About Lithium

Lithium is the lightest metallic element, with atomic number 3, and is highly reactive due to its single valence electron. Lithium compounds play an important role in rechargeable batteries, ceramics, glass, lubricants, pharmaceuticals, and specialty inorganic materials. In advanced energy systems, lithium is used in cathode, electrolyte, and solid state battery materials, including sulfides, oxides, phosphates, and other lithium containing compounds.
