SnS2　has　aroused　great　interests　for　application　of　sodium-ion　batteries,　because　of　its　graphene-like　structure　and　high　theoretical　capacity.　Herein,　we　present　an　effective　nanocasting　strategy　to　fabricate　the　SnS2/enteromorpha　prolifera　derived　carbon　(SnS2/EPC)　composite,　whose　microstructure　anchors　the　SnS2　nanosheets　on　enteromorpha　prolifera　(EP)　derived　carbon.　It　can　effectively　solve　the　problems　of　poor　conductivity　and　volume　expansion　of　SnS2　electrode　during　charging　and　discharging　process.　The　optimized　SnS2/EPC　could　deliver　high　reversible　capacity　of　443　mA　h　g−1　at　0.1　A　g−1,　and　maintain　reversible　capacity　of　340　mA　h　g−1　at　high　rate　of　2　A　g−1　after　450　cycles,　indicating　that　SnS2/EPC　is　a　promising　anode　material　for　sodium　storage.　©　2021　Elsevier　Ltd
