As a new type of green energy,lithium-ion battery has shown great potential to replace traditional petrochemical energy inmany fields,and has made remarkable contributions to the practice of green sustainable development and the reduction of carbonemissions. As an important part of lithium-ion batteries,and their performance determines the future development space of lithium-ionbatteries. At this stage,the cathode materials of lithium-ion batteries are relatively mature and stable,while the cathode materials oflithium-ion batteries are diverse,with many controllable factors and huge development space,which is the most critical unit for the rapiddevelopment of lithium-ion batteries. Nickel-cobalt-manganese ternary cathode material has the advantages of high energy density,environmental friendliness and reversible capacity,and is considered as one of the most potential cathode materials at present and in thefuture. In recent years,Ni−Co−Mn ternary cathode materials have shown strong commercial potential. At the same time,people have putforward higher requirements for Ni−Co−Mn ternary cathode materials. Due to the essential problem of poor cycle stability of cathodematerials,there is a big difference between their actual performance and theoretical performance. Due to their rich controllability,there isa huge room for improving the performance of Ni−Co−Mn ternary cathode materials. In this work,the problems existing in Ni−Co−Mnternary cathode materials were mainly discussed,including mixed discharge of Ni/Li,residual alkali on the surface,release of activeoxygen,dissolution of transition metal ions and intergranular crack,and the effects and mechanisms of performance enhancementstrategies such as element doping,surface coating and synergistic effect of element doping and surface coating on the properties ofNi−Co−Mn ternary cathode materials were expounded,so as to provide new research ideas for researchers in this field,stimulate more innovative ideas and promote the rapid development of Ni−Co−Mn ternary cathode materials.
