Electrode for capacitor and electric double layer capacitor having the same

摘要

There are provided an electrode for a capacitor and an electric double layer capacitor having the same. The electrode for a capacitor may include: activated carbon; and 25 to 75 parts by weight of carbon aerogel per 100 parts by weight of the activated carbon. The electrode according to an aspect of the invention has excellent bonding strength between electrode materials and is free of defects such as aggregation and cracking. An electric double layer capacitor having this electrode has high capacitance and low internal resistance.
