Abstract：Problems of high-nickel ternary materials such as unstable surface structure, lithium-nickel co-segregation, and intergranular cracking led to a decrease in the cycling performance of the materials and inability to fully utilize high specific capacity. Surface coating was the primary approach to address these problems. Currently, coating materials mainly included electrochemically inert materials, ion/electron-conductive materials, and composite coating materials. A review was conducted on the surface modification research of high-nickel ternary materials from these aspects. The mechanisms for interface improvement and stabilization of different types of coating materials, enhancement of ion migration at the solid-liquid interface, suppression of interface side reactions, and their impacts on the electrochemical performance were introduced. The development directions of surface modification of high-nickel ternary cathode materials were also discussed.
