Oxygen　vacancies　(OVs)　are　reported　for　the　first　time　as　an　effective　strategy　to　boost　the　electrochemical　performance　for　amorphous　electrode　materials　of　sodium-ion　batteries　(SIB).　Amorphous　SnO2　is　used　as　a　model　anode　material　to　demonstrate　the　significant　impact　of　OVs　because　it　has　received　much　attention　in　the　SIB　field.　Amorphous　SnO2　ordered　arrays　are　fabricated　using　the　nanoimprinted　anodic　aluminum　oxide　(AAO)　template　and　atomic　layer　deposition　and　OVs　are　confined　in　the　material　by　annealing　the　arrays　in　the　N-2　atmosphere.　The　OVs-containing　amorphous　SnO2　ordered　arrays,　used　as　binder-and　conductive　additive-free　anodes,　exhibit　high　reversible　capacity　and　good　cycle　life　by　retaining　the　capacities　of　376　mAh　g(-1)　after　100　cycles　at　0.05　A　g(-1)　and　220　mAh　g(-1)　after　800　cycles　at　1　A　g(-1).　They　also　show　great　rate　capability　by　delivering　the　capacities　of　210　and　200　mAh　g(-1)　at　10　and　20　A　g(-1),　respectively.　Electrochemical　kinetic　study　reveals　that　the　presence　of　OVs　greatly　enhances　charge　transfer/transport　in　the　amorphous　SnO2,　thereby　boosts　the　performance　comparing　with　the　OVs-free　counterpart.　This　work　highlights　the　importance　of　modulating　defects　in　amorphous　electrode　materials　toward　promoted　sodium　storage.
