| description | The invention relates to a coated high-nickel ternary precursor and a preparation method thereof. The chemical formula of the coated high-nickel ternary precursor is as follows: NixCoyMnz (OH) 2 MO.(OH) 2, wherein x + y + z = 1, x is more than or equal to 0.8 and less than 1, y is more than 0 and less than or equal to 0.2, and z is more than 0 and less than or equal to 0.2; M is selected from at least one of Zr, Ti and V. The coated high-nickel ternary precursor is uniformly coated with the required elements on the surface of the high-nickel ternary precursor by a liquid-phase ion exchange method. According to the coated high-nickel ternary precursor prepared by the invention, elements can be uniformly coated on the surface of particles, the coating amount can be accurately controlled through the addition amount of M salt, the coated high-nickel ternary precursor is used as a raw material to be uniformly mixed with lithium hydroxide, and the high-nickel ternary lithium ion battery anode material is prepared b |
