摘　　要：采用微通道反应器法直接合成锂离子电池正极材料。并且采用XRD、FESEM、FT-IR和电化学测试系统对样品进行一系列的表征。实验结果表明,流速为100mL/min,反应物浓度为0.1mol/L时制备得到了分散比较均匀的样品,该正极材料具有良好的循环性能和倍率性能,在0.1C倍率下首次放电比容量达到136.6mAh/g。在0.4C倍率下首次放电比容量为93.73mAh/g,50个循环之后,容量基本无衰减。A anode material was synthesized by using microreactor.The sample was characterized by XRD,FESEM,FT-IR spectra and electrochemical test.The results showed that the sample prepared with 0.1mol/L reactant synthesized at100mL/min had a narrow particle size distribution.Its electrochemical performance as an anode material for lithium ion batteries was tested by capacity measurement.Rate capacity and cycling performance of the product were very satisfactory.The specific capacities of sample could reach 136mAh/g at 0.1Crate.The sample could deliver specific capacities of 93.73mAh/g at0.4Crate and without obvious capacity fade after 50 cycles.
