Lithium hydroxide is used in the manufacture of lithium salts (soaps) of stearic and other fatty acids.
These soaps are widely used as grease lubricant thickeners to improve heat resistance, water resistance, stability and mechanical properties. Grease additives can be used in car, plane and crane bearings etc.
The calcined solid lithium hydroxide can be used as carbon dioxide absorbent for crew members on the spacecraft and the submarine.
Spacecraft from NASA's Mercury, Geminni and Apollo projects used lithium hydroxide as absorbents. It has reliable performance and can easily absorb carbon dioxide from water vapor. The chemical reaction is: 2LiOH + CO 2 Li 2 CO 3 + H 2 OR.

1g of anhydrous lithium hydroxide can absorb carbon dioxide with a volume of 450ml. Only 750 g of anhydrous lithium hydroxide can soak carbon dioxide exhaled by one person each day.
Lithium hydroxide and other lithium compounds have recently been used for the development and study of alkaline batteries (ENCYCLOPÆDIA BRITANNICA, 2013).
