The charge/discharge characteristics of NaTi2(PO 4)3 as an anode active material for aqueous sodium-ion battery containing 2 M Na2SO4 aqueous electrolyte were examined. Cyclic voltammograms, galvanostatic discharge/charge and XRD data of the material indicated that sodium can be reversibly intercalated into NASICON-type NaTi2(PO4)3 without serious degradation of the host structure. The best reversible capacity at rate of 2.0 mA cm-2 was 93 of the theoretical capacity of 133 mAh g-1 and the plateau voltage was 2.1 V versus Na/Na.
