Laser power and scanning speed were optimized, in order to favor the formation of nanostructured LIG electrodes. The analysis is performed by SEM, Raman spectroscopy, cyclic voltammetry and galvanostatic charge-discharge. With these optimized parameters, a parallel-plate supercapacitor is built and specific capacitance measurements are performed. Values up to (48 ± 3)mF/cm−2 for the sqared samples and (2, 72 ± 0.13) mF/cm−2 for the supercapacitor device were obtained5 p.application/pdfengcc-by-nc-nd (c) Rio, 2022http://creativecommons.org/licenses/by-nc-nd/3.0/es/SupercondensadorGrafè induït per làserTreballs de fi de grauSupercapacitorLaser-induced grapheneBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
