摘要：
Li1.2Mn0.54Ni0.195Co0.065O2 (x+y=0.26, and x:y=1:1, 1:2, 2:1, 1:3, 3:1) was synthesized by aerogel with urea as chelating agent. The physical and electrochemical properties of the cathode materials were investigated through X-ray diffraction, scanning electron microscopy, cyclic voltammetry, and electrochemical impedance spectroscopy analyses as well as and charge/discharge tests. Results showed that samples with different Ni/Co ratios crystallized well and showed a layered structure. The sample, Li1.2Mn0.54Ni0.195Co0.065O2 (x:y=3:1), delivered a high discharge capacity of 313 mA h g(-1) at 20 mA g(-1) and exhibited excellent cycle performance after 50 cycles, with a capacity of 247 mA h g(-1) at 100 mA g(-1).
