Industrial Grade/Battery Grade/Micropowder Battery Grade Lithium
Lithium Hydroxide is generated by the reaction of lithium metal or LiH with H2O, and the stable chemical form at room temperature is nondeliquescent monohydrate LiOH.H2O.
Lithium Hydroxide Monohydrate is an inorganic compound with the chemical formula LiOH x H2O. It is a white crystalline material, which is moderately soluble in water and slightly soluble in ethanol. It has a high tendency to absorb carbon dioxide out of the air.
UrbanMines’ Lithium Hydroxide Monohydrate is an Electric Vehicle grade that is suitable for the highest standards of electromobility: very low impurity levels, low MMIs.

What is Lithium Hydroxide used for?
1. To produce different lithium compounds and lithium salts：
Lithium Hydroxide is used in the manufacturing of lithium salts of stearic and additional fatty acids. In addition, lithium hydroxide is mainly used to produce different lithium compounds and lithium salts, as well as lithium soaps, lithium-based greases and alkyd resins. And it is widely used as catalysts, photographic developers, developing agents for spectral analysis, additives in alkaline batteries.
2. To produce cathode materials for lithium-ion batteries：
Lithium Hydroxide is mainly consumed in the production of cathode materials for lithium-ion batteries such as lithium cobalt oxide (LiCoO2) and lithium iron phosphate. As an additive for alkaline battery electrolyte, lithium hydroxide can increase the electric capacity by 12% to 15% and battery life by 2 or 3 times. Lithium hydroxide battery grade, with low melting point, has been prevailingly accepted as a better electrolyte material in NCA, NCM lithium-ion battery manufacture, which enables nickel-rich lithium batteries much better electric properties than lithium carbonate; while the latter remains the priority choice for LFP and many other batteries so far.
3. Grease：
A popular lithium grease thickener is lithium 12-hydroxystearate, which produces a general-purpose lubricating grease due to its high resistance to water and usefulness at a range of temperatures. These are then used as a thickener in lubricating grease. Lithium grease has multi-purpose properties. It has high temperature and water resistance and it can also sustain extreme pressures, making it suitable for various industries. It is especially used in the automotive and automobile industry.
4. Carbon dioxide scrubbing：
Lithium Hydroxide is used in breathing gas purification systems for spacecraft, submarines, and rebreathers to remove carbon dioxide from exhaled gas by producing lithium carbonate and water. They are also used as an additive in the electrolyte of alkaline batteries. It’s also known to be a carbon dioxide scrubber. The roasted solid lithium hydroxide can be used as a carbon dioxide absorbent for crews in spacecraft and submarines. Carbon dioxide can be easily absorbed in gas containing water vapor.
5. Other uses：
It is also used in ceramics and some Portland cement formulations. Lithium hydroxide (isotopically enriched in lithium-7) is used to alkalize the reactor coolant in pressurized water reactors for corrosion control.
