n flowing. The XRD pattern of the sample prepared under the above condition could be identified by a typical Рstructure of hexagonal α-NaFeO2 type. The SEM micrograph of LiNi0.8Co0.1Mn0.1O2 showed that a large number of spherical primary Рparticles with an average size of about 500∼800 nm piled loosely to form quasi-spherical secondary particles. Electrochemical Рmeasurements showed that it delivered an initial discharge capacity of 168.6 mA⋅h/g during the first charge and discharge cycle, and the Рfirst coulombic efficiency was 90.5%, and the discharge capacity in the 20th cycle was 161.7 mA⋅h/g. The material would be potential Рcathode material for Li-ion battery. РKey words: lithium ion battery; cathode material; lithium nickel cobalt manganese oxide; layered structure; co-precipitation
