Abstract

Reduced graphene oxide (rGO) loaded Fe-Fe3C composite nanofibers were prepared via a supersonic blowing technique. After high temperature annealing, the resulting electrodes delivered an excellent reversible capacity of 558 mAh·g−1 at a current rate of 1500 mA g−1 at the 200th cycle. The supersonic blowing facilitated rapid and simultaneous coupling of exfoliated rGO with the solution-blown nanofibers, which is difficult to achieve by electrospinning methods. The performance of the fabricated electrode is remarkably high compared to the previously reported values; thus, these anodes are promising for application in lithium ion batteries.
