Abstract

The rapid development of wearable electronics has increasingly demanded high-performance flexible power-supply devices for enhancing portability and durability. Flexible solid-state supercapacitors (FSSSCs) could have potential to fulfill this demand, but engineering electrode materials is still a challenging issue. Herein, we demonstrate optimal structuring nitrogen-doped hybrid-dimensional nanocarbons (N-RGO-CNT-CBNP) for high-performance FSSSCs. Three types of representative nanocarbons including reduced graphene oxide nanosheets, carbon nanotubes and carbon black nanoparticles are explored as building blocks to construct N-RGO-CNT-CBNP synergistically via facile and low-cost solution processing. With melamine as both a structure-directing agent and a highly effective nitrogen source, a highly-porous threedimensional hierarchical structure and a high nitrogen doping level of 13.8 at.% are simultaneously achieved. Such a nanostructured material is employed to fabricate sandwich-structured papers (N-RGO-CNT-CBNP-Ps) with high flexibility, conductivity and mechanical strength. The resulting N-RGO-CNT-CBNP-Ps possess an ultrahigh areal specific capacitance (935 mF cm-2 at 1 mA cm-2), as well as remarkable rate capability (e.g. 580 mF cm-2 at 100 mA cm-2) and cyclic stability (e.g. 91.6% retention after even 40,000 cycles at 50 mA cm-2). An N-RGO-CNT-CBNP-P based FSSSC displays both high energy density and power density, while satisfying operational reliability/durability requirements. The results indicate that the NRGO-CNT-CBNP-P based FSSSCs hold promise towards their practical applications for wearable electronics.
