近年来，已经致力于实现薄，用于可穿戴电子产品的轻质甚至灵活的能量存储设备在这里，我们展示了一种新型的全固态超级电容器配置，其具有极其简单的工艺，使用两个稍微分开的聚苯胺基电极，在H2SO 4中固化良好，聚乙烯醇凝胶电解质enure设备的厚度与一张商业标准A4打印纸相当。（扭转）状态下，该集成器件显示出电极材料的350 F/g的高比电容、1000次循环后良好的循环稳定性和小至172 μ A的漏电流。此外，由于其基于聚合物的组件结构，整个器件的比容量高达31.4F/g，是目前高水平商用超级电容器产品的6倍以上。这种高柔性、全固态的类纸聚合物超级电容器，可能为未来可穿戴电子领域的储能器件的器件结构设计带来新的机遇。
In recent years, much effort have been dedicated to achieve thin, lightweight and even flexible energy-storage devices for wearable electronics Here we demonstrate a novel kind of ultrathin all-solid-state supercapacitor configuration with an extremely simple process using two slightly separated polyaniline-based electrodes well solidified in the H2SO4-polyvinyl alcohol gel electrolyte The thickness of the enure device is much comparable to that of a piece of commercial standard A4 print paper Under its highly flexible (twisting) state, the integrate device shows a high specific capacitance of 350 F/g for the electrode materials, well cycle stability after 1000 cycles and a leakage current of as small as 172 mu A Furthermore, due to its polymer-based component structure, it has a specific capacitance of as high as 31 4 F/g for the entire device, which is more than 6 times that of current high-level commercial supercapacitor products These highly flexible and all-solid-state paperlikc polymer supercapacitors may bring new design opportunities of device configuration for energy-storage devices in the future wearable electronic area
