We fabricated Sn-Sb-carbon (SSC)-based hybrid nanocomposite fibers by electrospinning and carbonization. These SSC fibers which are multiphase SnSb nanoparticles on SnO2/Sn/C nanofibers exhibited enhanced electrochemical performances. Their favorable Li- and Na-storage capacities could be attributed to the synergistic effects of zero-dimensional and one-dimensional hybrid structures offering improved electric conductivity and large surface area.
