The second (black), fifth (magenta)and fiftieth (blue) galvanostatic discharge–charge curves of the TSAA (a) and TSAQ (b) at a current density of 50 mA g−1. (c) Cycle performances at a current density of 100 mA g−1 in the voltage range of 3–0.05 V versus Na/Na+; (d) rate performance of TSAA and TSAQ electrodes at various current densities. (e) Cycle performance and the corresponding coulombic efficiency of TSAQ at a current density of 1,000 mA g−1 in the voltage range of 3–0.05 V versus Na+/Na up to more than 2,500 cycles. (f) CV curves of TSAQ at a scanning rate of 1.0, 0.5, 0.25 and 0.1 mV s−1, and the relation between scanning rate and peak current (insert).
