Large-Scale Fabrication of BCN Nanotube Architecture Entangled on Three Dimensional Carbon Skeleton for Energy Storage

Abstract

Boron and nitrogen co-doped graphene (BCN) nanotubes have tremendous properties for the energy storage devices. Herein we firstly reported a BCN nanotubes architecture entangled on three dimensional (3D) melamine foam derived carbon skeleton with the high surface area, hierarchical porosity and heteroatoms (B, C, N) extant. Having such efficacious properties, 3D-BCN-950 (calcinated under 950 °C) exhibited excellent capacitance of 344 Fg-1 at current density of 1 Ag-1. Besides, 3D-BCN-950 nanotubes are further utilized as electrodes in symmetric and negative electrode in asymmetric hybrid supercapacitors. The symmetric supercapacitor presented high energy density of 19.8 Whkg-1 and elevated power density of 5074 Wkg-1, the asymmetric supercapacitor also demonstrate the high energy density of 72 Whkg-1 and power density of 22732 Wkg-1. These results indicate the as-synthesized heteroatoms doped graphene nanotubes architecture could be a potential negative electrode materials for the fabrication of future high energy density hybrid supercapacitors.
