Abstract
With increasing the concern to clean energy device, such as electric vehicle (EV), electric double layer capacitor (EDLC) is considered as an indispensable to recover the uneven load level required for practical operation in diverse applications when compared with other energy sources. The development of EDLCs has deep relation to the carbon materials with highly porous structure (>1000m2/g). Until now, contributions of carbon science to elucidating the relation between electrode and electrolyte have been enormous, and further achievement of future scientific studies on new forms of carbons, such as activated carbon, could afford even larger success in the development of EDLC. In this review, we depict the various parameters related to EDLC performance, on the basis of our research results. In particular, the size effect of the electrolyte ion, the morphological effects of active materials, are discussed.
