Porous carbon nanofiber (CNF)‐supported tin‐antimony (SnSb) alloys are synthesized and applied as a sodium‐ion battery anode. The chemistry and morphology of the solid electrolyte interphase (SEI) film and its correlation with the electrode performance are studied. The addition of fluoroethylene car...
