Abstract
The present invention relates to a cathode material of Lithium-Nickel-Cobalt-Aluminum composite oxide, a method of fabricating the same, and a lithium ion battery including the same. The composite cathode material has a core-shell structure, wherein the core portion is made of LiNiCoAlOwhich is washed with an alcohol and organic acid-mixed solution, wherein 0<x≦0.2, 0<y≦0.1; the shell is metal oxide layer. In the present invention, the composite cathode material is fabricated by a combined method, wherein the base material is washed with an alcohol and organic acid-mixed solution and the shell layer material is coated by spray drying. The composite cathode material of the present invention has low content of lithium impurities and excellent high-temperature cycling and storage performance.
