A novel synthesis method of carbon-coated LiNi1/3Mn 1/3Co1/3O2 cathode material for lithium-ion battery was reported. The carbon coating was produced from a precursor, glucose, by microwave-pyrolysis method. The prepared powders were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray fluorescence (XRF) and charge/discharge tests. XRD results indicate that the carbon coating does not change the phase structure of LiNi1/3Mn1/3Co 1/3O2 material. SEM results show that the surface of spherical carbon-coated material becomes rough. Electrochemical performance results show that the carbon coating can improve the cycling performance of LiNi1/3Mn1/3Co1/3O2. The specific discharge capacity retention of the carbon-coated LiNi1/3Mn 1/3Co1/3O2 reached 85.0%-96.0% at the 50th cycle at 0.2C rate, and the specific discharge capacity retention is improved at a high rate.
