The present invention relates to the technical field of battery materials. Disclosed are a doped sodium ferric phosphate positive electrode material, a preparation method therefor and an application thereof. The chemical formula of the positive electrode material is xAlF3-MPO4, wherein M is NaNiaCobFe, 0≤x≤0.2, 0≤a≤1, and 0≤b≤0.5. In the doped sodium ferric phosphate positive electrode material prepared by the present invention, nickel and cobalt are introduced for doping sodium ferric phosphate, phase transformation in a sodium ion deintercalation process can be improved by adjusting the proportion of nickel and cobalt phosphate, and the effect of improving the cycling stability of a sodium ferric phosphate crystal structure is achieved. Aluminum fluoride is coated on the surface of the doped sodium ferric phosphate, thereby reducing surface loss of sodium ion deintercalation during charging and discharging, improving the cycling stability of the surface of the sodium ferric phosphate, improving resistance of surface reduced iron-based phosphate, and enhancing electrochemical performance of the sodium ferric phosphate.
