Lithium is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal.

Under standard conditions, it is the lightest metal and the lightest solid element. Like all alkali metals, lithium is highly reactive and flammable, and it must be stored in mineral oil. When cut, it exhibits a metallic luster, but moist air corrodes it quickly to a dull silvery gray, then black tarnish. It never occurs freely in nature, but only in (usually ionic) compounds, such as pegmatitic minerals that were once the main source of lithium.

Lithium and its compounds have several industrial applications, including:

Batteries

Lithium-ion batteries are widely used in various electronic devices such as laptops, smartphones, cameras, and electric vehicles due to their high energy density and long life.

Medicine

Lithium compounds are used as mood-stabilizing drugs, primarily in the treatment of bipolar disorder.

Industrial Processes

Lithium compounds are used in various industrial processes, such as the production of glass, ceramics, and aluminum.

Greases and Lubricants

Lithium-based greases are commonly used in lubricating applications.

It’s important to note that while lithium has valuable applications, the extraction and processing of lithium can have environmental impacts, and there is ongoing research into more sustainable and environmentally friendly methods of obtaining lithium.

Additionally, the demand for lithium has increased significantly with the growing use of lithium-ion batteries in electric vehicles and renewable energy storage systems.
