Abstract

The flexible and rechargeable energy storage device with excellent performance is highly desired due to the demands of portable and wearable devices. Herein, by integrating the bendability and stretchability of Polyvinyl alcohol (PVA), pseudocapacitance of Polyaniline (PANI), and the charge transport ability of carbon nanotubes (CNTs), PVA/CNT/PANI flexible film was fabricated as supercapacitor electrodes with excellent electrochemical performance and flexibility. Full-solid supercapacitor is prepared based on PVA/H₂SO₄ gel electrolyte and as-prepared film electrodes. The device achieves an areal capacitance of 196.5 mF cm^-2 with high cycling stability. The flexible properties of PVA, the conductivity of CNT, and the pseudo-capacitance of PANI contribute to the superior performance. Present work develops a facile and effective way for preparing flexible electrode materials.

PVA / CNT / PANI柔性薄膜作为超级电容器电极的制备和电化学性能。

摘要

由于便携式和可穿戴设备的需求，非常需要具有优异性能的柔性可再充电能量存储设备。在此，通过将聚乙烯醇（PVA）的弯曲性和拉伸性，聚苯胺（PANI）的假电容以及碳纳米管（CNT）的电荷输送能力综合起来，制成具有优异电化学性能的PVA / CNT / PANI柔性膜作为超级电容器电极。和灵活性。基于PVA / H ₂ SO ₄凝胶电解质和制备的膜电极制备全固态超级电容器。该器件实现了196.5 mF cm ^-2的面电容循环稳定性高。PVA的柔韧性，CNT的电导率和PANI的假电容有助于提高性能。当前的工作为制备柔性电极材料开发了一种简便有效的方法。
