The　synergetic　mechanism　of　chemisorption　and　catalysis　play　an　important　role　in　developing　high-performance　lithium-sulfur　(Li-S)　batteries.　Herein,　a　3D　lather-like　porous　carbon　framework　containing　Fe-based　compounds　(including　Fe3C,　Fe3O4,　and　Fe2O3),　named　FeCFeOC,　is　designed　as　the　sulfur　host　and　the　interlayer　on　separator.　Due　to　the　strong　chemisorption　and　catalytic　ability　of　FeCFeOC　composite,　the　soluble　lithium　polysulfides　(LiPSs)　are　first　adsorbed　and　anchored　on　the　surface　of　the　FeCFeOC　composite　and　then　are　catalyzed　to　accelerate　their　conversion　reaction.　In　addition,　the　FexOy　in　Fe-based　compounds　can　spontaneously　react　with　LiPSs　to　form　magnetic　FeSx　species　with　a　larger　size,　further　blocking　the　penetration　of　LiPSs　cross　the　separator.　As　a　result,　the　assembled　Li-S　cells　show　excellent　long-term　stability　(748　mAh　g(-1)　over　500　cycles　at　1.0　C,　and　approximate　to　0.036%　decay　per　cycle　for　1000　cycles　at　3.0　C),　a　superb　rate　capability　with　659　mAh　g(-1)　at　5.0　C,　and　lower　electrochemical　polarization.　This　work　introduces　a　feasible　strategy　to　anchor　and　accelerate　the　conversion　of　LiPSs　by　designing　the　multifunctional　Fe-based　compounds　with　high　chemisorption　and　catalytic　activity,　which　advances　the　large-scale　application　of　high-performance　Li-S　batteries.
