摘要

NiFe2V2O8@NC nanostructures with hierarchically porous yolk-double shell spherical architectures are elaborately fabricated via a facile template-free protocol. Benefited from the expanded ion-transport channels, as well as the activation of synergetic cation-oxygen redox, the electrode manifests excellent rate capability and cycling stability.
