AI Customer ServiceThe 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).
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.
A battery is an energy storage device. Here the lead–acid battery's working theory is discussed. It's rare in the world of rechargeable or secondary batteries. The positive plate contains lead dioxide (PbO 2), the negative plate contains sponge lead (Pb), and the electrolyte is dilute sulfuric acid (H 2 SO 4).
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.
Lead–acid batteries have issues with accelerated corrosion of the battery plates, faster self-discharge, rapid water loss, gas formation, and significant internal resistance variance.
The basic overall charge/discharge reaction in lead–acid batteries is represented by: Besides the chemical conversion of lead dioxide and metallic lead to lead-sulfate, also sulfuric acid as the electrolyte is involved in the cell internal reaction.
