Lithium Cobalt Oxide
Basic information:
Lithium cobalt oxide, with the chemical formula of LiCoO2, is an inorganic compound, which is generally used as the positive electrode material of lithium ion battery. Generally used for lithium ion two battery cathode material, liquid phase synthesis process, it uses polyvinyl alcohol (pVA) or polyethylene glycol (pEG) aqueous solution as solvent, lithium salt and cobalt salt are dissolved in pVA or pEG aqueous solution respectively. After mixing, the solution is heated to form gel, then the gel is decomposed and then calcined at high temperature. Lithium cobaltate powder is obtained by sieving.
The lithium cobaltate can inhibit the polarization of the battery, reduce the heat effect, improve the multiplying power performance, reduce the internal resistance of the battery, obviously reduce the dynamic internal resistance increase in the cycle process, improve the consistency and prolong the cycle life of the battery; It is a popular material to improve the processing performance of lithium iron phosphate and lithium titanate materials.
Its appearance is gray black powder. It is a strong oxidant in acidic solution, which can oxidize CI - to Cl2 and Mn2 + to MnO4 -. The redox potential in acidic solution is weaker than that of ferrate, but much higher than that of permanganate.
Characteristics of lithium cobalt oxide:
1. Superior electrochemical performance
2. Excellent processability
3. High compaction density helps to improve the volume specific capacity of the battery
4. The product has stable performance and good consistency
