NOVELTY - This utility model claims a kind of super-capacitor composite electrode, comprising a nickel net or copper net, Co3S4 nano ball thin film layer and a three-dimensional graphene oxide intermediate layer between the base layer and an outer layer. The super-capacitor composite electrode as a nickel net or a net, using chemical vapour deposition method to grow the three-dimensional graphene layer on the substrate layer, and a hydro-thermal method on the three-dimensional graphene layer is Co3S4 nano ball thin film layer. Sandwich structure of this utility model is a composite electrode that is base layer/three-dimensional graphene oxide/sulfide is a very stable excellent structure, the electrode capacitance is much higher than normal of the capacitor.
