High Performance Titanium Antimonide TiSb2 Alloy for Na-Ion Batteries and Capacitors

Chemistry of Materials, 2018
Herein, we report for the first time the use of TiSb2 alloy as anode material for sodium-ion batteries (NIBs) and capacitors (NICs). The electrochemical performance of TiSb2 in NIBs shows stable cycling with a capacity of about 225 mAh·g–1 for 200 cycles.
