Amorphous, hydrogenated, and self‐ordered nanoporous Nb 2 O 5 films serve as an excellent binder‐free electrode for sodium batteries, affording a high and sustainable capacity delivery and robust high‐rate capability. This collaborative material engineering of structural order (amorphization), composition (hydrogenation), and architecture (ordered nanopore) opens up new possibilities to develop an energy storage solution that is more accessible, sustainable, and producible.
