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).
What is a lead acid battery?
Lead Acid Battery – The type of battery which uses lead peroxide and sponge lead for the conversion of the chemical energy into electrical energy, such type of the electric battery is called a lead acid battery. Because it has higher cell voltage and lower cost, the lead acid battery is most often used in power stations and substations.
How is a lead acid storage battery formed?
The lead acid storage battery is formed by dipping lead peroxide plate and sponge lead plate in dilute sulfuric acid. A load is connected externally between these plates. In diluted sulfuric acid the molecules of the acid split into positive hydrogen ions (H +) and negative sulfate ions (SO 4 − −).
What is the initial formation charge of a lead-acid battery?
The initial formation charge of a lead-acid battery, whether in the form of plates or as an already assembled battery, is quite a complex bundle of chemical reactions. It is important to know in principle about the most important parameters controlling this process in order to achieve good reproducible results with reasonable efforts.
What happens if a lead acid cell is charged in the opposite direction?
Now to charge the Lead acid cell current in the opposite direction is applied, this way the chemical reaction is reversed and once again the +ve plate becomes Lead peroxide and the negative plate become pure lead, during the same process the electrolyte is also restored i.e electrolyte becomes sulfuric acid.
