
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.
The chemical reactions are again involved during the discharge of a lead–acid battery. When the loads are bound across the electrodes, the sulfuric acid splits again into two parts, such as positive 2H + ions and negative SO 4 ions. With the PbO 2 anode, the hydrogen ions react and form PbO and H 2 O water.
