| titleOfInvention | Flaky Sb for sodium ion battery cathode2Se3Method for preparing nanocrystalline |
| abstract | Sodium ion batteryFlake Sb for cell negative electrode 2 Se 3 The preparation method of the nanocrystalline comprises the steps of adding polyvinylpyrrolidone and tartaric acid into deionized water to obtain a solution A1, and then adding antimony potassium tartrate into the solution A1 to obtain a solution A2; adding sodium selenite into hydrazine hydrate to obtain solution B; dropwise adding the solution B into the solution A2 to obtain a mixed solution C; transferring the mixed solution C to a polytetrafluoroethylene lining, putting the polytetrafluoroethylene lining into a homogeneous phase reactor, reacting at 100-150 ℃, cooling to room temperature along with a furnace, repeatedly washing with deionized water and absolute ethyl alcohol to separate precipitates, and freeze-drying to obtain the flaky Sb for the cathode of the sodium ion battery 2 Se 3 And (4) nanocrystals. The method adopts a one-step hydrothermal method, has simple equipment, is green and safe, has lower reaction temperature and good repeatability, and is suitable for large-scale production; the characteristic that the liquid phase environment is easy to control the appearance structure of the product is utilized, crystal development is induced under the action of polyvinylpyrrolidone and tartaric acid, and the flaky pure phase Sb is successfully prepared 2 Se 3 And (4) nanocrystals. |
