A　simple　and　versatile　method　for　preparation　of　novel　sodium　intercalated　(NH4)2V6O16　is　developed　via　a　simple　hydrothermal　route.　It　is　found　that　ammonium　sodium　vanadium　bronze　displays　higher　discharge　capacity　and　better　rate　cyclic　stability　than　ammonium　vanadium　bronze　as　lithium-ion　battery　cathode　material　because　of　smaller　charge　transfer　resistance,　which　would　favor　superior　discharge　capacity　and　rate　performance.　©　2013.
