ResumoA 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.
