Elaborative Studies on Non-Porous Carbon Material for Super Capacitor Application

摘要

This study demonstrates a simplistic and e?ectual approach to prepare non-porous carbon for which nitrogen is doped in poly(vinyl chloride)(PVC)in presence of catalyst cobalt chloride(COCl2).Characterization of the prepared non-porous carbon is carried out using Raman,X-ray di?raction,di?erential 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 ?lter paper is used as a separator.Six times increment is found in the speci?c capacitance value of EDLC prepared using nitrogen-doped carbon(NC-CO)than prepared using pure PVC.The calculated speci?c capacitance values using low-frequency impedance spectroscopy are 62.28 and 7 F g~(-1),respectively,for NC-CO and pure PVC.
