摘要：

Submicron LiNi0.6Co0.2Mn0.2O2 as a cathode material for lithium-ion batteries was prepared by a spray drying assisted solid-state method. The crystal structure, morphology and electrochemical properties of LiNi0.6Co0.2Mn0.2O2 were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscope, energy-dispersive spectroscopy and charge-discharge testing. Single-phase layered LiNi0.6Co0.2Mn0.2O2 was obtained. The material delivered a reversible charge/discharge capacity of 179.8 mAh g(-1) at C/10, and showed excellent cycling performance and rate capability. (C) 2011 Acta Materialia Inc.
