Ultraflexible In-Plane Micro-Supercapacitors by Direct Printing of Solution-Processable Electrochemically Exfoliated Graphene

A novel direct printing approach for fabrication of in‐plane micro‐supercapacitors (MSCs) is demonstrated. Solution‐processed graphene/conductive‐polymer hybrid inks are utilized. The fabricated MSCs on paper substrates offer significant areal capacitance and excellent rate capability. An ultrathin...

Description
Summary:A novel direct printing approach for fabrication of in‐plane micro‐supercapacitors (MSCs) is demonstrated. Solution‐processed graphene/conductive‐polymer hybrid inks are utilized. The fabricated MSCs on paper substrates offer significant areal capacitance and excellent rate capability. An ultrathin MSC on a poly(ethylene terephthalate) (PET) substrate (2.5 μm thick) exhibits “ultraflexiblity,” making it suitable for next‐generation flexible microelectrochemical energy‐storage devices.
