Highly graphitized carbonaceous thin films prepared by plasma-assisted chemical vapor deposition were surface-modified by electropolymerization of pyrrole. The electrochemical properties of the films were studied by cyclic voltammetry and AC impedance spectroscopy. Irreversible cathodic current above 0.6V vs. Li/Li⁺ was significantly decreased in the cyclic voltammograms, indicating that the surface modification of carbonaceous materials by electropolymerization should be effective for decrease in irreversible capacities in lithium-ion batteries.
