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