MANUFACTURING METHOD OF CARBON ELECTRODE THROUGH ELECTROCHEMICALLY ACTIVATED AND CARBON ELECTRODE THEREOF AND REDOX FLOW BATTERY MANUFACTURED THEREBY

摘要

PURPOSE: A method for manufacturing a carbon electrode through electrochemical activation is provided to rapidly activate a carbon electrode, to increase an oxygen functional group of the carbon electrode, to improve the capacity and efficiency of the redox flow battery, and to reduce the resistance of an electrode. CONSTITUTION: A method for manufacturing a carbon electrode(30) through electrochemical activation comprises the steps of: filling a mixed solution of distilled water and acid in a cell electrode part in which a unit cell or a stack is assembled; and electrochemically activating the electrode part. The mixed solution is a solution of 0.1~10 M molarity in which one or two or more from the group consisting of sulfuric acids, nitric acids, and phosphoric acids are mixed.
