Disclosed are a ternary single crystal positive electrode material, a preparation method therefor and use thereof. The preparation method comprises the following steps: mixing a ternary polycrystalline micropowder, raising a temperature, carrying out a primary sintering, and lowering the temperature to obtain an intermediate; subjecting the intermediate to jet pulverization to obtain a single crystal material, washing the single crystal material with water, and centrifugally drying the single crystal material to obtain a material with a residual alkali content of less than 1500 ppm; and adding a coating agent to the material, raising a temperature, carrying out a secondary sintering, and lowering the temperature to obtain the ternary single crystal positive electrode material. In the present disclosure, by using a jet pulverization device to open a polycrystalline material to form small single crystal particles, the electrochemical performance and the energy density of the material is improved.
