Fabrication of ZnO – Carbonized cotton yarn derived hierarchical porous active carbon flexible electrodes

This work mainly focuses on the development of a novel type chemically activated electrodes from cotton yarn by carbonization and chemical activation. Chemical activation is employed in order to obtain high specific capacitance, energy power density. The zinc oxide was prepared sol – gel method pH should be range 9 11. ZnO/CCY electrode it stirred with magnetic stirrer. performance evaluated using aqueous electrolyte at various current densities scan rate. sample which electrochemically characterized CV, GCD EIS. paper reports highly flexible, less weight, electrically conductive an electrochemical capacitance 10.06 F g−1 150 mV s−1. ZnO powders were evenly developed over carbonized yarn. porous nanostructure presented powder enough potential electro-active sites. Additionally, offered good adsorption. well-developed fiber showed enhanced stability analysis From results, fabricated flexible can provide impending applications cable-type devices next generation supercapacitors.
