Resorcinol Formaldehyde Based Carbon Fibers as Anode Material for Lithium Ion Batteries

We hereby introduces electrospun resorcinol-formaldehyde sol based carbon fibers as anode material for Li-ion batteries. To ensure the electrospinnability of resorcinol-formaldehyde sol, we blended it with poly-methyl methacrylate in 2:1 (v/v) ratio followed by controlled pyrolysis. As-prepared thin carbon fibers were then characterized by Raman & Infra-red spectroscopy and scanning electron microscope to examine the crystallinity and morphological changes during the carbonization. Later, we explored the electrochemical properties of these carbon fibers to test them as a potential anode material for lithium ion battery. We found a significant reversible capacity (624 mAh/g) with reasonable higher first cycle efficiency of 65%.
