Tin disulfide embedded in N-, S-doped carbon nanofibers as anode material for sodium-ion batteries

In this work, tin disulfide (SnS2) embedded in nitrogen and sulfur dual-doped carbon (denoted as SnS2/NSDC) nanofibers are synthesized using a facile electrospinning technique for the first time. The exterior of the nanofibers is decorated through the SnS2 nanosheet, and the interior of carbon nanofibers is embedded with SnS2 nanoparticles. Benefit from the unique structure and morphology, SnS2/NSDC nanofibers show excellent electrochemical...
