In the novel coronavirus epidemic, Russia–Ukrainian war environment, oil, and other energy resources are in short supply. With the increase of oil prices, electric vehicles become mainstream vehicles. As the core component of electric vehicles, batteries have become an integral part of people's daily life. The development of high‐performance, pollution‐free batteries has become the focus of the world. Because of the advantages of high specific capacity, environmental friendliness and low cost, ternary cathode material have become a research hotspot of lithium‐ion batteries. This paper mainly selects high nickel ternary material as the research object, and from its working principle, composition structure, material preparation, reaction mechanism, existing problems, and modification method to six aspects of a more comprehensive overview, for future researchers to provide a beneficial reference.
