Title:
ROD-SHAPED SODIUM ION POSITIVE ELECTRODE MATERIAL, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/093181
Kind Code:
A1
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(FeaTb)PO4/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
