Nitrogen-doped aligned CNT/graphene sandwiches are rationally designed and in-situ fabricated by a facile catalytic growth on bifunctional natural catalysts that exhibit high-rate performances as scaffolds for lithium–sulfur batteries, with high initial capacity of 1152 mAh g-1 at 1.0 C. A remarkable 770 mA h can be achieved 5.0 Such design strategy materials opens up new perspectives to novel advanced functional composites, especially interface-modified hierarchical nanocarbons broad applications.
