A lead-acid battery has six cells that each contain a pair of lead electrodes in an electrolyte solution of about 35% sulfuric acid and 65% water. This gives the battery a nominal voltage of 12.6 volts. How Much Acid Should Be in a Battery? Batteries come in all shapes and sizes, and so do their corresponding acids.
A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.
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.
The electrolyte solution in a lead-acid battery consists of approximately 35% sulfuric acid and 65% water. The acid concentration is usually between 4.2-5 mol/L, and the solution has a density of 1.25-1.28 kg/L. The electrolyte solution plays a vital role in the battery’s operation.
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).
Following are some of the important applications of lead – acid batteries : As standby units in the distribution network. In the Uninterrupted Power Supplies (UPS). In the telephone system. In the railway signaling. In the battery operated vehicles. In the automobiles for starting and lighting.
