Supercapacitors exhibit a larger capacitance than other energy storage devices, and their charge-discharge performance can be maintained at a high level through repeated charge-discharge cycles. In this study, we fabricated conductive structures composed of graphitic carbon on biodegradable composite sheets by laser-induced carbonization and applied the fabricated structures to the electrodes of the supercapacitor. The obtained cyclic voltammetry curve showed charge-discharge characteristics.
