A method of preparing a lithium-nickel-manganese-cobalt composite oxide used as a positive electrode material for a lithium ion battery, comprising first and second steps of sintering a mixture comprising a lithium compound and nickel-manganese-cobalt hydroxide. As a method, the method further comprises adding a binder, a binder solution, or a binder and a binder solution after the first step of sintering, wherein the binder, the binder solution, or the binder and the binder solution and the first step of sintering product The mixture is sintered in a second stage of sintering. The tap density and volume specific capacity of the cathode material lithium-nickel-manganese-cobalt composite oxide produced by the method of the present invention amount to 2.4 g / cm 3 and 416.4 mAh / cm 3 , respectively. In addition, the positive electrode material produced by the method of the present invention has the advantages of high specific capacity and excellent circulation safety.n n n n Lithium Ion Batteries, Anode Materials, Binders, Sintered |
