Abstract: The present disclosure provides a process for the production of a cathode active material complex which is used for a lithium secondary battery, comprising the steps of: mixing a lithium metal phosphate with a solvent to prepare a first precursor; mixing the first precursor with a graphene oxide to prepare a second precursor solution; forming droplets from the second precursor solution; and making the droplets into a powder; wherein the formation of the powder is performed by spray pyrolysis method.
