Litio, or lithium in English, is a soft, silvery-white metal that belongs to the alkali metal group on the periodic table. It is the lightest metal and has a low density, making it highly reactive and flammable. Lithium is primarily used in rechargeable batteries for electronic devices, electric vehicles, and energy storage systems due to its ability to store and release energy efficiently. In addition to its role in batteries, lithium is also used in various industrial applications, including the production of glass, ceramics, and lubricating greases. Furthermore, lithium compounds are utilized in the medical field to treat bipolar disorder, helping to stabilize mood swings in patients.
