Lithium Hydroxide

## Lithium Hydroxide (LiOH, CAS 1310-65-2): Key Functions and Uses

1. **Lithium-Ion Battery Cathode Precursor**
Lithium Hydroxide is an important lithium source for manufacturing high-performance lithium-ion battery cathode materials. Battery-grade lithium hydroxide, often supplied as lithium hydroxide monohydrate, is widely used in the synthesis of nickel-rich **NMC** and **NCA** cathodes.

2. **Support for High-Nickel Battery Chemistry**
LiOH enables controlled lithiation during cathode production and is relevant to high-energy-density battery systems for electric vehicles, portable electronics, and stationary energy storage. Final cell performance depends on purity, particle characteristics, calcination conditions, and cathode composition.

3. **Raw Material for Lithium Compounds**
Lithium Hydroxide is used to produce other lithium chemicals, including lithium soaps, lithium salts, lithium fluoride, and specialty inorganic compounds. Its strong alkalinity and high lithium content make it a useful industrial synthesis reagent.

4. **Lithium Grease Manufacturing**
One of its major industrial functions is the production of lithium soaps, especially lithium stearate and lithium 12-hydroxystearate. These soaps act as thickeners in multipurpose lubricating greases used for automotive, industrial, mechanical, and high-temperature applications.

5. **Carbon Dioxide Absorbent**
LiOH reacts with carbon dioxide and is used in selected breathing-gas purification systems, including spacecraft, submarines, rebreathers, and enclosed environments. Its application depends on system design, capacity, moisture control, and strict safety requirements.

6. **Glass, Ceramics, and Metallurgical Applications**
Lithium Hydroxide may be used in glass, ceramic, enamel, metallurgy, and specialty-material formulations. Lithium addition can influence melting behavior, thermal expansion, chemical durability, and processing characteristics.

7. **Chemical Processing and pH Adjustment**
CAS 1310-65-2 functions as a strong inorganic base in chemical synthesis, neutralization, pH adjustment, and process chemistry. It can support the preparation of lithium-containing intermediates and controlled alkaline reactions.

8. **Quality, Procurement, and Safety Considerations**
When sourcing Lithium Hydroxide 1310-65-2, buyers should verify anhydrous or monohydrate form, battery-grade or industrial-grade purity, carbonate content, trace metals, moisture level, particle size, packaging, and certificate of analysis. Useful SEO keywords include **Lithium Hydroxide, LiOH, CAS 1310-65-2, battery-grade lithium hydroxide, NMC cathode precursor, NCA cathode material, lithium grease, CO₂ absorbent, and lithium compound precursor**. LiOH is corrosive and moisture-sensitive; users must follow the supplier’s Safety Data Sheet, appropriate protective measures, and applicable regulations.
