Abstract
The present invention relates to the technical field of lithium ion positive electrode materials, and discloses a ternary positive electrode material precursor and a preparation method thereof. The ternary positive electrode material precursor prepared by the present invention is prepared by using three elements of nickel, cobalt and manganese to prepare a core layer precursor, and then using an anionic surfactant to modify it, using electrostatic adsorption to adsorb a positively charged modified hyperbranched polyester on the surface of the surface modified precursor, and using molybdenum acetate and magnesium acetate as molybdenum sources and magnesium sources for element doping to obtain the ternary positive electrode material precursor. The ternary positive electrode material precursor has excellent cycle stability, safety and electrochemical performance.
