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 a high initial capacity of 1152 mAh g ‐1 at 1.0 C. A remarkable capacity of 770 mA h g ‐1 can be achieved at 5.0 C. Such a design strategy for materials opens up new perspectives to novel advanced functional composites, especially interface‐modified hierarchical nanocarbons for broad applications.
