By facile electrospinning and subsequent melamine-derived chemical vapour deposition strategy, a three-dimensional (3D) hierarchical binder-free carbon electrode is fabricated via in-situ growing nitrogen-rich graphitic nanotubes on carbon nanofibres. This electrode shows a 3D hierarchical nanostructure with the high specific surface. Owing to the highly conductive hierarchical structure allowing for rapid transportation of electrons and the N-doped carbon creating more Li-storage sites, the as-prepared binder-free electrode exhibits high reversible capacity, good rate capability and long cycle stability in terms of Li-ion battery.
