One of the basic intentions of science and technology is the evolution of novel and more efficient devices to make human life more easy and comfortable. A supercapacitor is one such device that can be utilized as a complementary and to some extent a replacement of electrochemical battery to store electrical energy. The performance of a supercapacitor very much depends on the electrode material used and hence a variety of materials are employed to form electrodes of supercapacitors in order to improve its performance. In this review, we have discussed the preparation and properties of polypyrrole (PPy) and polyindole (PIn) based electrode material for supercapacitor applications. PPy shows a high degree of flexibility which makes it markedly suitable and applicable for making flexible supercapacitors. PIn exhibit slow hydrolytic degradation and hence long charge-discharge time. Thus, PIn can be utilized to form supercapacitors having the ability to store energy for a longer period of time. Nonetheless, their properties can be enhanced by using binary and ternary composites of PPy and PIn with different carbon-based and metal-based materials. This review briefly discusses some of these composites and devices formed by them.

科学技术的基本意图之一是不断发展新颖，更高效的设备，以使人们的生活更轻松，更舒适。超级电容器就是这样一种设备，可以用作电化学电池的补充，并在某种程度上替代电化学电池以存储电能。超级电容器的性能在很大程度上取决于所使用的电极材料，因此为了提高其性能，采用了多种材料来形成超级电容器的电极。在这篇综述中，我们讨论了用于超级电容器的聚吡咯（PPy）和聚吲哚（PIn）基电极材料的制备和性能。PPy显示出高度的灵活性，这使其非常适用于制造柔性超级电容器。PIn显示出缓慢的水解降解，因此具有长的充电-放电时间。因此，可以利用PIN来形成具有较长时间存储能量的能力的超级电容器。尽管如此，通过使用PPy和PIn与不同的碳基和金属基材料的二元和三元复合材料，可以提高其性能。本文简要讨论了其中一些复合材料以及由它们形成的设备。
