It is urgent to solve the problems of the dramatic volume expansion and pulverization of SnO 2 anodes during cycling process in battery systems. To address this issue, we design a hybrid structure of N-doped carbon fibers@SnO 2 nanoflowers (NC@SnO 2 ) to overcome it in this work. The hybrid NC@SnO 2 is synthesized through the hydrothermal growth of SnO 2 nanoflowers on the surface of N-doped carbon fibers obtained by electrospinning. The NC is introduced not only to provide a support framework in guiding the growth of the SnO 2 nanoflowers and prevent the flower-like structures from agglomeration, but also serve as a conductive network to accelerate electronic transmission along one-dimensional structure effectively. When the hybrid NC@SnO 2 was served as anode, it exhibits a high discharge capacity of 750 mAh g −1 at 1 A g −1 after 100 cycles in Li-ion battery and 270 mAh g −1 at 100 mA g −1 for 100 cycles in Na-ion battery, respectively.
