| description | The invention relates to a polyanionic sodium-ion battery positive electrode material, a preparation method thereof and a battery. The method comprises the following steps: mixing precursor powder of the positive electrode material of the polyanionic sodium-ion battery with a fluorine-containing carbon source by adopting a set mixing mode to obtain semi-finished product powder; calcining the semi-finished product powder under the protection of a protective atmosphere by adopting a set calcining mode to obtain a calcined product; and obtaining the fluorocarbon-based carbon-coated polyanion type sodium ion battery positive electrode material according to the calcined product. According to the scheme provided by the invention, the fluorocarbon-based carbon-coated polyanion type sodium ion battery positive electrode material can be obtained, and the discharge platform voltage and the discharge specific capacity of the polyanion type sodium ion battery can be improved.
