Lithium-ion batteries Lithium hydroxide is mainly consumed in the production of
cathode materials for
lithium-ion batteries such as
lithium cobalt oxide () and
lithium iron phosphate. It is preferred over
lithium carbonate as a precursor for
lithium nickel manganese cobalt oxides.
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.
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: : or : The latter, anhydrous hydroxide, is preferred for its lower mass and lesser water production for respirator systems in spacecraft. One gram of anhydrous lithium hydroxide can remove 450 cm3 of carbon dioxide gas. The monohydrate loses its water at 100–110 °C.
Precursor Lithium hydroxide, together with
lithium carbonate, is a key intermediates used for the production of other lithium compounds, illustrated by its use in the production of
lithium fluoride: Lithium hydroxide (
isotopically enriched in
lithium-7) is used to alkalize the reactor coolant in
pressurized water reactors for corrosion control. It is good radiation protection against free neutrons. ==Price==
