Abstract

Highly porous CoFe₂O₄ nanofibers were synthesized by an electrospinning process followed by a calcination step. The CoFe₂O₄ nanofibers were highly porous and polycrystalline with an average diameter of 223 nm and a high aspect ratio. A lithium ion battery with its anode fabricated from the electrospun CoFe₂O₄ nanofibers was developed. The battery exhibited a specific capacity as high as 660 mAh g⁻¹ after 100 cycles and a coulombic efficiency of over 95%.
