Activated carbon is a porous carbon material with developed nano-sized pores and a high specific surface area (> 1,000 m2g À1). Nowadays, the technical term “nanoporous carbon” is very often used to mean “activated carbon,” but the activated carbon should be strictly defined as a porous carbon prepared by an activation process consisting of a gasification reaction to form the developed nano-sized pore structure in the carbon matrix. The activated carbons have been widely utilized as industrial materials, for example, an adsorbent, decolorizing agent, deodorant, and catalyst. The details of the preparation method, pore structure, and applications of activated carbons have been described [1]. The most significant electrochemical application of activated carbons is use as an electrode active material for an electric double-layer capacitor (EDLC). This article reviews the use of activated carbons in an EDLC.
