▎ 摘 要
NOVELTY - Graphene/oxide based electrode material comprises nano-ferric oxide, graphene porous macromolecule and nano-sulfur. The preparation of graphene/oxide based electrode material comprises adding ferric chloride solution to graphene oxide hydrosol, stirring for 1-3 hours, adding ammonia water and adjusting pH to 9-11; dropping hydrazine hydrate solution and stirring for 0.5-3 hours; heating at 130-190 degrees C for 3-10 hours and removing aqueous phase, then solvent; and mixing with nano-sulfur powder and reacting under argon atmosphere at 130-180 degrees C for 9-15 hours. USE - Graphene/oxide based electrode material used for preparing lithium-sulfur battery (claimed). ADVANTAGE - The electrode material has strong chemical bond, limits sulfur dissolution, reduces shuttle effect and improves battery reaction kinetic activity, active substance utilization rate, specific capacity and cycle stability.
