A　new　type　of　platelet-like　ammonium　vanadium　bronze　(NH4)2V6O16　is　first　used　as　cathode　material　for　Na-ion　battery.　The　discharge　capacity　and　cycling　stability　is　improved　by　the　intercalation　of　Na+　and　using　NaPF6　as　electrolyte.　Raman　spectrum　shows　that　the　crystalline　structure　of　(NH4)2V6O16　is　changed　after　the　intercalation　of　Na+　to　(NH4)2V6O16.　Furthermore,　the　obtained　sodium　ammonium　vanadium　bronze　shows　smaller　charge　transfer　resistance　than　(NH4)2V6O16,　which　would　favor　superior　discharge　capacity　and　good　cycling　stability.　Additionally,　NaPF6　is　prior　to　NaClO4　as　electrolyte　for　ammonium　vanadium　bronze　cathode　materials.　©　2013　Elsevier　Inc.
