However, PEDOT's charge storage properties are not impressive. Thus, improvement in charge storage properties of PEDOT will render the possibility of fabricating stable energy storage devices such as supercapacitors. A fundamentally different approach is required to achieve this objective. We envisioned that the charge storage property of PEDOT can be improved by trapping large anions. These ions would facilitate better ion transport into the PEDOT matrix from the electrolyte and increase the efficiency of supercapacitors. Furthermore, a large anion such as triiodide is relatively immobile in the polymer matrix, hence we hypothesize the ions to be trapped in the polymer. To test this hypothesis, triiodide trapped PEDOT based supercapacitors are fabricated on paper substrates. A 1 cm2 triiodide incorporated PEDOT based supercapacitor exhibited a specific capacitance of 486 F/g. On the other hand, PEDOT without triiodide incorporation exhibited a specific capacitance of 221 F/g. Indeed, a device with an area of 32 cm2 exhibited a specific capacitance of 476 F/g.</p>10aFlexible Supercapacitors10aPaper based Supercapacitors10apolyphenols1 aJain, B.1 aKrishnamoorthy, K.  uhttps://library.ncl.res.in/content/large-anion-incorporation-improve-performance-large-paper-based-conducting-polymer00966nas a2200145   4500008004100000245011300041210006900154260000800223300001500231490000800246520040300254100001300657700002300670856012700693       2017                        eng d00aOrganocatalytic Enantioselective Vinylogous Michael-Aldol Cascade for the Synthesis of Spirocyclic Compounds0 aOrganocatalytic Enantioselective Vinylogous MichaelAldol Cascade  cAUG  a 1023-10280 v2463 aNanoscopic spheres of poly(3,4-ethylenedioxythiophene) from its poly(styrene sulfonate) stabilised dispersion was converted to nanofibers by acid treatment.
