Lithium hydroxide

Lithium hydroxide (CAS 1310-65-2, EC 215-183-4, formula HLiO) is an inorganic alkali also referenced as lithium hydrate or lithium hydroxide anhydrous. It carries no assigned E-code. It is commercially available in both monohydrate and anhydrous forms, with the anhydrous grade designated by the same CAS number.

In lithium-ion battery electrolyte production, lithium hydroxide reacts with precursor materials to synthesize high-nickel cathode compounds such as NMC and NCA, directly influencing energy density. In lubricant manufacturing, it saponifies fatty acids to produce lithium-based greases, which retain structural stability across a broad temperature range. It also functions as a pH-regulating agent and antimicrobial buffer in textile processing baths.

Lithium hydroxide is supplied in technical, battery, and pharmaceutical grades, with Ph.Eur.-compliant material available for regulated applications. It falls under REACH registration requirements within the EU (HS code 28252010). Packaging typically includes multi-wall paper sacks, fibre drums, and bulk options depending on grade and volume.
