This article reports for the first time ultrafast automatic flame synthesis of high-quality LiCoO2 in open-air conditions as a cathode material for Li-ion batteries. This synthetic method offers the advantages of simplicity, energy, and time saving, as well as low cost with better electrochemical performance than the commercial LiCoO2. The reported method provides the opportunity to develop the scheme, to produce not only LiCoO2 but also commercially available isomorphs of lithium metal oxides as cathode materials beyond laboratory-scale limitations. The entire procedure is completed within 30–50 min, which is the easiest way to obtain LiCoO2 among the reported procedure so far. It can be found that the automatic flame-synthesized LiCoO2 has a better crystal structure and higher specific discharge capacity than the commercial LiCoO2 at all C rates, particularly at higher C rates.
