摘　　要：综述了近几年锂离子电池正极材料层状三元过渡金属氧化物LiCo_xNi_yMn_(1-x-y)O_2的研究进展,重点讨论了综合性能优异的LiCo_(1/3)Ni_(1/3)Mn_(1/3)O_2的电化学性能、结构、制备方法以及存在的不足,LiCO_(1/3)Ni_(1/3)Mn_(1/3)O_2与其它商业化正极材料相比具有高容量、热稳定性好、高倍率放电等诸多优异的性能,若能解决循环、存放等问题,将有望成为新一代锂离子电池正极材料。The progress in recent research on three-element transition metal oxides LiCox Niy Mn1-x-y O2 is reviewed, which are used as cathode materials for Li-ion batteries. The electrochemical performances, structure, synthesis methods, and some disadvantages of these materials of LiCo1/3Ni1/3Mn1/3O2 are discussed in detail. LiCo1/3Ni1/3Mn1/3O2 materials have many good properties such as higher capacity, improved thermal stability, better rate capacity, and so on, compared with other commercial cathode materials. It will be a new promising cathode material for Li-ion battery if the problems in cycle,storage and other properties are solved.
