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.
