Abstract: Systems and methods are described for producing lithium hydroxide from lithium chloride and sodium chloride through an electrolysis process. A solution of lithium hydroxide and sodium hydroxide may be produced through electrolysis of a lithium chloride and sodium chloride solution. Lithium hydroxide in the produced solution may then be crystallized and filtered out to produce substantially pure lithium hydroxide crystals.
