摘要 采用乙醇共沉淀法制备纳米Li[Ni1/3Co1/3Mn1/3]O2材料。采用XRD和SEM对合成材料进行了表征。结果表明:合成材料的粒径为纳米级,平均粒径可达60 nm,此种方法合成材料具有较好的层状结构和较低的阳离子混排程度。在2.8～4.3 V(vs Li/Li+)条件下进行充放电测试,结果表明材料具有较好的电化学性能,尤其在高倍率下(10 C),材料的放电性能可以达到大功率用电设备的要求。 The nano Li[Ni1/3Co1/3Mn1/3]O2 powder was synthesized via co-precipitation method with ethanol.The synthesized materials were characterized by XRD and SEM.The results indicated that the average diameter of the nanoparticles was 60 nm.The Li[Ni1/3Co1/3Mn1/3]O2 powders had layered hexagonal structure with low cation mixing.Galvanostatic charge-discharge tests between 2.8 V and 4.3 V（vs Li/Li＋） confirmed the Li[Ni1/3Co1/3Mn1/3]O2 electrode had good electrochemical properties,especially the high rate discharge capability such as 10 C,which make it meet the requirement for high power application.
