Sodium-based　dual-ion　batteries　(SDIBs)　have　been　envisaged　as　one　of　the　promising　rechargeable　energy　storage　devices　by　virtue　of　the　low　cost　and　considerably　high　energy　density.　But　the　exploration　of　high-performance　anode　materials　yet　remain　a　grand　challenge.　Herein,　an　elaborate　design　is　reported　to　fabricate　nanohybrids　of　N-doped　carbon　film　modifying　MoSSe　nanosheets　supported　on　hollow　cubic　N-doped　carbon　(MoSSeNSs@NC/hC-NC),　which　features　abundant　anionic　defects,　few-layered　MoSSe　with　expanded　interlayer　spacing,　good　conductivity,　and　hollow　structure.　These　favorable　properties　and　structure　are　greatly　conducive　for　Na+　storage,　as　evidenced　by　displaying　desirable　electrochemical　properties　of　high　capacity,　good　rate　capability,　and　excellent　stability.　The　impressive　capability　for　Na+　storage　in　the　MoSSeNSs@NC/hC-NC　motivates　to　set　up　a　full　SDIBs　device　by　coupling　with　EG　cathode,　which　show　a　discharge　capacity　of　185 mA　h　g–1　at　1　A　g–1　with　the　capacity　retention　of　almost　100%　over　2000　cycles.　©　2021　Wiley-VCH　GmbH.
