Electrochemical double layer capacitors (EDLCs), one type of supercapacitors, are eco-friendly because they charge and discharge using ion adsorption of electrodes and electrolytes. However, since the performance depends on the surface area of the carbon electrode, the surface area should be increased without collapsing the internal structure. In this study, 6FDA (4,4-(Hexafluoroisopropylidene)-diphthalic Anhydride) and Durene-diamine (2,3,5,6-Tetramrthyl-1,4-phenylenediamine) are synthesized and PVDF (Poly(vinylidene fluoride)) is blended to make large pores in the heat treatment process to make the surface area wider. These supercapacitors have improved cyclic stability and charge-discharge capability as well as capacitance. |
