Lithium carbonate, or Li2CO3, is a chemical compound composed of lithium, carbon, and oxygen. It appears as a white, odorless powder and is commonly used in various applications, including the production of lithium-ion batteries, ceramics, and glass. Additionally, it serves as a medication for treating bipolar disorder, helping to stabilize mood swings. In nature, lithium carbonate can be found in mineral deposits and brine sources. It is produced through processes such as evaporation of brine or mining of minerals like spodumene. The compound is essential in the growing field of renewable energy, particularly in electric vehicle technology.
