Nickel-rich ternary materials for lithium ion batteries are the preferred cathode materials for automotive power batteries at present and in the future, due to their low cost, high energy density, high reversible capacity and environmental friendliness. On the basis of reviewing the crystal structure and electrochemical properties of nickel-rich ternary materials, the main preparation methods at home and abroad, modification methods such as doping, coating and others were introduced. Meanwhile,
more » ... the effect of different kinds of coating materials on rate performance, cycling performance and good thermal stability of nickel-rich ternary was discussed in details. Finally, the issues about nickel-rich ternary electrolyte solution, safety, compaction density and cycle life were analyzed and prospected.
