Abstract

We Demonstrated and Verified the Use Of laser Reduced Graphene Oxide (LRGO) Supported on Polyethylene Terephthalate (PET) Substrate for Flexible Supercapacitor Applications. we Compared the Interdigitated in-Plan Structure with the Conventionally Stacked Structure Supercapacitor. To understand the Role of Increasing the Number of Sub-Electrodes per Unit Area, Three electrode Architecture of 2, 4, and 6 Sub-Electrodes were Studied. Polymeric Gel electrolyte of Poly (vinyl Alcohol) and Phosphoric Acid (PVA-H3PO4)was Selected for the Realization of the Cells. the Interdigital in – Planesupercapacitor with 6 Sub-Electrodes I-PS(6) Showed a Volumetric Capacitance Of9.3 Fcm-3 Opposed to 3.6, 0.6, 0.5 Fcm-3 for I-PS(4), I-PS(2), and conventional Structure Supercapacitor, Respectively at 0.1 Ma Cm-2 Current Density. the Maximum Stated Energy Density of 0.409 Mwh.cm-3and Power Density of 994.6 W.cm-3 were for I-PS(6). our Results clearly Showed that the LRGO can Hold much Promise for Low-Cost, Easy, and Scalablesupercapacitor Fabrication.
