The most important use of lithium is in rechargeable batteries for electric vehicles, energy grid storage, mobile phones, laptops, digital cameras and other small electronic devices. Lithium is also used in some non-rechargeable batteries.
Lithium metal is combined with aluminum and magnesium to form strong and lightweight alloys for armour plating, aircraft, trains and bicycles.
Optics, Glassware and Ceramics
Lithium is used to produce optics, glassware, and ceramics.
Lithium chloride is one of the most hygroscopic materials known, and is used in air conditioning and industrial drying systems.
Lithium stearate is used as an all-purpose and high-temperature lubricant.
Lithium carbonate is used in medications to effectively treat manic depression.
Lithium hydroxide and lithium carbonate are both consumed in battery cathodes. The high energy content and light molecular weight of lithium makes it an ideal energy source for transportation.
