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.
A Lead Acid Battery consists of the following things, we can see it in the below image: A Lead Acid Battery consists of Plates, Separator, and Electrolyte, Hard Plastic with a hard rubber case. In the batteries, the plates are of two types, positive and negative. The positive one consists of Lead dioxide and negative one consists of Sponge Lead.
In a lead-acid battery, two types of lead are acted upon electro-chemically by an electrolytic solution of diluted sulfuric acid (H 2 SO 4). The positive plate consists of lead peroxide (PbO 2), and the negative plate is sponge lead (Pb), shown in Figure 4. Figure 4 : Chemical Action During Discharge
If we break the name Lead Acid battery we will get Lead, Acid, and Battery. Lead is a chemical element (symbol is Pb and the atomic number is 82). It is a soft and malleable element. We know what Acid is; it can donate a proton or accept an electron pair when it is reacting.
The lead acid battery is most commonly used in the power stations and substations because it has higher cell voltage and lower cost. The various parts of the lead acid battery are shown below. The container and the plates are the main part of the lead acid 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.
