Abstract

A novel synthesis method of carbon-coated LiNi_1/3Mn _1/3Co_1/3O₂ 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 LiNi_1/3Mn_1/3Co _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 LiNi_1/3Mn_1/3Co_1/3O₂. The specific discharge capacity retention of the carbon-coated LiNi_1/3Mn _1/3Co_1/3O₂ 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.
