ABSTRACT:
Electrodes for electrochemical capacitor are modified with a metal macrocyclic complex made up of phthalocyanine or porphyrin ligands bound to a transition metal to achieve improved conductivity, reversibility, and charge storage capacity. The electrode is formed from a metal base and coated with an oxide, nitride or carbide of a transition metal or with a conductive polymer. This coating is modified with the metal macrocyclic complex. Suitable metal macrocyclic complexes are iron phthalocyanine (FePc), iron meso-tetra(N-methyl-4-phenyl)porphyrin (FeTPP) or cobalt protoporphyrin (CoPP).
