摘要：

Constructing 3D carbon structures built from carbon nanotubes (CNTs) and graphene has been considered as an effective approach to achieve superior properties in energy conversion and storage because of the synergistic combination of the advantages of each building block. Herein, a facile solid-state growth strategy is reported for the first time to fabricate highly nitrogen doped CNT-graphene 3D nanostructures without the necessity to use chemical vapor deposition. As cathode hosts for lithium-sulfur batteries, the hybrid architectures exhibit reversible capacities of 1314 and 922 mAh g(-1) at 0.2 and 1 C, respectively, and a capacity retention of 97% after 200 cycles at a high rate of 2 C, revealing their great potential for energy storage application.
