What is the basic information of lithium compounds?

Lithium Carbonate:
Lithium carbonate is an inorganic compound with the chemical formula Li2CO3. It has a molar mass of 73.9 g/mol, and the lithium element has a mass fraction of 18.79%. It appears as a colorless monoclinic crystal or white powder with no taste. It has a density of 2.11 g/cm3 and a melting point of 723°C. Lithium carbonate decomposes upon melting. It is soluble in dilute acids and slightly soluble in water with poor solubility. It is insoluble in alcohols and acetone. Lithium carbonate does not deliquesce and is stable in the air. It should be stored in a well-ventilated and dry place, protected from rain or water immersion. Avoid contact with acidic substances.

Lithium Hydroxide:
Lithium hydroxide is an inorganic compound with the chemical formula LiOH and is commonly found as a monohydrate LiOH·HzO. It is a white crystalline powder with strong alkalinity and does not burn, but it is highly corrosive. It has a density of 1.46 g/cm3. It has a melting point of 462°C and decomposes at a boiling point of 924°C. It is soluble in water and slightly soluble in alcohols.


(1) Bulk Packaging: Available in 250 kg, 350 kg, 500 kg, and 800 kg packages, with 500 kg per bag being the mainstream option, known as a metric ton bag. Typically, it is double-layered packaging, with an outer woven bag and an inner plastic film bag. The inner bag is sealed with a zipper or heat sealing, and the outer bag has strong stitching.

(2) Small Packaging: Primarily offered in two options, 20/25 kg per bag.


(1) For long-term storage, place the bags on wooden pallets, and wrap and secure the entire pallet with stretch film. Each pallet contains 1 ton of product. Storage does not require special conditions, but it is important to take measures to prevent moisture.

(2) Shelf Life: Properly stored, industrial-grade and battery-grade lithium carbonate can be stored for 2-3 years. However, physical properties may change after one year or more, such as clumping due to moisture absorption. Clumped material can be reprocessed into powder form, which has relatively stable properties. The cost of reprocessing into powder is a few hundred dollars per ton, which is lower compared to the price of lithium carbonate.
