Abstract

A freestanding SnO2@N-CNF film prepared by electrospinning exhibits excellent flexibility and a high surface area of 506 m(2) g(-1). When used as an anode for lithium-ion batteries, a high reversible capacity of 754 mAh g(-1) is maintained after the 300(th) cycle at 1 A g(-1) . Even when the current density increases to 5 A g(-1), the SnO2@N-CNF still delivers 245.9 mAh g(-1).

Keywords: Li-ion batteries; carbon nanofibers; flexible electrode; long cycle life; superior rate capacity.
