Аннотация:This work reports, for the first time, the conversion of polyethylene oxide (PEO) into porous carbon (PC) and its application for supercapacitor (SC). In contemporary technology applications, porous carbon (PC) and related materials are vigorous in nature. Due to the irreplaceable unique characteristics of PC, like tunable pore volume and pore size, physical and chemical stability, and very high surface area, its applications are considered in a broader range. Along with these, a good catalytic properties and low cost make it a better choice as an electrode material for SC. Therefore, this work comprised the synthesis of PC from PEO by using concentrated sulfuric acid (con. H2SO4) as activating agent. Detailed studies related to the synthesized PC were conducted, and its potential applications were thoroughly investigated in SC. The fabricated SC cell showed thehighest specific capacitance of ~ 100 F/g at 5 mV/S with Ionic liquid (EMImTCM) incorporated PVDF-HFP solid polymer electrolyte. Therefore, this study not only advances our understanding of PEO as a new precursor for synthesis of PC, but also offers tangible insights to propel progress towards a more sustainable and efficient energy future.
