Macroscopic and 3D superaligned CNT (SACNT) sponges are fabricated through a simple, low‐cost, controllable, and scalable self‐assembly method without using organic binder. Sponges with specific shapes and densities can be achieved. SACNT sponges are ultralight (1–50 mg cm −3 ), highly porous (97.5%–99.9%) with honeycomb‐like hierarchical structure, and highly conductive. Using SACNT sponges as templates, various materials with honeycomb‐like structure can be obtained for wide applications.
