Lithium Hydroxide
Lithium hydroxide (Lithium hydroxide) is a white monoclinic fine crystal or powdery solid state. It has two forms: anhydrous and monohydrate. It belongs to the monoclinic crystal system or the tetragonal crystal system, which is strongly alkaline and corrosive. It can absorb carbon dioxide and moisture in the air. Soluble in water, slightly soluble in ethanol, insoluble in ether.
Lithium hydroxide is widely used in new energy vehicles, petroleum, chemical industry, light industry, nuclear industry, metallurgy, glass, ceramics and other fields. It is an important lithium chemical raw material and is often used to prepare lithium salts and lithium soaps (lithium soaps). ), lithium battery cathode material and lithium-based grease, can also be used as electrolyte for alkaline storage batteries, lithium bromide refrigerator absorbing liquid, analytical reagents, photographic developer, etc.
Battery-grade lithium hydroxide monohydrate: mainly used to prepare ternary cathode materials for lithium-ion batteries such as NCM and NCA.
Industrial-grade lithium hydroxide monohydrate: Mainly used to prepare lithium salt and lithium-based grease, and can also be used as electrolyte for alkaline storage batteries, lithium bromide refrigerator absorbing fluid, and glass and ceramic additives.
Anhydrous Lithium Hydroxide: It is mainly used to prepare high nickel ternary cathode materials, and can also be used as carbon dioxide absorbent, analytical reagent, photographic developer, etc.
