Lightweight, high-performance supercapacitors are in great demand in applications including hybrid electric vehicles and wearable electronics. Electrode materials play a very decisive role in determining the electrochemical performance as well as the mass of the supercapacitor. Electronically conducting polymers based pseudocapacitors have commanded much interest in the quest for the realisation of flexible, lightweight devices with high specific capacitance. Reports on the use of pristine polyaniline (PANI) electrodes for supercapacitors are rare due to their low cycling stability. Here, we report the synthesis of pristine crystalline PANI by self-stabilised dispersion polymerisation (SSDP) and its use as electrodes for supercapacitors using a redox-active electrolyte. The SSDP PANI electrode exhibits a gravimetric capacitance of 437.8 F g⁻¹ at a current density of 0.5 A g⁻¹ in the H₂SO₄-hydroquinone electrolyte. The pristine PANI supercapacitor exhibits a capacitance retention of 98.3 % even after continuous 8500 charge-discharge cycles performed at a current density of 5 A g⁻¹. The incredibly high areal capacitance of 875.6 mF cm⁻² at 1 mA cm⁻² and long cycling stability observed in these lightweight pristine polymer supercapacitors can be used to power up wearable integrated devices.

轻质、高性能的超级电容器在混合动力电动汽车和可穿戴电子产品等应用中的需求量很大。电极材料在决定超级电容器的电化学性能和质量方面起着非常决定性的作用。基于导电聚合物的赝电容器在寻求实现具有高比电容的柔性、轻量级设备方面引起了极大的兴趣。由于其低循环稳定性，关于将原始聚苯胺 (PANI) 电极用于超级电容器的报道很少。在这里，我们报告了通过自稳定分散聚合 (SSDP) 合成原始结晶 PANI，并将其用作使用氧化还原活性电解质的超级电容器电极。SSDP PANI 电极的重量电容为 437.8 F g^-1在H ₂ SO ₄ -对苯二酚电解质中在0.5 A g ^{-1的电流密度下。即使在以 5 A g -1}的电流密度执行连续 8500 次充放电循环后，原始 PANI 超级电容器仍表现出 98.3% 的电容保持率。^{在这些轻质原始聚合物超级电容器中观察到的 875.6 mF cm -2}在 1 mA cm ^-2下的令人难以置信的高面积电容和长循环稳定性可用于为可穿戴集成设备供电。
