  • Publication number: 20230183092
    Abstract: Various lithium cobalt oxides materials having a chemical formula of LixCoyOz, and method and apparatus of producing the various lithium cobalt oxides materials are provided. The method includes adjusting a molar ratio MLiSalt:MCoSalt of a lithium-containing salt, and a cobalt-containing salt within a liquid mixture to be equivalent to a ratio of x:y, drying a mist of the liquid mixture in the presence of a gas to form a gas-solid mixture, separating the gas-solid mixture into one or more solid particles of an oxide material, and annealing the solid particles of the oxide material in the presence of another gas flow to obtain crystallized particles of the lithium cobalt oxide material. The process system has a mist generator, a drying chamber, one or more gas-solid separator, and one or more reactors.
