Nickel-rich ternary cathode materials are the preferred cathode materials for large power lithium ion batteries due to their high capacity and high power. However, high nickel ternary cathode materials have some disadvantages, such as poor cyclic stability and fast capacity fading. It is indicated that cationic mixing, precipitation of transition metal element, oxygen vacancy, etc. are direct factors causing the material phase transformation, while interfacial film, overcharge, microcrack, etc. can further accelerate the material capacity fading. The existing modification technologies, such as element doping, surface coating and material composite, can inhibit the capacity fading of materials. In this review, the capacity fading mechanism and modification methods of high nickel ternary materials in recent years were represented, and a outlook for its future development was prospected.
