Various carbon-carbon EDLCs were assembled with ionic polymers of perfluorosulphonic acid polymer in the H+, Na+ and K + forms, composites of polytetrafluoro ethylene (PTFE) and perfluorosulphonic acid, PVA-KOH, sulphonated PEEK and PVdF. The surface area of the carbon used in these EDLCs is 260 m2/gm. CV, EIS and discharge profiles were used for characterization. The working voltage of these EDLCs was 2V. The specific capacitance was found to be 20 F/g, 40 F/g and 55 F/g for the perflurosulphonic acid electrolyte in H+, Na+ and K +, respectively. A specific capacitance of 16 F/g was obtained for the EDLC with the composite of PTFE/perluorosulphonic acid and 7.5 F/g and 1.0 F/g for PVA-KOH and sulphonated PEEK electrolyte, respectively. Modules of 5F (2.0V) were developed using carbon electrodes and composites of PTFE/perflurosulphonic as electrolyte. The maximum energy stored in these modules, was of the order of 7.5 Watth/kg. ©The Electrochemical Society.
