| titleOfInvention | A cross-linked porous polymer lithium-sulfur battery cathode carrier material containing maleimide structure, preparation method and application thereof |
| abstract | A cross-linked porous polymer lithium-sulfur battery positive electrode carrier material containing a maleimide structure, a preparation method and an application thereof, belong to the technical field of organic lithium-sulfur battery electrode materials. The present invention prepares porous positive electrode support material by using multifunctional maleimide monomer to carry out high-temperature cross-linking free radical polymerization in a high-capacity reactor to increase yield, and diphenyl sulfone can be recycled as a reaction solvent to reduce Production cost; the prepared porous cathode support material can restrict the diffusion of polysulfides through the large amount of nitrogen, oxygen heteroatoms and micropores and mesopores contained therein, thereby suppressing the shuttle effect and achieving excellent electrochemical performance. The maleimide-containing cross-linked porous polymer of the present invention can be used as a positive electrode carrier material in a lithium-sulfur battery, and can significantly improve the cycle stability of the battery, so that the battery can still maintain energy after a long cycle. Maintain high capacity and coulombic efficiency. |
