Abstract
In this work, a novel porous amorphous Fe2O3/nitrogen-doped carbon composite as a promising anode material for sodium-ion batteries has been fabricated by in situ growing amorphous Fe2O3 on 3D interconnected nitrogen-doped carbon nanofibers. The as-prepared composite exhibits superior sodium storage properties. It delivers a high reversible capacity of 408 mA h g−1 after 350 cycles at a current density of 100 mA g−1 and a good rate capability of 183 mA h g−1 at 3 A g−1. The excellent electrochemical performance is owing to the synergistic effects of the amorphous structure of Fe2O3 and the 3D interconnected nitrogen-doped carbon network with high nitrogen doping content (10 atom%), which do not only relieve the internal stress of the electrode and accommodate more electrochemical active sites for Na+ storage, but also buffer the volume changes of amorphous Fe2O3 as well as facilitate the electronic and ionic transportation during cycling.
