Research on Fe2O3@C nanofiber as an anode material for sodium ion batteries
One-dimensional Fe2O3@C composite nanofibers were synthesized by electrospinning,and the electrochemi-cal properties of the nanofibers were explored.XRD results show that the nanofibers belong to the cubic crystal system with P4132(213)space group.SEM results confirm that the morphology is fibrous,and the diameter of the fiber is about 100～200 nm.The sodium-ion battery assembled with this material has a charge specific capacity of 317.8 mAh·g-1 for the first time and 168.8 mAh·g-1 after 100 cycles of current density.
