[Epub ahead of print]Amorphous, hydrogenated, and self-ordered nanoporous Nb2 O5 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.© 2016 WILEY-VCH Verlag GmbH & Co.
