Na　super-ion　conductor　type　material　Na3V2(PO4)3　has　been　widely　researched　as　the　cathode　of　sodium-ion　batteries　(SIBs)　in　recent　years,　but　the　unsatisfying　cost　of　Na3V2(PO4)3　impedes　its　wide　application　in　SIBs.　In　this　study,　iron　element　is　used　to　replace　part　of　vanadium　in　Na3V2(PO4)3　to　reduce　its　expense,　and　pine　pollen　is　applied　for　the　first　time　as　a　very　effective　carbon　source　to　improve　the　performance　of　Na4FeV(PO4)3.　The　fabricated　composite　material　achieves　a　capacity　of　105　mA　h　g−1　under　0.2　C　and　fascinating　cycling　stability　over　94　%　under　2　C　for　500　cycles　and　98　%　under　10　C　for　1000　cycles.　The　excellent　cycle　performance　is　caused　by　the　involvement　of　pine　pollen　that　acts　as　a　carbon　matrix　to　enhance　the　electron　conductivity　and　block　the　agglomeration　of　active　material　effectively,　thus　the　well-dispersed　nano　sized　Na4FeV(PO4)3　shortens　the　diffusion　path　of　sodium　ion　and　gains　a　remarkable　rate　capability.　Moreover,　the　distinguished　reversibility　during　the　charge　and　discharge　procedures　is　ascribed　also　to　the　robust　structure　of　Na4FeV(PO4)3.　This　work　provides　an　efficient　route　to　realize　the　economic　cathode　material　of　SIBs　with　good　performance.　©　2024　Elsevier　Inc.
