Composite cathode active materials comprising a composite oxide and an acid treated with an organic solvent are provided. The composite cathode active materials are prepared by treating mixtures of nickel-based composite oxides and organic acids with organic solvents. The active materials suppress gelation of the electrode slurries for a long period of time, even when the active materials are mixed with fluorine-based polymers, by decreasing the basicity of the slurries and the amount of lithium present on the surfaces of the active materials. As a result, electrode slurries having high stability can be prepared. Cathodes and lithium batteries comprising the slurries have excellent charge-discharge characteristics, including high capacity and excellent high rate discharge characteristics.

Cathode active material, method of preparing the same, and cathode and lithium battery applying the material

A cathode active material is prepared by mixing a transition metal compound and a lithium compound in a molar ratio of 1:1.0-1:1.2 and thermally treating the mixture while supplying COand Oin a ratio of partial pressures ranging from 1:0.001-1:1,000, and a lithium battery utilizes the cathode active material. The lithium battery ensures safety against over-charging because an overflow of current may be effectively cut off without reducing discharging capacity and cycle life characteristics.
