ACTIVATED CARBON FOR ELECTRIC DOUBLE LAYER CAPACITOR BY CO2-ALKALI COMPLEX ACTIVATION PROCESS AND METHOD FOR MANUFACTURING THE SAME

摘要

The present invention relates to activated carbon for an electric double layer capacitor through activation _{of a CO 2 -alkali complex and a method for manufacturing the same.} The present invention provides an activated carbon _{for an electric double layer capacitor in which alkali activation and CO 2} activation are simultaneously performed by activating a carbon material mixed with an alkali activator at a temperature of 900° C. or higher under a _{CO 2} atmosphere, and a method for manufacturing the same. According to the present invention, micropores and mesopores are developed at the same time by _{CO 2} -alkali complex activation, which simultaneously proceeds alkali activation (chemical activation) and CO ₂ activation (physical activation) It is possible to improve the electrical characteristics of the double layer capacitor.
