摘要	Li-rich solid solution cathode material Li[Li0.2Ni0.2Mn0.6]O-2 was synthesized by a sol-gel method and subsequent solid-state sintering process, using LiOH center dot H2O, Mn(CH3COO)(2)center dot 4H(2)O and H3COO)(2)center dot 4H(2)O as raw materials, and citric acid (CA) and ethylene diamine tetraacetic acid (EDTA) as chelating agents, respectively. The as-synthesized materials were characterized by X-ray diffraction, scanning electron microscope and Laser Particle Size Analyzer, and the electrochemical properties of materials were investigated. The material using CA as chelating agent showed higher capacity and better rate performance than that using EDTA as chelating agent. The half-cell of Li/Li[Li0.2Ni0.2Mn06]O-2 using CA as chelating agent delivered a charge specific capacity of 324 mAh.g(-1) with an initial efficiency of 82% at a current density of 18 mA.g(-1) between 2.0 and 4.8 V, and retained the reversible capacity of 120 mAh.g(-1) even at a high current density of 180 mA.g(-1)
