In the present work, results on the synthesis and mass production of polymer/ceramic composite fibers through Forcespinning® (FS) are reported. Magnetite (Fe3O4), has been considered as a good anode material for Lithium‒Ion Batteries (LIBs) due to its high theoretical capacity (~924 mAhg-1), low cost, and low toxicity. The Fe3O4/carbon composite, in the present study, was achieved through Forcespinning iron (III) acetylacetonate /polyacrylonitrile (PAN) precursor solution with stabilization in air at 280°C followed by carbonization at 600°C under argon. The electrochemical cyclic performance of Fe3O4/C composite fibers was investigated by galvanostatic charge/discharge experiments. The results showed the Fe3O4/C composite fiber anode exhibited higher reversible capacity of 300 mAhg-1 after 100 cycles at a current density of 100 mAg-1 compared to that of carbon fibers, which was approximately100 mAhg-1. In addition, the Fe3O4/composite fiber anode showed improved capacity retention and better rate performance than pure carbon fibers.
