Abstract

Abstract : Solid‐state supercapacitors and micro­supercapacitors are fabricated from a pristine graphene ink by solution casting and inkjet printing. The devices exhibit high performance, with a volumetric device capacitance up to 17.8 F cm −3 . With a simple fabrication process and robust tolerance to mechanical deformation, this work represents a promising technology for low‐cost, portable, and flexible energy storage.
