NOVELTY - The utility model claims a graphene-based fiber material of soft full-solid-state super capacitor, comprising a flexible substrate, and fixed on the flexible substrate of the anode graphite fibre and a negative graphite fibre, the anode graphite fibre and cathode graphite fibre with same length and diameter are the same; the anode graphite fibre and cathode graphite fibre are arranged in parallel, and has a certain distance between anode graphite fibre and cathode graphite fibre, the space filled by the gel electrolyte. namely, anode graphite fibre and the cathode graphite fibre coated by the gel electrolyte; the anode graphite fibre and cathode graphite fiber are the same, both of them are composed in the middle of polyacrylonitrile fibre and composite of graphene film on the polyacrylonitrile fibre. The utility model claims a electrical conductivity of the super capacitor reaches 4.59 asterisk 103S/m, the specific capacitance is 158mF/cm3 and has good bending flexibility, applied to flexible energy storage device and so on.
