Three-dimensional aerogels assembled by interconnected 1D and 2D nanostructures building blocks have been anticipated as a prospective candidate for advanced energy storage and conversion materials. Herein, we present a simple scalable strategy for fabricating a free-standing flexible nitrogen-doped carbon nanotubes reinforced graphene (N-DC/G) aerogel via chemical oxidative polymerization facilitated by self-assembly soft-template of lithocholic acid, followed by high-temperature pyrolysis carbonization in an Ar atmosphere. The 3D interconnected macroporous structure of the resulting aerogel provides fast transport of electrons and electrolyte ions, while the hollow nitrogen-doped carbon nanotubes and graphene nanosheets provide both strong support for the aerogel and mechanical flexibility. The resulting N-DC/G electrode has a remarkable initial discharge capacity of 734.21 mAh g(-1) at a current density of 200 mA g(-1), exceptional cycling stability (663.34 mAh g(-1) following 400 cycles), and an outstanding rate performance as an anodic material in Li-ion batteries. The outstanding lithium storage properties of N-DC/G aerogels are due to their electrically conductive 3D framework and the associated porous channels, which allow for an efficient electrolyte ion diffusion, and rapid electron transport, while preserving the stability of the structure.
