<p>The present invention relates to activated carbon in which pores with pore sizes of 0.3-5 nm account for 80% or higher based on an overall pore volume, a manufacturing method thereof, and an electrochemical capacitor including the activated carbon as an electrode active material. According to the present invention, since the activated carbon has uniform-sized fine pores, high-rate discharge characteristics, high-rate charging and discharging characteristics, and low-temperature characteristics can be improved. Since the content of functional groups on the surface of the activated carbon is low, the present invention provides a supercapacitor and lithium ion capacitor with high voltage and improved lifetime property. Moreover, the time for manufacturing an active material can be significantly shortened and thus material costs and process costs can be remarkably reduced.</p> |
