Lithium hydroxide monohydrate (LiOH·H2O) is a versatile chemical with several important industrial and technical uses. Here are the main ones explained clearly:
1. Battery Manufacturing (Most Important Use)
• Widely used in lithium-ion batteries, especially for electric vehicles (EVs).
• It helps produce cathode materials like lithium nickel manganese cobalt oxides (NMC).
• Preferred over lithium carbonate for high-performance batteries because it improves energy density and lifespan.
2. Grease Production
• Used to make lithium-based greases.
• These greases are:
• Heat-resistant
• Water-resistant
• Common in automotive and industrial lubricants.
3. Carbon Dioxide Absorption
• Absorbs CO2 effectively, forming lithium carbonate.
• Used in:
• Submarines
• Spacecraft life-support systems
• Helps maintain breathable air
