Layered structural LiNi1/3Co1/3Mn1/3O2 is one of the most promising materials used as a cathode for Li-ion battery in electric vehicles, mainly due to the high capacity, the stable structure, the thermal stability and the low cost of LiNi1/3Co1/3Mn1/3O2. In this review, the structure, the electrochemical performances and the methods for improving its electrochemical performances of LiNi1/3Co1/3Mn1/3O2, such as doping with other ions, coating with other materials and the preparation of special structural nanomaterials, are included. In recent years, the researchers on Li-ion battery are concerned with various nanomaterials. The electrochemical performances of materials are closely related with the size, the morphology, the porosity, the crystalline features and the specific surface area of the material. Therefore, these effects should be considered for improving the electrochemical performances of LiNi1/3Co1/3Mn1/3O2 cathodes.
