| titleOfInvention | Sodium cobalt pyrophosphate/carbon composite cathode material, preparation and application thereof |
| abstract | The invention discloses a sodium cobalt pyrophosphate/carbon composite cathode material, wherein the general chemical formula of the sodium cobalt pyrophosphate is Na 2‑ 2x Co 1+x P 2 O 7 Wherein x is more than 0 and less than or equal to 0.25. The invention also discloses a preparation method of the composite cathode material, which comprises the steps of dissolving a cobalt source, a sodium source and a phosphorus source in water according to the element proportion of the chemical formula to obtain a mixed solution, adding a complexing agent into the mixed solution, stirring and heating to obtain gel, and drying the gel to obtain a precursor; and calcining the precursor to obtain the composite cathode material. In addition, the invention also provides application of the composite cathode material as a cathode material of a sodium-ion battery. The preparation method is simple and has mild conditions. The prepared positive electrode material of the sodium ion battery has uniform granularity and good appearance, is used for the sodium ion battery, has high specific capacity and high voltage, and shows good circulation stability. |
