Abstract
The self-supported 3D porous reticular Nb2O5@Carbon (Nb2O5@3D PRS) thin film with interpenetrating network were prepared by a facial electrostatic spray deposition (ESD) technique. The Nb2O5@3D PRS displays outstanding electrochemical performance, especially long cycle life: it can still deliver a specific capacity of 130 mAh g-1 after 7500 times chare/discharge at high rate of 10 C. The excellent sodium storage performance of the Nb2O5@3D PRS is ascribed to the synergistic effect of the unique porous structure, the nanosized Nb2O5 particles encapsulated in the carbonaceous matrix, which facilitates the electrochemical kinetics between the Nb2O5 and electrolyte.152
