Na_2Ti_6O_(13) Thin films as Anode for Thin Film Sodium Ion Batteries

摘要

The pulsed laser deposition was employed to produce Na_2Ti_6O_(13) (NTO) thin films, which were applied as an anode material for Sodium-Ion batteries (SIBs). X-ray diffraction made it clear that the film is crystalline in single phase. Morphology and elemental composition studies were done using FESEM. Grain size and surface roughness was measured from atomic force microscopy. The electrochemical measurements were performed at 0.5 - 3V range and it exhibited the initial discharge capacity was 49.7 μAh/μm-cm~2 with coulombic efficiency 69.8%.
