Synthesis of porous carbon from a PVC polymer and its application in supercapacitors

In this study, the laboratory scale production of activated carbon synthesized from PVC with CoCl 2 and H 3 PO 4 , which is cheaper and has a good yield source material, is reported. A prototype supercapacitor was successfully developed using activated carbon as an electrode material derived from the PVC polymer and IL (1-ethyl-3-methylimidazolium thiocyanate) as the electrolyte. The performance of the supercapacitor was estimated via electrochemical impedance spectroscopy, cyclic voltammetry, and the charge-discharge technique. The supercapacitor offered a high specific capacitance of ∼120 F g −1 at 5 m V s −1 . The performances of the supercapacitor were also estimated up to 15 days and up to 9000 cycles via cyclic voltammetry. In this study, the laboratory scale production of activated carbon synthesized from PVC with CoCl 2 and H 3 PO 4 , which is cheaper and has a good yield source material, is reported.
