| titleOfInvention | A kind of preparation method of nitrogen-doped, boron-doped or phosphorus-doped graphitized carbon nitride material |
| abstract | A method for preparing a nitrogen-doped, boron-doped or phosphorus-doped graphitized carbon nitride material belongs to the technical field of lithium-sulfur batteries. The invention is to solve the problem of the shuttle effect of lithium-sulfur batteries. After the dicyandiamide is fully ground, it is transferred to a corundum crucible with pores left in the crucible. That is, a nitrogen-doped graphitized carbon nitride material is obtained. The conductive carbon black and PTFE emulsion were mixed uniformly, and deionized water was added to mix uniformly, fully ground for 20 minutes, removed moisture, rolled, punched, and dried, and the prepared conductive composite film was embedded between the sulfur cathode and the separator. The preparation method of the invention is simple and feasible, the prepared composite membrane intercalation has good electrical conductivity, and will not cause negative impact on the sulfur positive electrode, and it is embedded between the sulfur positive electrode and the separator to block polysulfur by physical and chemical adsorption. The shuttle effect of anions, thereby improving the cycling performance of lithium-sulfur batteries. |
