Synthesis and characterization of the nanosized Li[Ni1/3Co1/3Mn1/3]O2

Abstract Nanoparticles of Li[Ni 1/3 Co 1/3 Mn 1/3 ]O 2 with average diameter less than 100 nm are synthesized in the ethanol by a coprecipitation method. The sample is characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM) and charge–discharge test. The results show that the material has initial discharge capacity of 165.7 mAh g −1 in the voltage range of 3.0–4.3 V under a current density 0.2 C and excellent cyclability.
