摘要
镍钴铝酸锂（LiNi0.8Co0.15Al0.05O2,NCA）因具有高能量密度、高性价比等优点,被视为最具发展潜力的动力锂电池正极材料.但NCA在使用过程中安全性、循环稳定性、高温性能较差,需要通过离子掺杂、表面包覆等方式改性,以改善材料的电化学性能.本工作对NCA的改性研究进行总结,并展望了未来的研究方向.
LiNi0.8Co0.15Al0.05O2 has been regarded as the most promising cathode material for power lithium battery because of its high energy density and high cost efficient. However, some issues, such as safety performance, cyclic stability and high temperature performance, hindered its commercial application. The common ideas to enhance these properties including ion doping and surface coating. The modification of LiNi0.8Co0.15Al0.05O2 cathode materials is summarized in this paper, and also has prospect to the future research orientation.
