Aqueous rechargeable Zn-ion batteries (ZIBs) are safe, low cost, and environmentally friendly, yet the realization of both high capacity and long cycling life remains a major challenge. Herein, electrodeposited poly(1,5-naphthalenediamine) nanorods over nanoporous carbon are used as the cathode material to make aqueous ZIBs that can be operated within the voltage range of 0.1 – 1.8 V and have merits of both ionic battery and supercapacitor. Flexible carbon fiber fabric and thick carbon fiber felt are used as current collectors, respectively, to support the polymer/carbon composite with different mass loadings. With using the carbon fabric, flat pouch cells and cable-shaped micro cells are fabricated and show stable electrochemical performances when repeatedly bent at large angles. The pouch cells show maximum energy and power densities of 195 Wh kg^‒1 and 10⁴ W kg^–1, respectively, and achieve a capacity retention of 91% after 10000 cycles. The prototype cell with using a 3 mm-thick carbon felt shows higher energy densities up to 7.7 mWh cm^‒2 and better cycling stability, i.e., 100% capacity retention after 10000 cycles. Also, insights into the charge storage mechanism and superb cycling stability of our new polymer cathode are given.

水性可充电锌离子电池（ZIBs）安全，成本低廉且环保，然而实现高容量和长循环寿命仍然是一项重大挑战。在此，将纳米多孔碳上的电沉积聚（1,5-萘二胺）纳米棒用作阴极材料，以制备水性ZIBs，该ZIBs可在0.1 – 1.8 V的电压范围内操作，并具有离子电池和超级电容器的优点。柔性碳纤维织物和厚碳纤维毡分别用作集电器，以支持具有不同质量负载的聚合物/碳复合材料。使用碳纤维织物制成扁平袋式电池和电缆状微电池，当以大角度反复弯曲时，它们显示出稳定的电化学性能。袋式电池的最大能量和功率密度为195 Wh kg^{分别为‒1}和10 ⁴ W kg ^–1，并在10000次循环后达到91％的容量保持率。使用厚度为3 mm的碳毡的原型电池显示出更高的能量密度，高达7.7 mWh cm ^‒2和更好的循环稳定性，即10000次循环后的100％容量保持率。此外，还对我们的新型聚合物阴极的电荷存储机理和出色的循环稳定性提供了见解。
