中文摘要	结构式为Li[Ni,Co,Mn]O2的层状镍钴锰三元材料由于具有容量高、结构稳定、安全性好、成本低且对环境没有污染等优点而受到动力电池市场的广泛关注。但是它也存在高温大倍率放电性能及高充电截止电压条件下的循环稳定性能差等缺点。介绍了三种三元材料的合成改性工艺和两种基体改性方法,分别包括离子交换法、超声辅助合成法、熔盐法和表面包覆、掺杂等。并对其未来发展进行了展望。; Because of its high specific capacity, relatively stable structure, good safety performance, low cost and no environment pollution, the layer-type cathode material Li[Ni,Co,Mn]O2 has been paid much attention in the field of power battery. However, there still exist some defects on it, such as poor cycling stability under high cut-off voltage, and poor discharge capacity under high temperature when cycling at high rate. In this paper, three kinds of new synthesis methods and two kinds of ways for modification were mainly introduced, such as ion exchange method, ultrasound assisted synthesis method, molten salt method, surface coating and doping. The developing trend of Li[Ni,Co,Mn]O2 was also prospected.
