摘要：
Amorphous, hydrogenated, and self-ordered nanoporous Nb2O5 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 nano-pore) opens up new possibilities to develop an energy storage solution that is more accessible, sustainable, and producible.
