ELECTRIC DOUBLE LAYER CAPACITOR

摘要

An electric double layer capacitor comprising electrodes consisting of an active carbon, an electrolytic solution containing an electrolyte, and a separator, wherein the electrolyte is an imidazolinium salt, and wherein the active carbon is one obtained by polymerizing a phenolic compound having at least one hydroxyl in each molecule and an aldehyde compound in the presence of a water base solvent and a basic catalyst to thereby obtain an organic aerogel and carbonizing the organic aerogel.
