MACROCYCLIC COMPLEX MODIFIED ELECTRODES AND CAPACITORS MADE THEREFROM

摘要

Electrodes (10, 11) 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 electrodes (10, 11) are formed from a metal base and coated with an oxide, nitride or carbide of a transition metal or with a conductive polymer. This coating (13) 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).
