Coaxial carbon nanofiber/NiO core–shell nanocables as anodes for lithium ion batteries

The CNF/NiO core–shell nanocables are prepared by electrospinning and electrophoretic deposition. The CNF/NiO nanocables deliver a high reversible capacity of 825 mA h g ⁻¹ at 200 mA g ⁻¹ after 50 charge–discharge cycles without showing obvious decay.
