Abstract
A method for producing a carbon electrode which includes directly depositing a carbon material on an electroconductive electrode substrate by chemical vapor deposition using hydrocarbons and/or their derivatives as a starting material, and subjecting the substrate coated with the carbon material to an electrochemical treatment so that the carbon material is doped with a charge carrier material capable of being reversely intercalated therein and deintercalated therefrom. Thereafter, the electrochemically treated substrate is compressed, and a thin plate-shaped carbon electrode with a high density results.
