This study demonstrates a simplistic and effectual approach to prepare non‐porous carbon for which nitrogen is doped in poly(vinyl chloride) (PVC) in presence of catalyst cobalt chloride (COCl 2 ). Characterization of the prepared non‐porous carbon is carried out using Raman, X‐ray diffraction, differential scanning calorimetry, thermogravimetric analysis, and Brunauer–Emmett–Teller. The calculated surface area of the prepared carbon is 15.78 m 2 g −1 . To compare the performance of prepared non‐porous carbon with pure PVC as an electrode material for supercapacitor application, two EDLC cells are prepared. In both the cells, 1‐ethyl‐3‐methylimidazolium thiocyanate (ionic liquid) is used as an electrolyte and filter paper is used as a separator. Six times increment is found in the specific capacitance value of EDLC prepared using nitrogen‐doped carbon (NC‐CO) than prepared using pure PVC. The calculated specific capacitance values using low‐frequency impedance spectroscopy are 62.28 and 7 F g −1 , respectively, for NC‐CO and pure PVC.
