Abstract
Na2Ti3O7 has been known for a long time and studied for several applications in sensors, catalysis and in toxic waste removal. The applicability of Na2Ti3O7 as an anode material for rechargeable Na-ion batteries was investigated in this study. Na2Ti3O7 nano fibers were synthesized by hydrothermal technique and characterized by using X-ray diffraction and scanning electron microscopy. The results show that spherical Na2Ti3O7 materials consisting of tiny nano fibers have been formed. The electrochemical characterization was performed with Na metal electrode in coin half-cells fabricated in an Ar inert atmosphere. The galvanostatic charge-discharge measurements in the voltage range of 0.02 - 1.9 V revealed the initial discharge capacity of 787.2 mAhg-1 at C / 10 rate and the discharge capacity was decreased to 55 mAhg-1 over 30 cycles. The results suggest that the crystalline Na2Ti3O7 nano fibers are suitable to be used as an anode material in rechargeable Na-ion batteries.
