Flexible electrode material has bendable feature and can be directly applied as electrode without any additives and binders. In this study, flexible carbon nanofiber/boron nitride composites were prepared via a facile electrospinning and subsequent carbonization treatment for lithium ion battery. BN nanoparticles were uniformly dispersed in the nanofibers after an annealing temperature of 800 °C, and the diameters of nanofibers were at 100~450 nm range. The fabricated composites, used as binder-free anode materials, exhibited an impressive reversible capacity of 205 mAh·g after 300 cycles at a current density of 100 mA·g. The electrodes still exhibited a specific capacity of 140 mAh·g even at a higher current density of 1000 mA·g. The excellent electrochemical performance of the nanofiber/boron nitride composites can be attributed to the unique structure of nanofibers and superior electrical conductivity.
