Lithium is a soft, silvery-white alkali metal with the atomic number 3 and symbol Li on the periodic table. It is the lightest solid element and the least dense metal, making it highly reactive with water and air. Discovered in 1817 by Johan August Arfwedson, lithium is primarily extracted from brine pools and hard rock mines, with major reserves in countries like Chile, Australia, and Argentina.
Chemically, lithium forms compounds used in various industries. It has a low electrochemical potential, which makes it ideal for rechargeable batteries, powering everything from smartphones and laptops to electric vehicles. Lithium-ion batteries dominate the market due to their high energy density, long cycle life, and lightweight properties.
Beyond batteries, lithium is used in ceramics, glass production, and as a flux in welding. In medicine, lithium carbonate treats bipolar disorder by stabilizing mood. It also appears in alloys for aircraft parts and in nuclear reactors for tritium production.
The global demand for lithium has surged with the rise of renewable energy and electric mobility, positioning it as a critical resource in the transition to sustainable technologies. However, mining and processing raise environmental concerns, including water usage and potential ecosystem disruption. Efforts are underway to develop more sustainable extraction methods and recycling programs to meet future needs.
