| titleOfInvention | Preparation method of carbon fiber/sulfur composite positive material with multilevel structure |
| abstract | The invention relates to a preparation method of a carbon fiber/sulfur composite positive material with a multilevel structure and belongs to the technical field of chemical engineering electrode material preparation processes. The preparation method comprises the steps of preparing a carbon fiber by an electrostatic spinning method, adding metal salt into a spinning solution, calcining in an inert atmosphere, catalyzing graphitization of the carbon fiber by virtue of a metal formed in situ on one hand, removing metal particles to form hollow carbon spheres by virtue of the metal formed in situ on the other hand, and then adsorbing sulfur into the graphitized hollow carbon spheres by virtue of a gas-phase thermal evaporation method. With the adoption of the carbon fiber/sulfur composite positive material with the multilevel structure, the rate capability of the material is greatly improved, the dissolution of polysulfide is also inhibited, and the cycle performance and the coulombic efficiency of the material are improved. The preparation method is simple and easy, is high in controllability of technological parameters and low in energy consumption and has a low equipment requirement. |
