ACTIVATED CARBON, METHOD FOR PREPARING THE SAME, AND ELECTROCHEMICAL CAPACITOR INCLUDING THE SAME |
摘要 |
Disclosed herein are an 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 method for preparing the activated carbon, and an electrochemical capacitor including the activated carbon, so that, 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, there can be provided a supercapacitor and a lithium ion capacitor, having improved high voltage and lifespan characteristics; and the time for preparing an active material can be significantly shortened and thus the material cost and the process cost can be remarkably reduced. |
