What is a Lithium Hydroxide?
Lithium hydroxide is an inorganic compound with the formula LiOH. It can exist as anhydrous or hydrated, and both forms are white hygroscopic solids. They are soluble in water and slightly soluble in ethanol. Both are available commercially.

How do you get lithium hydroxide?
Lithium hydroxide is made by reacting lithium carbonate with calcium hydroxide. A calcium carbonate solid is made and a lithium hydroxide solution is left behind. It can also be made by reacting lithium with water or by reacting lithium oxide with water.
Who uses lithium hydroxide?
Lithium Hydroxide Monohydrate is used in the production of cathode material for lithium-ion electric vehicle batteries and is more suitable as it provides the best energy balance.
Can lithium hydroxide be used in batteries?
Lithium hydroxide is primarily used to make lithium-ion battery cathode materials like lithium cobalt oxide (LiCoO2) and lithium iron phosphate. As a precursor for lithium nickel manganese cobalt oxides, it is preferable over lithium carbonate.
What are the industrial uses of lithium hydroxide?
Lithium hydroxide is used as a grease additive (thickener, antioxidant, extreme pressure agent), which can improve heat resistance, water resistance, stability and mechanical properties; and lithium-based grease is often used for bearings in automobiles, trains, airplanes, cranes and any precious machines.
Why is lithium hydroxide better for batteries?
This is because lithium hydroxide is easily synthesized with nickel which increases the battery’s energy density when formulating cathode materials.
How do you convert lithium to lithium hydroxide?
Conversion of Lithium Carbonate to Lithium Hydroxide
By slurrying lithium carbonate with calcium hydroxide in water at room temperature, it can be converted to lithium hydroxide. After filtering out the calcium carbonate by-product, the lithium hydroxide is purified by crystallization.
