Abstract: 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.

Key words: LiNi0.8Co0.15Al0.05O2, cathode materials, surface coating, ion doping, lithium ion batteries
