In recent years, orthorhombic Nb₂O₅ (T-Nb₂O₅) has been considered as a promising anode material for sodium-ion hybrid capacitors (SICs) due to its fast ion storage properties. Moreover, the T-Nb₂O₅ has a strong adsorption effect with sulfur species, which shows merits for efficient management of polysulfides in lithium–sulfur (Li–S) batteries. Herein, we in target prepared T-Nb₂O₅ nanowires (T-Nb₂O₅ NWs) and systematically analyzed the electrochemical performances with regards to SICs and Li–S batteries. The resulting T-Nb₂O₅ NWs//activated carbon SICs delivered a high energy density (106.2 Wh kg⁻¹) and power density (4976 W kg⁻¹). Thus-derived flexible SICs manifested excellent performances upon deformation, which was applicable for fast-charging wearable electronic sensors. Meanwhile, Li–S batteries incorporating T-Nb₂O₅/graphene/sulfur cathode offered a discharge capacity of 1300 and 917.1 mAh g⁻¹ at 0.2 and 1C, respectively.

近年来，由于其快速的离子存储特性，正交晶Nb ₂ O ₅（T -Nb ₂ O ₅）被认为是钠离子混合电容器（SIC）的有希望的阳极材料。此外，T -Nb ₂ O ₅对硫物质具有很强的吸附作用，这显示了有效管理锂硫（Li– S）电池中多硫化物的优点。在此，我们以目标制备的T -Nb ₂ O ₅纳米线（T -Nb ₂ O ₅NWs）并系统地分析了SIC和Li-S电池的电化学性能。所得的T -Nb ₂ O ₅ NWs //活性炭SIC传递了高的能量密度（106.2 Wh kg ^-1）和功率密度（4976 W kg ^-1）。因此衍生的柔性SIC在变形时表现出出色的性能，适用于快速充电的可穿戴电子传感器。同时，掺有T -Nb ₂ O ₅ /石墨烯/硫阴极的Li- S电池在0.2和1C时的放电容量分别为1300和917.1 mAh g ^-1。
