    Abstract: Provided are ternary positive electrode material precursor and preparation method thereof, ternary positive electrode material, lithium-ion battery, positive electrode, and electric-involved equipment. The precursor includes, sequentially from inside to outside, core layer, first intermediate layer, second intermediate layer, and shell layer. Porosities of core layer, first intermediate layer, and second intermediate layer increase sequentially. Shell layer has the smallest porosity or no porosity. The method includes: performing first reaction of raw materials including nickel-cobalt-manganese ternary metal salt mixed solution, complexing agent, and pH modifier to obtain core layer; performing second reaction to form first intermediate layer on surface of core layer; performing third reaction to form second intermediate layer on surface of first intermediate layer; and performing fourth reaction to form shell layer on surface of second intermediate layer.
