Layered LiNi1/3Co1/3Mn1/3O2, owing to its excellent electrochemical properties, has been used as cathode material for lithium-ion batteries, especially for hybrid electric vehicles. It has many merits such as high capacity, long cycle life, low cost and little harm to environment. Therefore, LiNi1/3Co1/3Mn1/3O2 has become a great concern by scholars on energy and material fields. However, the electronic conductivity and the charge-discharge capacity at high current should be enhanced before any materials modifications. Here, this paper summarizes the main synthetic technologies of LiNi1/3Co1/3Mn1/3O2 in recent years, including synthesis methods, doping, surface coating modification, and the future development trends discussed.
