Lead contributes to the function of a lead acid battery by serving as a key component in the battery’s electrodes. The battery contains two types of electrodes: the positive electrode, which is made of lead dioxide (PbO2), and the negative electrode, which consists of sponge lead (Pb).
The chemical reaction on the positive plate involves the oxidation of lead during discharge and its reduction during charging. Negative Lead Plates: Negative lead plates are made from sponge lead (Pb). These plates store negative charge, and during discharge, lead reacts with the sulfate in the electrolyte.
Battery Acid: The acid is a high-purity solution of sulfuric acid and water. Battery Negative Plate: The negative plate contains a metal grid with spongy lead (Pb 2+) active material. Battery Positive Plate: The positive plate contains a metal grid with lead dioxide (PbO 2) active material.
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).
The effectiveness of a lead-acid battery is largely influenced by its components. Now, let’s explore each component in detail: Positive Lead Plates: Positive lead plates are made from lead dioxide (PbO2). These plates store positive charge during the battery’s discharge cycle.
In summary, lead acid batteries are composed of lead dioxide, sponge lead, sulfuric acid, water, separators, and a casing. Each material contributes to the overall performance and safety of the battery system. How Does Lead Contribute to the Function of a Lead Acid Battery?
