The present invention belongs to the technical field of nanometer materials and electrochemistry, and in particular relates to a three-dimensional Na3V2(PO4)3 nanowire network electrode material, a preparation method therefor and a use thereof. The nanowire electrode material has a diameter of 20-60 nm, and a uniform morphology. Nanowires are mutually interleaved to form a three-dimensional network structure, and the structure is stable. In the present invention, the three-dimensional Na3V2(PO4)3 nanowire network electrode material is prepared mainly by a simple and easy-to-employ hydrothermal method combined with a solid-phase sintering method, and exhibits the characteristics of high power and a good cycle stability when used as a positive electrode active material of a sodium ion battery. Secondly, the process of the present invention is simple, a three-dimensional Na3V2(PO4)3 nanowire precursor can be obtained by the simple and easy-to-employ hydrothermal method, and the three-dimensional ...
