Lithium Hydroxide (LiOH)

CAS 1310-65-2 · Formula HLiO · MW 24.0 g/mol

A strong lithium base that anchors high-performance greases, scrubs CO2, and feeds battery cathodes. It is the precursor for lithium-soap lubricating greases, a carbon-dioxide absorbent in confined-atmosphere air purification, a cathode-material precursor for lithium-ion batteries, and an additive in alkaline storage batteries; it is also used in photographic developers and alkyd paints.

Full Description

Lithium hydroxide (LiOH, CAS 1310-65-2) is a strong inorganic base. It is the precursor for lithium-soap lubricating greases, a carbon-dioxide absorbent in confined-atmosphere air purification, a cathode-material precursor for lithium-ion batteries, and an additive in alkaline storage batteries; it is also used in photographic developers and alkyd paints.

Frequently Asked Questions

What is lithium hydroxide used for?

Lithium hydroxide (LiOH, CAS 1310-65-2) is a strong inorganic base used as the precursor for lithium-soap lubricating greases, a carbon-dioxide absorbent in confined-atmosphere air purification, a cathode-material precursor for lithium-ion batteries and additive in alkaline storage batteries, and in alkyd paints and photographic developers.

Does lithium hydroxide absorb CO2?

Yes. Lithium hydroxide reacts with carbon dioxide to form lithium carbonate and water, which is why it is used as a CO2 scrubbing absorbent in confined-atmosphere air-purification systems such as submarines and spacecraft.

What is the formula for lithium hydroxide?

The formula is LiOH (listed as HLiO), CAS 1310-65-2. It is commonly supplied as the monohydrate, LiOH·H2O (CAS 1310-66-3); specify anhydrous or monohydrate when ordering.

How does lithium hydroxide ship under DOT regulations?

Lithium hydroxide solution is assigned UN 2679 (LITHIUM HYDROXIDE, SOLUTION) as a corrosive material. Shipping classification, packaging, and labeling follow the SDS and applicable transport regulations; confirm form (solution vs. solid) when arranging freight.

Does RawSource supply lithium hydroxide in bulk?

RawSource distributes lithium hydroxide in bulk industrial volumes under HS code 2825.20. A Certificate of Analysis and Safety Data Sheet ship with each order; request both with a bulk quote, and specify anhydrous or monohydrate form and target volume.
