Graphene mono- or bi-layers highly scattered in porous carbon nanofibers are preparedviaan electrospinning technique. The nanocomposite with a flexible membrane tightly adherent on Cu foil is directly used as a binder-free anode for Na-ion batteries, demonstrating high reversible capacity, unprecedented rate capability, and ultra-long cycling life.
