摘　　要：对近几年有关层状Li-Co-Ni-Mn-O作为锂离子电池新型正极材料的研究进行了系统分析。比较了不同的合成方法及组成对材料性能的影响。其中LiNi1/3Co1/3Mn1/3O2和LiNi0.6CO0.2Mn0.2O2是比较好的。对层状Li-Co-Ni-Mn-O性能的改进提出了进一步改进的措施;认为应该发展低温合成方法,优化和降低Co和Ni的含量,掺杂一种或多种高价金属元素是很有前途的方法。A review was composed for investigations on layered Li-Co-Ni-Mn-O as novel cathode material for Li-ion battery in recent years. Influences of different synthesizing methods and compositions on properties of layered Li-Co-Ni- Mn-O were discussed. Suggestions on measures to improve the properties of layered Li-Co-Ni-Mn-O were given. Low synthesizing temperature, low contents of Co and Ni especially, doping one or more metal elements with high valence would be promising for the material.
