Flexible aqueous Zn-ion batteries have aroused great interest as an emerging energy storage technology in smart/wearable electronics due to their low cost, high energy density, good safety, and flexibility. However, the construction of excellent cathode and anode is still a key step for the Zn-ion batteries development. Herein, we report a rechargeable flexible quasi-solid-state (FQSS) Zn-ion battery assembled with free-binder polyaniline/molecular-decorated carbon cloth (PANI/mCC) cathode and zinc nanosheet/CC (Zn/CC) anode sandwiched by poly(vinyl alcohol)/Zn(CF₃SO₃)₂ gel electrolyte. The nanostructured PANI arrays and Zn sheets oriented on the flexible substrates afford rapid transport channels for electrolyte ions and endow electrodes enough flexibility. Consequently, the constructed FQSS Zn-ion battery exhibits outstanding energy/power densities of 185.7 Wh kg⁻¹/9742 W kg⁻¹ and good capacity retention of 80% after 1000 charge-discharge cycles at 3.3 C. Impressively, the assembled flexible device can accommodate a series of bending states and show stable performance.

柔性水性Zn离子电池因其低成本，高能量密度，良好的安全性和灵活性而作为智能/可穿戴电子产品中的新兴储能技术引起了人们极大的兴趣。然而，优良的正极和负极的构造仍然是锌离子电池发展的关键步骤。在此，我们报告了一种可充电柔性准固态（FQSS）Zn离子电池，该电池由自由结合的聚苯胺/分子装饰碳布（PANI / mCC）阴极和锌纳米片/ CC（Zn / CC）阳极夹在中间，由聚乙烯醇/ Zn（CF ₃ SO ₃）₂凝胶电解质。纳米结构的PANI阵列和定向在柔性基板上的Zn片提供了用于电解质离子的快速传输通道，并赋予了电极足够的柔性。因此，所构造的FQSS锌离子电池在3.3 C的1000次充放电循环后，具有出色的能量/功率密度185.7 Wh kg ^-1 / 9742 W kg ^-1和良好的80％容量保持率。可以适应一系列弯曲状态并显示稳定的性能。
