In order to achieve exceptional power density and energy density, it is necessary to use materials with high specific surface area as its electrodes. In this study, we prepared a rolled supercapacitor device model using carbon-sheet as the electrodes and 1 M KCl as the electrolyte. A carbon-sheet was soaked in 1 M KCl and assembled as a rolled supercapacitor device model. Performance of the rolled supercapacitor device model was measured using a cyclic voltammetry (CV) in the voltage range of – 0.8 V to + 0.1 V with scanrate variations of 1 mV/s, 5 mV/s, 10 mV/s, 15 mV/s and 20 mV/s. Cyclic voltammetry measurement provide results as follows, Esp = 0.289 to 0.103 Wh/kg and Psp = 5.024 to 35.738 W/kg. By using Ragone plot, we found that the prepared rolled supercapacitor using carbon-sheet as electrodes had met criteria of supercapacitor. The result shows that the carbon-sheet has a good prospect to be used as electrodes for rolled supercapacitor.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Conventional capacitors,Device modeling,Electrolyte systems,Electronic device,High specific surface area,Higher energy density,Power densities,Voltammetry measurements[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Carbon sheet,Cyclic voltammetry,Potassium chloride,Rolled Supercapacitor[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][{‘$’: ‘This result is a part of research grant 2019 which is contract no.2839/UN6.D/LT/2019, 2 April 2019.’}, {‘$’: ‘This result is a part of research grant 2019 which is supported by Kemenristek Dikti under contract no.2839/UN6.D/LT/2019, 2 April 2019.’}][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.4028/www.scientific.net/KEM.860.53[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
