Abstract

In this paper, a new composite with Fe3O4 and Cu nanoparticles encapsulated in carbon nanofibers (CNFs) and its electrochemical properties were reported. The composite is fabricated by a simple electrospinning technique followed by heat treatment. At a current density of 100 mA g-1, this electrode exhibits a high reversible capacity of 540.5 mAh g-1 after 100 cycles. Moreover, this composite electrode also shows good rate capability when current density increased from 0.1 to 5.0 Ag-1.This excellent performances can be ascribed to the novel fiber architecture and Cu introduction. Cu nanocrystal in the CNFs ensures the composite a good conductive ability.
