The invention discloses a high-performance graphene electrode material for a supercapacitor. Graphene, rare earth, titanium tetrachloride, ferric trichloride, methylacetamide and magnesium hydroxide are used as the main components; then N-methylbutyl piperidine bis(trifluoromethylsulfonyl)imide, pentaethylene glycol, methyl triethoxysilane, cocoanut oil, lithium cobalt oxide, methyl anyl alcohol, cyclohexanone, a dispersing agent, a silane coupling agent and an adhesive are added; and processes of ultrasonic dispersion, stirring and banburying, mixing in an inert gas environment, spraying and drying, coating an electrode with a material, and the like are adopted in an auxiliary manner; and therefore, the prepared high-performance graphene electrode material for the supercapacitor has reliable electrical performance, excellent conductivity and high dielectric constant, can satisfy requirements of industries, and has quite bright application prospect. 本发明公开了种超级电容器用高性能石墨烯电极材料，以石墨烯、稀土、四氯化钛、三氯化铁、甲基乙酰胺、氢氧化镁为主要成分，通过
