| titleOfInvention | A graphene/sulfur/nickel hydroxide self-supporting composite material for positive electrode of lithium-sulfur battery and preparation method thereof |
| abstract | The invention relates to a graphene/sulfur/nickel hydroxide self-supporting composite material for a positive electrode of a lithium-sulfur battery and a preparation method thereof. The material is that the surface of graphene oxide loaded with nano-sulfur particles is covered with nickel hydroxide. The method firstly mixes the sulfur source and graphene oxide evenly to generate graphene gel, then grows nano-sulfur particles on the surface of graphene, and finally covers a layer of nickel hydroxide on the surface of nano-sulfur particles. In the present invention, a layer of nickel hydroxide is covered on the surface of the sulfur-loaded graphene oxide to form a sandwich structure with sulfur as the center, the graphene oxide is used as a current collector, and the covered nickel hydroxide is used as a carrier for limiting the shuttle effect of polysulfides , which can effectively improve the cycle performance of lithium-sulfur batteries. |
