A freestanding SnO 2 @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 SnO 2 @N‐CNF still delivers 245.9 mAh g −1 .
