A simple cost-effective wet synthesis route has been proposed for synthesis of Na2Ti6O13, which is an efficient anode material that can be used for 1�3 volt batteries. The material has been synthesized by sonochemical route, which offers two distinct features: (1) energy-savvy (green) synthesis by significantly lowering the final calcination temperature and duration, and (2) formation of uniform and nano-scale particles suitable for battery application. The sonochemical synthesis was carried out at 20 kHz�500 W by applying sonication for 30 min at 25°C, using precursors (NaOH:TiO2) in a molar ratio of 6:1 followed by calcination at 750°C for 1 h in air. This material showed excellent reversible electrochemical performance (up to 93 retention) and offers reversible capacity around 40 mAh g�1 acting to be 0.82 V anode for Na-ion battery. © 2020, Indian Academy of Sciences.
