title: Graphene-based single fiber supercapacitor with a coaxial structure.
abstract: A novel all graphene coaxial fiber supercapacitor (GCS) was fabricated, consisting of a continuously wet-spun core graphene fiber and facilely dip-coated graphene sheath. GCS is flexible, lightweight and strong, and is also accompanied by a high specific capacitance of 205 mF cm(-2) (182 F g(-1)) and high energy density of 17.5 μW h cm(-2) (15.5 W h kg(-1)). The energy density was further improved to 104 μW h cm(-2), when an organic ion liquid electrolyte was used.
