Spherical Li[Ni1/3Co1/3Mn1/3]O-2 cathode material for lithium-ion batteries was prepared by salvolatile coprecipitation. The obtained Li[Ni1/3Co1/3Mn1/3]O-2 was characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), particle size distribution (PSD), atomic absorption spectroscopy (AAS), and galvanostatic charge-discharge cycling. The XRD pattern of Li[Ni1/3Co1/3Mn1/3]O-2 revealed a well-ordered hexagonal layered structure with low cation mixing. Spherical secondary particles and spherical primary particles can be identified from SEM observations. Reasonable size distribution of secondary particles was confirmed by PSD measurement. The initial discharge capacity of the Li[Ni1/3Co1/3Mn1/3]O-2 cathode was 163.3 mAh g(-1) in the voltage range of 2.8-4.3 V at 30 degrees C, and 95.7% of the initial capacity was retained after 30 charge-discharge cycles.
