Fabrication of Electrospun Si/Carbon Composite Nanofibers as Anodes Materials for Lithium-Ion Batteries

Abstract:

Si/carbon nanofibers (Si/CNFs) composite used as the anode materials of lithium-ion battery have been prepared via electrospinning and calcinations treatment. Hydrofluoric acid is used to remove surface oxides of Si particles. SEM observation indicates that silicon particles are uniformly embedded in the carbon nanofibers. X-ray diffraction (XRD), energy dispersive x-ray spectroscopy (EDX) and Raman scattering have been used to analysis the composition and phase of the composite materials. The first reversible capacity of the Si/CNFs composite is 1004 mAh/g, and 390 mAh/g has been remained after 100 cycles. Such Si/CNFs composite could be a promising anode material in lithium ion batteries.
