Lithium: Uses, Properties & Key Facts

Overview

From smartphones in your pocket to electric vehicles on the road, one lightweight metal powers much of the modern world. Lithium has become one of the most strategically important elements of the twenty-first century because of its essential role in rechargeable batteries and the global transition toward cleaner energy.

Lithium is a soft, silvery-white chemical element with the symbol Li and atomic number 3. It is the lightest metal and the lightest solid element on the periodic table. Although highly reactive and never found in pure form in nature, lithium occurs in mineral deposits and salt-rich brines around the world.

Today, lithium is indispensable in rechargeable batteries used in smartphones, laptops, electric vehicles, renewable energy storage systems, and countless portable electronic devices. It is also used in ceramics, glass, lubricants, pharmaceuticals, and specialized industrial applications.
