Sodium　metal　batteries　are　arousing　extensive　interest　owing　to　their　high　energy　density,　low　cost　and　wide　resource.　However,　the　practical　development　of　sodium　metal　batteries　is　inherently　plagued　by　the　severe　volume　expansion　and　the　dendrite　growth　of　sodium　metal　anode　during　long　cycles　under　high　current　density.　Herein,　a　simple　electrospinning　method　is　applied　to　construct　the　uniformly　nitrogen-doped　porous　carbon　fiber　skeleton　and　used　as　three-dimensional　(3D)　current　collector　for　sodium　metal　anode,　which　has　high　specific　surface　area　(1,098　m2/g)　and　strong　binding　to　sodium　metal.　As　a　result,　nitrogen-doped　carbon　fiber　current　collector　shows　a　low　sodium　deposition　overpotential　and　a　highly　stable　cyclability　for　3,500　h　with　a　high　coulombic　effciency　of　99.9%　at　2　mA/cm2　and　2　mAh/cm2.　Moreover,　the　full　cells　using　carbon　coated　sodium　vanadium　phosphate　as　cathode　and　sodium　pre-plated　nitrogen-doped　carbon　fiber　skeleton　as　hybrid　anode　can　stably　cycle　for　300　times.　These　results　illustrate　an　effective　strategy　to　construct　a　3D　uniformly　nitrogen-doped　carbon　skeleton　based　sodium　metal　hybrid　anode　without　the　formation　of　dendrites,　which　provide　a　prospect　for　further　development　and　research　of　high　performance　sodium　metal　batteries.　[Figure　not　available:　see　fulltext.].　©　2020,　Tsinghua　University　Press　and　Springer-Verlag　GmbH　Germany,　part　of　Springer　Nature.
