Fabrication of biowaste derived carbon-carbon based electrodes for high-performance supercapacitor applications

摘要: The porous carbon is synthesised by chemical activation using cork dust bio-waste as source and the electrochemical performance of resulting material tested in even uneven weight configuration a two-electrode system. obtained derived activated (CDAC) shown unique honeycomb structured morphology confirmed morphological analysis. X-ray diffraction (XRD) Raman characterisation revealed graphitic nature CDAC. Furthermore, CDAC exhibited high specific surface area (1707 m2/g) large pore volume (2.4 cc/g) with an average size 4 nm. Even supercapacitor cell (SC) (positive negative electrode same weight) SC (weight ratio positive/negative electrodes:1.2) are assembled 1M TEABF4/AN. Uneven delivers highest capacitance value 107 F/g at current density 1 A/g. device shows promising cyclic stability without significant changes values after 10000 5000 charge-discharge cycles potential window 3 V 3.2 V, respectively. On contrary, less (87 A/g) observed for though high-capacity retention realised under experimental conditions. enhanced attributed to balancing electrode, nature, distribution interconnected
