Method for producing battery grade lithium hydroxide monohydrate KU Leuven
The invention relates to processes for refining lithium chloride comprising the steps of : 1) dissolving a solid composition comprising less than 98 % (w/w) lithium chloride in an organic solvent thereby selectively dissolving lithium chloride; 2) adding an alkali metal hydroxide solubilised in an organic solvent; 3) optionally further purifying lithium chloride in the organic solution by non-aqueous ion exchange; and 4) removing the organic solvent.
