Quasi-solid-state micro-supercapacitors with cellular graphene film as the active material and polyvinyl alcohol/H3PO4as the gel electrolyte have been fabricated. The 3D porous graphene films not only serve as high performance supercapacitor electrodes, but also provide an abundant ion reservoir for the gel electrolyte.
