Nanocube-like KNiFe(CN)₆ and rugby ball-like NaTi₂(PO₄)₃ are grown on carbon nanotube fibers via simple and mild methods.
A quasi-solid-state fiber-shaped aqueous rechargeable sodium-ion battery based on all binder-free electrodes is successfully assembled for the first time, delivering a high volumetric capacity of 34.21 mAh cm⁻³ and impressive volumetric energy density of 39.32 mWh cm⁻³.
The device delivers superior mechanical flexibility with only 5.7% of initial capacity loss after bending at 90° for over 3000 cycles.

高性能可穿戴水性可充电钠离子电池的所有无粘合剂电极

通过简单温和的方法，在碳纳米管纤维上生长了纳米立方体状的KNiFe（CN）₆和橄榄球状的NaTi ₂（PO ₄）₃。
首次成功组装了基于所有无粘合剂电极的准固态纤维状水性可充电钠离子电池，具有34.21 mAh cm ^-3的高体积容量和39.32 mWh cm的令人印象深刻的体积能量密度⁻³。
该器件具有出色的机械灵活性，在90°弯曲超过3000次后，其初始容量损失仅为5.7％。
