Abstract | The nanostructures of electrodes are performance determining factors in energy storage devices. However, the development of a hierarchical architecture, which can provide high specific capacity and long cycling stability, is a bottleneck. Herein, we have developed two different nanostructures of Nb2O5, namely, nanoscrolls and nanosheets, and compared their electrochemical properties as anodes for Li-ion batteries. It was revealed that the Nb2O5 nanostructure significantly affects the battery performance in terms of rate performance and cycling stability. The Nb2O5 nanoscrolls delivered a relatively superior reversible capacity (438 mA h g–1) with 85% capacity retention after 5000 charge–discharge cycles. This investigation evidenced that the electrode nanostructure plays a significant role in its electrochemical performance. |
