Advantages of Lithium Cobalt Oxide Cathode Materials

Lithium cobalt oxide, with the chemical formula of LiCoO2, is an inorganic compound.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.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.
