What are the two types of electrodes in a lithium ion battery?
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). During charging, lead at the negative electrode reacts with sulfate ions to form lead sulfate (PbSO4) while lead dioxide on the positive electrode interacts with hydrogen ions.
What is the electrolyte in a lead-acid battery?
As mentioned earlier, the electrolyte in a lead-acid battery is a dilute solution of sulfuric acid (H 2 SO 4 ). The negative electrode of a fully charged battery is composed of sponge lead (Pb) and the positive electrode is composed of lead dioxide (PbO 2 ). Release of two conducting electrons gives lead electrode a net negative charge
How do lead-acid batteries work?
Battery Application & Technology All lead-acid batteries operate on the same fundamental reactions. As the battery discharges, the active materials in the electrodes (lead dioxide in the positive electrode and sponge lead in the negative electrode) react with sulfuric acid in the electrolyte to form lead sulfate and water.
How does lead contribute to the function of a lead acid battery?
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).
What materials are in a lead-acid battery?
These materials include the electrolyte and the positive and negative electrodes. As mentioned earlier, the electrolyte in a lead-acid battery is a dilute solution of sulfuric acid (H 2 SO 4 ). The negative electrode of a fully charged battery is composed of sponge lead (Pb) and the positive electrode is composed of lead dioxide (PbO 2 ).
What is the chemistry of a lead-acid battery?
The chemistry of lead-acid batteries involves oxidation and reduction reactions. During discharge, lead dioxide and sponge lead react with sulfuric acid to produce lead sulfate (PbSO4) and water. When recharged, the process is reversed, regenerating lead dioxide, sponge lead, and sulfuric acid.
