| titleOfInvention | Coated high-nickel ternary precursor and preparation method thereof |
| abstract | 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: ni x Co y Mn z (OH) 2 ·MO(OH) 2 Wherein x + y + z is 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 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 M salt is taken as a raw material to be uniformly mixed with lithium hydroxide, and the high-nickel ternary lithium ion battery anode material is prepared by sintering in an oxygen atmosphere, so that the stability and the cycle performance of the anode material are remarkably improved. |
