Lithium Carbonate Properties
What is Lithium Carbonate Li2CO3 Powder:
Lithium carbonate is an inorganic compound, chemical formula Li2CO3, molecular weight 73.89, colorless monoclinic crystal, slightly soluble in water and dilute acid, insoluble in ethanol and acetone. The thermal stability of carbonate is lower than that of other elements of the same group in the periodic table, and it is not deliquescent in the air. It can be obtained by adding sodium carbonate into lithium sulfate or lithium oxide solution. The water solution can be converted into acid salt by adding carbon dioxide, and then boiled for hydrolysis. It is used as raw material for ceramics, glass, ferrite, etc., and its components are sprayed with silver paste. It is used in medicine to treat depression.
Lithium carbonate has a crystal structure in which lithium and carbonate ions are arranged alternately. Due to the large radius of carbonate ions, lithium ions have a high mobility in the crystal, which is one of the important advantages of lithium carbonate as a negative electrode material for lithium batteries.
Lithium carbonate, with a molecular weight of 73, has a high electronegativity and can provide a strong lithium ion attraction. At the same time, lithium carbonate's molecular structure contains oxygen and carbon atoms, making it easy to oxidize in the air. Hence, it needs to be kept in a sealed container.

How is Lithium Carbonate Li2CO3 Powder produced?
1. Comprehensive use of brine: the lithium containing solution of brine after extracting barium chloride is added with soda ash to remove calcium and magnesium ions in the solution, hydrochloric acid is added for acidification, sodium chloride is removed by evaporation, and then iron is removed. Then excessive soda ash is added to precipitate lithium carbonate, and then washed, centrifuged and dried to produce lithium carbonate finished products. 

2. Lime sintering method: spodumene concentrate (generally containing 6% lithium oxide) and limestone are proportioned at a weight ratio of 1: (2.5~3). Mix and grind, sinter at 1150~1250 ℃ to produce lithium aluminate and calcium silicate, grind and crush them through wet grinding, leach lithium hydroxide with washing solution, and then filter the residue back or wash to remove the residue. The leaching solution is evaporated and concentrated, then add sodium carbonate to produce lithium carbonate, and then centrifugally separate and dry to produce lithium carbonate products. 

3. Using lithium hydroxide and carbon dioxide as raw materials to produce high-purity lithium carbonate, or lithium sulfate and sodium carbonate as reactants, but lithium carbonate is easily soluble in other salt solutions, so the yield is not very high, generally about 75%, and the product also contains a small amount of lithium sulfate. 

4. Sulfuric acid method: the molten spodumene is reacted with sulfuric acid, purified and then reacted with sodium carbonate. 

5. Lime method: calcined spodumene is reacted with lime milk, purified and then reacted with sodium carbonate. 

6. By-production method: extracted from mother liquor containing lithium after preparing barium chloride from well brine. 

7. Take industrial lithium hydroxide as raw material, heat water to dissolve it, filter the insoluble matter, inject clean carbon dioxide gas into the filtrate while it is hot until no precipitation is generated, filter it while it is hot, dry it, wash it with hot distilled water until it is qualified, and dry it at 110 ℃. Dissolve industrial lithium carbonate in cold water, filter it, boil the filtrate, stop heating, filter it while it is hot, wash it with hot water, dry it and dry it, and then prepare reagent lithium carbonate.

Application of Lithium Carbonate Li2CO3 Powder:

Improve the energy density and power density of the battery.

As lithium carbonate has a high lithium ion content and good conductivity, it can effectively improve lithium batteries' energy density and power density. Lithium carbonate can provide more embedded lithium sites in the anode material, thus realizing higher capacity and faster charging and discharging speed. Meanwhile, lithium carbonate's conductivity can improve the electrode material's electrical conductivity, further optimizing the charging and discharging performance of the battery.


Improvement of battery cycle life and stability

Lithium carbonate has high chemical and structural stability, which can effectively improve lithium batteries' cycle life and stability. In the charging and discharging process, lithium carbonate can maintain a stable structure, avoiding phenomena like capacity degradation and structural rupture. At the same time, the chemical stability of lithium carbonate can resist the erosion of various chemical substances, thus ensuring the long life and stability of the battery.


Improve the safety performance of the battery.

Lithium carbonate has high thermal and electrical conductivity, which can effectively improve the safety performance of the battery. Under high-temperature conditions, lithium carbonate can quickly transfer heat to the surrounding environment to avoid battery failure or burning due to overheating. At the same time, lithium carbonate has good electrical conductivity, which can improve the electrical stability of the battery and avoid battery explosion or fire due to short circuits and other reasons.


Application in composite electrode materials

Lithium carbonate can be compounded with other materials to prepare composite electrode materials, thereby improving the overall performance of lithium batteries. For example, compounding lithium carbonate with conductive polymers, carbon nanotubes, graphene, and other materials can further improve the conductivity and lithium-embedded performance of the electrode materials, thus realizing more efficient charging and discharging. In addition, compounding lithium carbonate with metal oxides, sulfides, and other materials can further improve the capacity and cycling stability of the electrode materials, thereby realizing a longer battery life.


Lithium carbonate, as a new type of anode material for lithium batteries, has the advantages of high energy density, good cycle life, and safety. It has physicochemical properties such as high lithium ion content, good electrical conductivity, and chemical stability, which can be applied in high-energy and high-power-density lithium batteries. At the same time, lithium carbonate can be compounded with other materials to prepare composite electrode materials to improve the comprehensive performance of lithium batteries. Lithium carbonate anode materials will be more widely used with the continuous development of lithium battery technology and the continuous expansion of application areas.
