A positive electrode material, and a preparation method therefor and the use thereof. The preparation method comprises the following steps: (1) mixing a vanadium source, a complexing agent and a high-molecular polymer with an organic solvent to obtain a mixed solution; (2) respectively performing an atomization treatment on the mixed solution and a metal salt solution, and respectively conveying the mixed solution and the metal salt solution with a gas into a spray pyrolysis furnace to perform mixed pyrolysis, so as to obtain a coated precursor; and (3) mixing the coated precursor with a lithium source or a sodium source, and sintering same to obtain a positive electrode material. By using a spray pyrolysis method, the tap density and uniformity of the precursor are improved while the precursor is coated, such that a positive electrode material having good performance can be prepared.
