| titleOfInvention | Preparation method of nano nickel-cobalt-sulfur particles used as lithium-sulfur battery positive electrode |
| abstract | The invention relates to a preparation method of nano nickel-cobalt-sulfur particles used as a positive electrode of a lithium-sulfur battery, which comprises the following steps: dissolving cobalt nitrate hexahydrate, nickel nitrate hexahydrate and sodium acetate in a solvent, adding potassium persulfate or ammonium persulfate, stirring, pouring into a reaction kettle for reaction, cooling, washing, centrifuging, drying, dissolving in the solvent, ultrasonically treating, adding sodium sulfide nonahydrate, pouring into the reaction kettle for reaction, cooling, washing, centrifuging and drying to obtain the catalyst. The method is simple and easy to implement, safe and environment-friendly, has easily available raw materials and low cost, and is suitable for large-scale production; the prepared nano nickel-cobalt-sulfur particles are small in size, the specific surface area is increased, the nano nickel-cobalt-sulfur particles have a good fixing effect on polysulfide, and the shuttle effect of the battery is obviously weakened. In addition, nickel cobalt sulfide has good conductivity compared with oxides and binary sulfides which are generally used for sulfur fixation. The cycling stability of the battery is improved under the condition of ensuring a certain specific capacity, and the lithium-sulfur battery has great potential on the aspect of solving the existing problems of the lithium-sulfur battery. |
