摘　　要：锂离子电池用三元正极材料LiNixCoyM1-x-yO_2(M为Mn或Al)具有比容量高、成本低等优点,已实现商业化应用。然而三元正极材料在安全性能、循环性能、储存性能、加工性能等方面仍存在不足,很多研究结果表明合理的结构设计是改善三元正极材料性能的有效手段。总结了三元正极材料结构设计的研究进展,并对其未来的应用前景进行了展望。The ternary cathode material LiNixCoyM1-x-yO2 （M=Mn or Al） for lithium-ion batteries had the advantages of high specific capacity and low cost, and had been commercialized. However, there were still some challenges such as safety, cycle, storage and processing pertbrmance. Many research results showed that the reasonable structure design was an effective way to improve the performance of ternary cathode materials. The research progress on the structure design of ternary cathode material was summarized, and the future application prospect was also prospected.
