| titleOfInvention | Lithium-sulfur battery positive electrode material, preparation method thereof, positive plate and lithium-sulfur battery |
| abstract | A lithium-sulfur battery positive electrode material comprising graphene, a metal sulfide including at least two transition metal sulfides, and sulfur particles that are co-supported on the surface of the graphene. The invention also provides a method for preparing the lithium-sulfur battery positive electrode material, and a positive electrode sheet and a lithium-sulfur battery comprising the lithium-sulfur battery positive electrode material. The lithium-sulfur battery positive electrode material provided by the invention has a structure that at least two metal sulfides are tightly embedded on the surface of graphene to form a conductive network structure, so that a channel is provided for rapid transmission of electrons and ions, and the conversion of polysulfide into over-sulfide lithium and lithium sulfide in the reaction process of the lithium-sulfur battery positive electrode is promoted by utilizing the polar characteristic and the characteristic that the edge of the metal sulfide is rich in active sites, so that the utilization rate of active substances in the lithium-sulfur battery is improved, and the practicability of the lithium-sulfur battery is finally promoted. |
