  • METHOD OF PREPARING COBALT AND LITHIUM ION-COATED NICKEL AND MANGANESE-BASED CATHODE MATERIAL
    Publication number: 20100068376
    Abstract: A method of preparing a cobalt and lithium ion-coated nickel and manganese-based cathode material, including at least: (a) coating a layer of cobalt hydroxide on a substrate of Ni0.5Mn0.5(OH)2 to yield y(Ni0.5Mn0.5(OH)2)·(1-y)(Co(OH)2) (0.2?y?0.8), (b) adding Lithium, and (c) sintering at 750-1000° C. for 8-24 hrs to yield LiNi0.5-xCo2xMn0.5-xO2 (0.03<x?0.4). The method is easy for practice and suitable for mass production, and the cathode material prepared by the method, i.e., LiNi0.5-xCo2xMn0.5-xO2 (0.03<x?0.4) features high specific capacity, stable cycle performance, and low cost.
