Lithium metals uses

Lithium metal's primary uses include rechargeable batteries for consumer electronics and electric vehicles, high-performance alloys with aluminum and magnesium for aerospace and automotive applications, and specialty lubricants like high-temperature greases. It is also used in specialty glass and ceramics, as a deoxidizer in metallurgy, and in medical treatments for bipolar disorder.

Electronics and energy

• Batteries:As a key component in lithium-ion batteries, it powers a vast range of devices, from smartphones and laptops to electric vehicles and grid-scale energy storage systems.
• Primary batteries:The light weight and high energy density of lithium metal make it suitable for non-rechargeable primary batteries.

Industrial applications

• Alloys:It is used to create lightweight and strong alloys with aluminum and magnesium, which are used in aircraft, bicycle frames, and high-speed trains.
• Glass and ceramics:Lithium compounds are added to glass and glass-ceramics to lower melting points and improve thermal resistance and durability, used in products like stovetops and specialty glass.
• Lubricants:Lithium soaps are used to make high-temperature and all-purpose lubricating greases that perform well in a wide range of temperatures.
• Metallurgy:It is used as a deoxidizer or degasser in the production of alloys like iron, steel, and zinc, helping to remove impurities and prevent defects.

Medical and other uses

• Medicine:Lithium salts are used to treat bipolar disorder and manic depression, acting as a mood stabilizer.
• Chemicals:It is used as an initiator for polymerization reactions to produce synthetic rubber and is a precursor for compounds like lithium hydride.

The uses of lithium metal span various industries, with the largest and most important application being in batteries for electronics and electric vehicles. Its unique properties, such as being the lightest solid metal and having a high electrochemical potential, make it essential for modern technology.
