Li[Ni1/3Co1/3Mn1/3]O2 was synthesized by modified combustion method and effect of calcination temperature on characteristics was investigated. The cycle of Li[Ni1/3Co1/3Mn1/3]O2 was determined by electrochemical measurements, the microscopic structural features were investigated using Fourier transform infrared spectroscope(FTIR), Scanning Electron Microscopy (SEM), X-ray diffraction (XRD). The results show that the compound has layered structure with hexagonal lattice. With the increase of calcination temperature, the size of primary particle rises. The Li[Ni1/3Co1/3Mn1/3]O2 calcined at 900 oC shows excellent electrochemical performances with large reversible specific capacity of 152 mAhg-1 in the voltage range of 2.75-4.20 V.
