| 摘 要： | The powder of LiNi1/3Co1/3Mn1/3O2 were prepared directly without artificial grinding and washing by a eutectic molten-salt mixture (0.38LiOH·H2O-0.62LiNO3) method. According to this method, the eutectic molten-salt mixture was self-mixed with precursor thoroughly at low temperature, and then sintered at a certain temperature. The tap-density of the powder obtained was 2.87 g·cm-3. The well-layered 琢-NaFeO2 structure and regular morphology were confirmed by X-ray diffraction (XRD) and scanning electronmicroscopy (SEM).XPSstudies showed that the predominant oxidation states of Ni, Co, andMn in the compound were 2+, 3+, and 4+, respectively. Cathodic behaviour was examined by charge-discharge cycling. The synthesized powder showed a reversible capacity of 160 mAh·g -1 at a specific current of 0.2C in the rang 3.0-4.3 V up to 50 cycles without noticeable capacity-fading.
