Abstract

Composites of carbon nanofibers (CNFs) and nanophase Pt-SnO₂ were synthesized using electrospinning followed by carbonization, for use as anode materials in Lithium-ion batteries (LIBs). Composites of CNFs and nanophase Pt-SnO₂ (sample B) exhibit the highest capacity (~621.9 mAh/g at the 50th cycle) and excellent cyclic stability as compared to conventional CNFs and composites of CNFs and nanophase SnO₂ (sample A). The result indicates that the improvement in performance of CNFs by the incorporation of nanophase Pt-SnO₂ can be explained by the enhancement in electrical conductivity and the increase in the number of electrochemical active sites.
