Which non metal compound is used in car batteries

Car batteries are an essential component of any automobile, providing the necessary electrical energy to start the engine and power various electrical systems. While the lead-acid battery has been the most commonly used type for many years, there are a number of other battery technologies available today, including Lithium-Ion, Nickel-Cadmium, and Nickel-Metal Hydride.

One of the non-metallic compounds commonly used in car batteries is sulfuric acid. This compound is used as the electrolyte in lead-acid batteries, which is a crucial component of the chemical reactions that produce electrical energy.

Sulfuric acid works by breaking down the lead oxide paste on the battery plates, creating lead sulfate and water. This releases electrons, which create an electrical current that powers the vehicle. Sulfuric acid is also used to recharge the battery when the engine is running, by releasing hydrogen gas and converting lead sulfate back into lead oxide paste.
