Bismuth　has　emerged　as　a　promising　anode　material　for　sodium-ion　batteries　(SIBs),　owing　to　its　high　capacity　and　suitable　operating　potential.　However,　large　volume　changes　during　alloying/dealloying　processes　lead　to　poor　cycling　performance.　Herein,　bismuth　nanoparticle@carbon　(Bi@C)　composite　is　prepared　via　a　facile　annealing　method　using　a　commercial　coordination　compound　precursor　of　bismuth　citrate.　The　composite　has　a　uniform　structure　with　Bi　nanoparticles　embedded　within　a　carbon　framework.　The　nanosized　structure　ensures　a　fast　kinetics　and　efficient　alleviation　of　stress/strain　caused　by　the　volume　change,　and　the　resilient　and　conductive　carbon　matrix　provides　an　interconnected　electron　transportation　pathway.　The　Bi@C　composite　delivers　outstanding　sodium-storage　performance　with　an　ultralong　cycle　life　of　30　000　cycles　at　a　high　current　density　of　8　A　g−1　and　an　excellent　rate　capability　of　71%　capacity　retention　at　an　ultrahigh　current　rate　of　60　A　g−1.　Even　at　a　high　mass　loading　of　11.5　mg　cm−2,　a　stable　reversible　capacity　of　280　mA　h　g−1　can　be　obtained　after　200　cycles.　More　importantly,　full　SIBs　by　pairing　with　a　Na3V2(PO4)3　cathode　demonstrates　superior　performance.　Combining　the　facile　synthesis　and　the　commercial　precursor,　the　exceptional　performance　makes　the　Bi@C　composite　very　promising　for　practical　large-scale　applications.　©　2019　WILEY-VCH　Verlag　GmbH　&　Co.　KGaA,　Weinheim
