▎ 摘　　要

NOVELTY - The core-sheath flexible graphene fiber super capacitor has a graphene fiber core layer. A polymer electrolyte intermediate layer are mounted around the core layer. A graphene fiber sheath is mounted around the intermediate layer. The first liquid flow is distributed around the second liquid flow. The second liquid flow is distributed around the third liquid flow. The spinning solution is configured to graphene oxide uniformly dispersed and a reducing agent. USE - Core-sheath flexible graphene fiber super capacitor. ADVANTAGE - The core-sheath flexible graphene fiber super capacitor has high specific capacitance and energy density, good flexibility, can be woven, and is easy to be enlarged, and can be widely used in energy storage, flexible materials and other fields. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a preparation method; and (2) a preparation system. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a preparation process of a core sheath type flexible graphene fiber supercapacitor. (Drawing includes non-English language text)
