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.
The construction of lead acid batteries involves several key components. Each battery contains two lead plates, one made of lead dioxide and the other of sponge lead, submerged in sulfuric acid electrolyte. These plates are positioned in a durable container, often made of plastic or glass, ensuring safety and functionality.
The functioning of a lead-acid battery involves electrochemical reactions at the anode and cathode. During discharge, the anode sees the conversion of lead (Pb) to lead sulfate (PbSO4) while the cathode involves the transformation of lead dioxide (PbO2) to lead sulfate (PbSO4), releasing energy in the process.
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. The U.S. Department of Energy defines lead-acid batteries as “highly efficient” in their energy storage and delivery.
The electrolyte in a lead acid battery isn’t just any liquid; it’s a mix of sulfuric acid and water. This isn’t just to fill space; it’s a vital player. It carries charged particles between the plates, making the whole energy storage process possible. During charging, the electrolyte undergoes a change too.
Utilizing lead alloy ingots and lead oxide, the lead battery is made of two chemically dissimilar lead-based plates immersed in a solution of sulphuric acid. How do you maintain a lead-acid battery? Apply a fully saturated charge of 14 to 16 hours to keep lead acid in good condition.
