It has been, however, a continuing issue that new additional steps should be introduced to commercialize this process. In this work, spray drying was introduced to the existing sol-gel process as a continuous mass production method of the pre-heat treatment precursor materials. The precursors of LiCoO2 and Li Ni0.8Co0.2O2 were continuously produced through spray drying from the solution containing stoichiometric amount of lithium, cobalt, and nickel sources as well as a chelating agent. The process variables, such as pH of the starting solution, spray drying conditions, and calcination conditions were optimized. The XRD pattern for the synthesized material indicated a good crystallinity with a layered structure. 한국전기화학회 Synthesis and Characterization of Cathode Materials for the Lithium Secondary Batteries by Spray Drying Method Article 2 전기화학회지, v.8, no.1, pp.42 - 46 전기화학회지 8 1 42 46 kci ART000942739 cathode sol-gel spray drying LiCoO2 LiNi0.8Co0.2O2 continuous cathode sol-gel spray drying LiCoO2 LiNi0.8Co0.2O2 continuous
