제목 Enhanced electrochemical properties of activated carbon by E-beam irradiation
초록 Activated carbons (ACs) were modified via e-beam irradiation at various doses for use as an electrode material in electric double layer capacitors (EDLCs). The ACs treated with the e-beam at radiation doses of 200 kGy exhibited higher nano-crystallinity than the untreated ACs. The specific surface areas and pore volumes of the e-beam irradiated ACs were also higher than those of the untreated ACs. These results were attributed to the transformation and degradation of the nano-crystallinity of the AC surfaces due to the e-beam irradiation. The specific capacitance of the AC increased by 24% after e-beam irradiation. The enhancement of the electrochemical properties of the e-beam irradiated ACs can be attributed to an increase in their specific surface area and surface crystallinity.
