▎ 摘  要

NOVELTY - Modified high-nickel ternary material comprises nickel-rich lithium nickel manganese oxide (NCM811) material and lithium fluoride (LiF) and carbon (C) coated on the surface of the NCM811 material. USE - The material is useful as anode material for lithium-ion battery (claimed). ADVANTAGE - The material reduces the dissolution of transition metals, improves the structural stability of the material properties, enhances the cycle stability of the material, enhances the ionic conductivity and electronic conductivity of the material, and improves the electrochemical performance of the NCM811 material. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: Preparation method of modified high-nickel ternary material. Lithium-ion battery anode material, comprising the modified high-nickel ternary material or the modified high-nickel ternary material.
