A flexible membrane consisting of MoS2/carbon nanofibers has been fabricated by a simple electrospinning method. MoS2 nanosheets are uniformly encapsulated in the inter-connected carbon nanofibers with diameters of, 150 nm. When evaluated as a binder-free electrode for sodium-ion batteries, the as-obtained electrode demonstrates high performances, including high reversible capacity of 381.7 mAh g(-1) at 100 mA g(-1) and superior rate capability (283.3, 246.5 and 186.3 mA h g(-1) at 0.5, 1 and 2 A g(-1), respectively). Most importantly, the binder-free electrode made of MoS2 and carbon nanofibers can still deliver a charge capacity of 283.9 mA h g(-1) after 600 cycles at a current density of 100 m A g(-1), indicating a very promising anode for long-life SIBs.
