All-in-one supercapacitors show broader application prospect in the field of flexible electronics due to the electrochemical stability and durability. Nonetheless, how to simultaneously enhance the output voltage and capacitance of integrated devices while maintain excellent flexibility and reasonable dimension is a critical challenge for the further development and application of all-in-one supercapacitor. In this work, the self-integrated all-in-one fabric-based supercapacitors (FSCs) with excellent capacitive behavior, flexibility and scalability are designed and fabricated by simply screen-printing the multi-walled carbon nanotubes (MWCNTs) ink on both sides of fabric-based composite separator. The interlocked-like electrode configuration of self-integrated FSC enables electrolyte ions to be transported in transverse and perpendicular directions, and it greatly improved the areal capacitance and reduced internal resistance. Moreover, the assembled FSC exhibits excellent flexibility and stability even under dynamic bending with relatively high strain rates (20% s⁻¹), and 86.1% capacitance is maintained after 1000 bending cycles. Most importantly, the simultaneous series and parallel integration scheme of self-integrated FSCs is realized by versatile screen-printing technique, demonstrating the great potential to simultaneously improve output voltage, overall capacity and potability in a relatively small dimension. Generally, the unique electrode configuration proposes a cost-effective strategy for mass production of flexible energy storage devices.

一体式超级电容器由于其电化学稳定性和耐久性，在柔性电子领域显示出更广阔的应用前景。尽管如此，如何同时提高集成器件的输出电压和电容，同时保持出色的灵活性和合理的尺寸，是一体化超级电容器进一步发展和应用的关键挑战。在这项工作中，通过简单地在两侧丝网印刷多壁碳纳米管 (MWCNT) 墨水，设计和制造了具有出色电容行为、灵活性和可扩展性的自集成一体式基于织物的超级电容器 (FSC)基于织物的复合隔膜。自集成FSC的互锁状电极配置使电解质离子能够在横向和垂直方向上传输，大大提高了面电容并降低了内阻。此外，即使在应变率相对较高（20% s⁻¹ )，并且在 1000 次弯曲循环后保持 86.1% 的电容。最重要的是，自集成 FSC 的同步串联和并联集成方案是通过多功能丝网印刷技术实现的，展示了在相对较小的尺寸内同时提高输出电压、总容量和可饮用性的巨大潜力。通常，独特的电极配置为柔性储能设备的大规模生产提供了一种具有成本效益的策略。
