Sn/carbon composite nanofibers with various compositions were prepared from Sn(II) acetate/polyacrylonitrile (PAN) precursors
by a combination of electrospinning and carbonization methods, and their potential use as anode materials for rechargeable lithiumion
batteries was investigated. The composite electrode derived from 20 wt% Sn(II) acetate/PAN precursor showed excellent electrochemical
properties, including a large reversible capacity of 699 mAh g‾1 and a high capacity retention of 83% in 50 cycles. Sn/carbon
composite nanofibers exhibited enhanced electrochemical performance ascribing to the combination of the properties of both Sn nanoparticles
(large Li storage capability) and carbon matrices (long cycle life), and therefore could be potentially used in high-energy rechargeable
