Lithium hydroxide

Lithium hydroxide is an inorganic chemical compound with the formula HLiO and CAS number 1310-65-2. This alkali metal hydroxide has a molecular weight of 24 g/mol and appears as a white crystalline solid. It is highly soluble in water and exhibits strong basic properties. Lithium hydroxide is commonly available in both anhydrous and monohydrate forms, with the latter being more stable under normal conditions.

Lithium hydroxide is a white crystalline solid that is odorless and highly hygroscopic. It readily dissolves in water, forming a strongly alkaline solution with a pH above 12. The compound has a relatively low molecular weight of 24 g/mol and melts at approximately 462°C. It demonstrates excellent thermal stability and is non-volatile at room temperature, making it suitable for various industrial applications.

Lithium hydroxide is primarily used in lithium-ion battery production as a cathode material precursor, particularly for electric vehicle batteries. It serves as a key raw material in manufacturing lithium carbonate and other lithium compounds. Additional applications include CO2 absorption systems in submarines and spacecraft, ceramic and glass manufacturing, and as a catalyst in certain chemical processes. The growing electric vehicle market has significantly increased demand for this compound.

Lithium hydroxide requires careful handling due to its corrosive alkaline nature. Personnel should wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Ensure adequate ventilation in work areas and avoid generating dust. In case of spills, neutralize with dilute acid and clean thoroughly. Store handling equipment separately from incompatible materials and maintain emergency shower facilities nearby.

Lithium hydroxide should be stored in tightly sealed containers in a cool, dry environment away from moisture and humidity. Keep containers in well-ventilated areas and protect from direct sunlight and heat sources. Store separately from acids, organic materials, and aluminum to prevent dangerous reactions. Use moisture-proof packaging and consider desiccant materials to maintain product quality and prevent caking or degradation.

Lithium hydroxide contact requires immediate action due to its corrosive properties. For skin contact, immediately flush the affected area with plenty of water for at least 15 minutes and remove contaminated clothing. In case of eye contact, rinse continuously with clean water and seek medical attention immediately. If inhaled, move the person to fresh air and provide respiratory support if needed. Always consult medical professionals for proper treatment.

Lithium hydroxide disposal must comply with local and national waste regulations as it is classified as hazardous waste. Neutralize small quantities carefully with dilute acid under controlled conditions before disposal. Large quantities should be handled by licensed waste management companies. Never dispose of lithium hydroxide in regular trash or pour down drains, as it can cause environmental damage and infrastructure corrosion.

Lithium hydroxide is classified under ADR Class 8 (corrosive substances) with Packing Group II, indicating moderate danger level. Transport requires appropriate UN-specification packaging designed for corrosive materials. Vehicles must display proper hazard labels and carry required documentation including safety data sheets. Drivers need ADR certification for dangerous goods transport. Ensure packages are properly sealed and protected from moisture during transit.

Lithium hydroxide is regulated under various European chemical legislation including REACH registration requirements and CLP classification standards. It is not currently listed as a Substance of Very High Concern (SVHC). Transport regulations classify it as a dangerous good under ADR Class 8. Users must comply with workplace safety regulations and maintain proper safety data sheets for occupational health and safety compliance.
