A new kind of soft carbon and hard carbon composite nanofibers were fabricated from isotropic pitch and polyacrylonitrile via simple electrospinning followed by stabilization and carbonization. The obtained fibrous mat was directly used as anodes of lithium-ion batteries without binder added and current collector. The composite nanofibers electrodes display a large reversible capacity of 452 mA h g1 at a current density of 20 mA g1 and a capacity of 255 mA h g1 at 200 mA g1 after 200 cycles. The improved electrochemical performance can be attributed to the unique fibrous structure which will facilitate electrons and ions transfer and the porous structure which will accommodate quantities of lithium ions.
