Plates in a lead-acid battery are the essential components that facilitate the electrochemical reactions necessary for energy storage and release. Each battery consists of positive and negative plates, typically made of lead and lead dioxide, immersed in an electrolyte solution.
It consists of lead dioxide (PbO2) as the positive plate, sponge lead (Pb) as the negative plate, and an electrolyte solution of sulfuric acid (H2SO4). The United States Department of Energy defines a lead-acid battery as “a type of rechargeable battery that uses lead and lead oxide as its electrodes and sulfuric acid as an electrolyte.”
A lead-acid battery cell has two plates: a positive plate and a negative plate. The positive plate is coated with lead dioxide paste, while the negative plate is made of sponge lead. These plates are separated by a material known as a separator. This design allows the lead-acid battery to operate efficiently.
The container is a fundamental part of the lead acid battery’s construction. There are, in general, two methods of producing the active materials of the cell and attaching them to lead plates. These are known after the names of their inventors. Plante plates or formed lead acid battery plates. Faure plates or pasted lead acid battery plates.
The active ingredients in the lead–acid battery (LAB) are lead dioxide at the positive plate and sponge lead at the negative plate; these are the solid-phase materials that are responsible for producing energy. At any state-of-charge (SoC), both the battery plates will also contain some lead sulfate solids.
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).
