Surface modification method of the carbon material electrode by conducting of joule-heating a surface-modified carbon electrode thereof and electrochemical capacitors comprising the surface-modified material electrode

摘要

The present invention relates to an electrochemical capacitor including a carbon material electrode surface modification method by energization, a surface modified carbon material electrode and a surface modified carbon material electrode, comprising the steps of: preparing a carbon material electrode; binding a conducting terminal to the carbon material electrode; It is a technical gist to include the step of generating Joule's heat by applying an electric current to the conducting terminal so that an acid functional group or adsorbed water present in the carbon material electrode is removed. Thereby, by directly applying electricity to the carbon material electrode manufactured including the carbon material, the functional group or adsorbed water present in the carbon material pores of the carbon material electrode can be removed within a short time by Joule's heat.
