Activated carbon/carbon composite electrode suitable as a polarizable electrode for use in an electric double-layer capacitor and method of producing the same

摘要

A polarizable electrode (1) comprises an activated carbon/carbon composite cosisting essentially of an activated carbon component and a carbon component. The activated carbon component comprises activated carbon powder or fiber. The carbon component is produced by carbonizing a thermosetting resin. The composite has a density within a range between 0.70 and 0.85 g/cm3, both inclusive, and a thickness within another range between 0.7 and 3.0 cm, both inclusive.
