Lithium hydroxide monohydrate

Lithium hydroxide monohydrate (CAS 1310-66-3) is a high-purity inorganic base used across battery manufacturing, industrial chemistry, and specialty lubrication. Its controlled alkalinity and reactivity profile make it a preferred source of lithium.

In processes where anhydrous forms would introduce handling or reactivity complications, this monohydrate form is preferred. In lithium-ion battery production, it serves as a precursor for cathode active materials.

Consistent purity directly impacts cell performance in materials such as LiNiMnCoO₂ (NMC) and LiNiCoAlO₂ (NCA). Lubricant manufacturers use it to saponify fatty acids, producing lithium-based greases.

These greases outperform conventional soaps in high-temperature and high-load applications. In water treatment, it adjusts pH in closed-loop systems, particularly in nuclear and industrial cooling circuits.

Precise alkalinity control prevents corrosion in these sensitive environments. Pharmaceutical and specialty chemical producers also use it as a catalyst or base in synthesis steps requiring a soluble lithium source.

Lithium hydroxide monohydrate is supplied as a white granular powder or fine powder. Particle size is selected based on dissolution rate requirements, with standard commercial grades including technical and battery-grade.

For pharmaceutical applications, USP-grade material is available to meet strict regulatory requirements. Battery-grade specifications are increasingly the benchmark for procurement in the modern market.

These grades feature tightly controlled limits on sodium, calcium, and sulfate content. This ensures the highest level of performance and stability in advanced chemical manufacturing and energy storage applications.
