Sol-gel synthesized carbon nanoparticles as supercapacitor electrodes with ultralong biking stability: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 29, No 12

Summary

Just lately, high-performance power storage units are urgently wanted because of the fast growth of miniaturized, moveable and excessive efficiency digital gear. On this work, we current a facile sol-gel method adopted by electrochemical deposition for synthesizing carbon nanoparticles electrode that displays the potential for use as each constructive in addition to damaging supercapacitor materials. The method used right here for the synthesis of carbon nanoparticles electrode leads to pseudocapacitive conduct as an alternative of typical EDLC. Additional, the synthesized carbon nanoparticles electrode displays particular capacitance of 73.75 F/g at 0.001 A in potential vary of −0.4 to 0.4 V together with wonderful cyclic stability even after 9000 GCD cycles. Within the constructive potential window i.e., from 0 to 0.4 V, the synthesized CNPs electrode displays good particular capacitance worth of 177.75 F/g at 0.001 A whereas within the damaging potential window i.e., from −0.6 to 0 V, it reveals particular capacitance of 88 F/g at 0.001 A. These outcomes point out that the synthesized carbon nanoparticles electrode is a promising materials for supercapacitor purposes.
