  "textContent": "A vanadium sodium phosphate positive electrode material, a sodium ion battery, and a preparation method therefor and application thereof. The preparation method of the vanadium sodium phosphate positive electrode material comprises the following steps: (1) reacting an aqueous solution containing a vanadium source with a phosphorus source, a reducing agent, a sodium source, and a carbon source, the reaction comprising first performing a reaction of an aqueous solution of the vanadium source and the phosphorus source, and then perform a reaction with the reducing agent, or first performing a reaction of the aqueous solution of the vanadium source with the reducing agent and then performing a reaction with the phosphorus source; (2) drying and calcining the reaction liquid obtained in step (1). The vanadium sodium phosphate positive electrode material has a high dispersibility, and has stable circulation performance when used in a battery.",
