The system finally selected was the COLEX process, with aqueous lithium hydroxide (LiOH) contacted with lithium-mercury amalgam. This process was initially used in the US between 1955 and 1963 in the Y12 plant in Oak Ridge, Tennessee .
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. While classified as a strong base, lithium hydroxide is the weakest known alkali metal hydroxide.
The plant will use Nobian's electrolysers to convert extracted lithium chloride into high-purity lithium hydroxide. With an electrolysis process, Vulcan is able to produce lithium hydroxide with a purity grade of 57.1%, exceeding the 56.5% specification set by battery manufacturers. [27] For this process, Vulcan also developed a new sorbent ...
The second step then involves bipolar electrodialysis which splits a salt into its acid and base components. In the case of lithium chloride, it splits into lithium hydroxide and hydrochloric acid." [1] The lithium separation technology is assembled into processing units, which, in turn, are integrated in large housing containers.
Lithium carbonate may be converted into lithium hydroxide as an intermediate. In practice, two components of the battery are made with lithium compounds: the cathode and the electrolyte . The electrolyte is a solution of lithium hexafluorophosphate , while the cathode uses one of several lithiated structures, the most popular of which are ...
The Greenbushes mine is the world's largest hard rock lithium mine in terms of reserves, resources, production, and capacity. [5] The facility's operations are made up of the mine and two nearby processing facilities that convert the raw lithium spodumene concentrate into lithium hydroxide before being sold to global battery manufacturers including LG Chem, CATL and Northvolt.

Lithium hydroxide and lithium peroxide are the salts most commonly used in confined areas, such as aboard spacecraft and submarines, for carbon dioxide removal and air purification. Lithium hydroxide absorbs carbon dioxide from the air by forming lithium carbonate, and is preferred over other alkaline hydroxides for its low weight.
