Partially single-crystalline mesoporous Nb2 O5 nanosheets with orthorhombic structure in between graphene are scalably fabricated via a simple nanocasting method. The well-designed architecture provides numerous open and short channels for fast diffusion of sodium ion and good electronic conductivity, resulting in an enhanced electrochemical performance and a favorable high-rate behavior for sodium storage.
