NOVELTY - A super capacitor based on graphene-carbon nano tube composite material, relating to a super capacitor device . Is to solve the problem of the graphene thin film based on-a carbon nano tube composite electrode of super capacitor is carbon nano tube is easy to break the root, dynamic performance is bad problem is. The device comprises a super capacitor unit, the second super capacitor unit and shell, a super capacitor unit comprises the collector A, collecting electrode C, graphene-carbon nano tube composite material and a diaphragm A, the second super capacitor unit comprises the collector B, collecting electrode C, graphene-carbon nano tube composite material and a diaphragm B, a super capacitor unit and the second capacitor unit common super-collecting electrode C, the graphene-carbon nano tube composite material comprising a substrate and comb teeth, a comb base is integrated structure. This utility new type not only enhance the dynamic performance of a, but also increase a capacity of a charge. For a field.
