摘　　要：总结镍钴铝酸锂高镍系锂离子电池正极材料存在的问题,如循环稳定性不佳、热稳定性差和储存性能差等;综述近年来对容量衰减机理的研究,重点介绍几种改性方法,如优化合成工艺、离子掺杂、表相改性和制备复合材料等;展望镍钴铝酸锂高镍系层状正极材料的发展方向。The problems of Li（Ni,Co,Al） O2high-nickel cathode materials for Li-ion battery were summarized,such as unstable cycle stability,poor thermal stability and poor storage performance. Recent researches on the mechanisms of capacity fading were reviewed. Several modification methods were described,such as improving the preparation process,ion-doping,surface modification and fabrication of composites. The development direction of Li（Ni,Co,Al） O2high-nickel layer cathode materials was prospected.
