Carbon-supported　SnS　composite　was　prepared　via　a　solvothermal　process　followed　by　thermal　calcination.　The　carbon　nanosheets　could　not　only　ensure　electron　conduction　within　the　composite　but　also　alleviate　the　volume　change　of　SnS　during　the　charging/discharging　process.　As　a　result,　when　employed　as　an　anode　material　for　potassium-ion　batteries,　the　composite　delivers　good　potassium　storage　performance.　In　detail,　at　a　current　density　of　100　mA　g−1,　its　capacity　is　still　higher　than　102.6　mAh　g−1　after　50　cycles.　In　terms　of　long-cycling　stability,　76.1　mAh　g−1　was　obtained　after　200　cycles　at　200　mA　g−1.　©　2021　Elsevier　Ltd
