Insufficient energy density and poor cyclic stability is still challenge for conductive polymer-based supercapacitor. Herein, high performance electrochemical system has been assembled by combining poly (3,4-ethylenedioxythiophene) (PEDOT):poly (styrene sulfonate) (PSS) redox electrode and potassium iodide redox electrolyte, which provide the maximum specific capacity of 51.3 mAh/g and the retention of specific capacity of 87.6% after 3000 cycles due to the synergic effect through a simultaneous redox reaction both in electrode and electrolyte, as well as the catalytic activity for reduction of triiodide of the PEDOT:PSS.
能量密度不足和循环稳定性差仍是基于导电聚合物的超级电容器面临的挑战。在此，通过将聚（3,4-乙撑二氧噻吩）（PEDOT）：聚（苯乙烯磺酸盐）（PSS）氧化还原电极与碘化钾氧化还原电解质相结合，组装了高性能电化学系统。由于电极和电解质中同时发生氧化还原反应产生的协同效应，以及PEDOT：PSS对三碘化物还原的催化活性，该系统提供了51.3 mAh/g的最大比容量，并且在3000次循环后比容量保留率为87.6%。
