摘要

The lithium rich cathode materials xLi ₂MnO ₃·(1-x)Li[Ni _1/3Mn _1/3Co _1/3]O ₂ (x=0.4, 0.5, 0.6) were successfully synthesized via sol-gel method with calcination in air. The transition metal acetate, lithium acetate, and citric acid were used as raw materials. The as-prepared materials were characterized by X-ray diffraction (XRD), scaning electron microscopy (SEM), and electrochemical tests. The material 0.5Li2MnO3· 0.5LiNi _1/3Mn _1/3Co _1/3]O ₂, which was obtained after calcination at 900 °C for 12 h, exhibited fine microstructures and good electrochemical performance. When cycled at 2.0-4.8 V with a current density of 20 mA·g ^-1 at room temperature, 0.5Li ₂MnO ₃·0.5LiNi _1/3Mn _1/3Co _1/3]O ₂ delivered a initial discharge specific capacity of 260.0 mAh·g ^-1, and maintained a capacity of 244.7 mAh·g ^-1 after 40 cycles (capacity retention 94.12%).
