Abstract:
A process for producing activated carbon for an electrode of an electric double-layer capacitor, comprising the steps of:subjecting a carbon material to a carbonizing treatment; and then subjecting the carbon material to an alkali activating treatment; wherein the carbon material used is a condensed polycyclic aromatic compound which has a condensed ring and at least one aliphatic hydrocarbon radical bonded to said condensed ring, said condensed ring including at least one alicyclic hydrocarbon structure moiety; and wherein, in an analysis chart resulting from a 13C-NMR spectroscopy of the condensed polycyclic aromatic compound, a signal intensity ratio IL/IR is equal to or larger than 0.2, and a signal intensity ratio IC/IR is equal to or larger than 0.14, wherein IR represents a signal intensity of an aromatic peak; IL represents a signal intensity of an aliphatic hydrocarbon peak; and IC represents a signal intensity of an alicyclic hydrocarbon peak.
