Abstract

Disclosed are a rod-shaped sodium ion positive electrode material, a preparation method therefor and an application thereof. The material comprises a rod-shaped base material and nanofibers inserted into the base material. C—Na is loaded on the nanofibers. The chemical general formula of the rod-shaped sodium ion positive electrode material is Na(FeT)PO/CNF-c(C—Na), and 0.001≤c≤0.1, wherein T is at least one of Ni, Co, Zn, Mn, Fe, V, Ti or Mo, 0.9≤a<1, 0<b≤0.2, and 0.001≤c≤0.1. In the present invention, on one hand, some transition metal elements are doped to improve the electrochemical performance thereof, and on the other hand, a modulator is added to synthesize the rod-shaped sodium ion positive electrode material, and the C—Na loaded nanofibers are added to adjust the proportion of large and small rod-shaped materials, so that the composition of a single Na(FeT)POrod-shaped nanostructure is optimized.
