Lithium hydroxide, with the chemical formula LiOH, is an inorganic compound that exists in two common forms: anhydrous lithium hydroxide (LiOH) and lithium hydroxide monohydrate (LiOH·H₂O). It appears as a white crystalline solid, is highly hygroscopic, and readily dissolves in water to form an alkaline solution.

Main Industrial Uses

Battery Industry

It is a core raw material for manufacturing lithium-ion batteries, especially high-performance cathode materials such as lithium cobalt oxide (LiCoO₂), lithium nickel cobalt manganese oxide (NCM), and lithium nickel cobalt aluminum oxide (NCA). With the rapid development of new energy vehicles and energy storage systems, the demand for lithium hydroxide in this field is growing significantly.

Aerospace Field

Due to its high efficiency in absorbing carbon dioxide, it is used in the life support systems of spacecraft and submarines to remove (CO₂) from the breathing air of crew members.

Other Applications

Used as a catalyst in organic synthesis reactions.

Applied in the production of lubricating oils, greases, and special glass.

Serves as a raw material for manufacturing other lithium compounds (e.g., lithium fluoride, lithium bromide).
