Zusammenfassung:Disclosed is a manufacturing method of a cathode active material. In order to manufacture a cathode active material, a reaction solution is manufactured by mixing source materials in a polyol solvent, and combusted to manufacture first cathode active material powder. The first cathode active material powder is coated with a flammable organic solution and combusted to manufacture second cathode active material powder. The cathode active material manufactured according to the present invention has improved capacity and crystallinity.
