Sodium‐ion batteries (SIBs) have aroused wide concern due to their potential applications in large‐scale energy‐storage systems. In this work, a hybrid of Fe7S8 nanoparticles/N‐doped carbon nanofibers (Fe7S8/N‐CNFs) is designed and synthesized via electrospinning. As an anode for SIBs, Fe7S8/N‐CNFs...
