High-Voltage Fe-Based Tunnel-Type Na<sub>0.66</sub>[Mn<sub>0.33</sub>Fe<sub>0.33</sub>Ti<sub>0.3</sub>Sn<sub>0.04</sub>]O<sub>2</sub> Cathode for Aqueous Rechargeable Sodium-Ion Battery

Tunnel-type-structure Na<sub>0.44</sub>MnO<sub>2</sub> has been extensively researched for cathode material in aqueous rechargeable sodium-ion battery owing to its high specific capacity (120 mA h g<sup>-1</sup>), large channels facilitating Na extraction/insertion, chemical and electrochemical stability in aqueous electrolytes, and low cost. However, the low average working potential (0.1 V versus standard hydrogen electrode, SHE) and no more than half of its available theoretical capacity within full batteries limit the practical application. Herein, we develop an Fe-based tunnel-type Na<sub>0.66</sub>[Mn<sub>0.33</sub>Fe<sub>0.33</sub>Ti<sub>0.3</sub>Sn<sub>0.04</sub>]O<sub>2</sub> cathode, delivering a high reversible specific capacity (95 mA h g<sup>-1</sup>) under a high working voltage (0.75 V versus SHE). A full battery, assembled with a NaTi<sub>2</sub>(PO<sub>4</sub>)<sub>3</sub>@C anode, exhibits a high energy density of 80 W h kg<sup>-1</sup> (total mass of cathode and anode active materials) and a long cycle life with 84% capacity retention after 1000 cycles at 1 C.

Abstract

Tunnel-type-structure Na<sub>0.44</sub>MnO<sub>2</sub> has been extensively researched for cathode material in aqueous rechargeable sodium-ion battery owing to its high specific capacity (120 mA h g<sup>-1</sup>), large channels facilitating Na extraction/insertion, chemical and electrochemical stability in aqueous electrolytes, and low cost. However, the low average working potential (0.1 V versus standard hydrogen electrode, SHE) and no more than half of its available theoretical capacity within full batteries limit the practical application. Herein, we develop an Fe-based tunnel-type Na<sub>0.66</sub>[Mn<sub>0.33</sub>Fe<sub>0.33</sub>Ti<sub>0.3</sub>Sn<sub>0.04</sub>]O<sub>2</sub> cathode, delivering a high reversible specific capacity (95 mA h g<sup>-1</sup>) under a high working voltage (0.75 V versus SHE). A full battery, assembled with a NaTi<sub>2</sub>(PO<sub>4</sub>)<sub>3</sub>@C anode, exhibits a high energy density of 80 W h kg<sup>-1</sup> (total mass of cathode and anode active materials) and a long cycle life with 84% capacity retention after 1000 cycles at 1 C.
