The present disclosure discloses a preparation method of a Ni-Rich ternary precursor and use thereof. The preparation method includes the following steps: under specified conditions, feeding an alkali liquor and a metal salt solution simultaneously for a precipitation reaction to obtain particles with D50 of 7.0 μm to 15.0 μm; continuously feeding a seed crystal, and after D10 of the particles is adjusted to 2.0 μm to 7.0 μm, stopping feeding the seed crystal; continuously feeding the alkali liquor and the metal salt solution, and collecting an overflow material; and when a particle size grows to D50 of 7.0 μm to 15.0 μm once again, repeating the above operation of adding a seed crystal, and continuously collecting an overflow material; and washing, drying, and sieving the collected materials to obtain the Ni-Rich ternary precursor.
