摘　　要：高镍正极材料以其高容量,环境友好等优异的综合性能,受到了广泛关注。高镍正极材料在通过提高镍含量来提高能量密度的同时,通常会伴随着钴含量的降低。钴元素对材料的结构稳定性有重要影响,钴含量的降低,材料的本征特点和反应机理都会发生明显的改变,所以其制备工艺,掺杂、包覆配方以及结构设计等方面都应进行相应的调整。对高镍材料降钴研究工作进行了总结和展望。High-nickel cathode materials have received widespread attention due to their high capacity,environmental friendliness and other excellent comprehensive properties.While pursuing energy density,high nickel cathode materials are accompanied by a decrease in cobalt content.Cobalt has an important influence on the structural stability of the material,as the cobalt content decreases,the intrinsic characteristics of the material and the reaction mechanism will change significantly.Therefore,its synthesis process,doping,coating formula,and structural design should be adjusted accordingly.This article reviews the efforts about the progress in high nickel low cobalt material.
