Functionalized Graphene Hydrogel-Based High-Performance Supercapacitors

Functionalized graphene hydrogels are prepared by a one‐step low‐temperature reduction process and exhibit ultrahigh specific capacitances and excellent cycling stability in the aqueous electrolyte. Flexible solid‐state supercapacitors based on functionalized graphene hydrogels are demonstrated with...

Description
Summary:Functionalized graphene hydrogels are prepared by a one‐step low‐temperature reduction process and exhibit ultrahigh specific capacitances and excellent cycling stability in the aqueous electrolyte. Flexible solid‐state supercapacitors based on functionalized graphene hydrogels are demonstrated with superior capacitive performances and extraordinary mechanical flexibility.
