Zusammenfassung:The present invention relates to a method for manufacturing the electrode of an EDLC which can easily increase the surface area of a current collector by manufacturing the current collector using a foamed metal as a support, and can increase the electrode energy of the EDLC by easily increasing the surface area of the electrode when the current collector using the foamed metal is applied to an electrode. The method includes a step of forming a current collector; and a step of forming an electrode material layer by applying an electrode material to one surface or the other surface of the current collector when the current collector is formed. The step of forming the current collector includes a step of preparing a foamed metal, and a step of forming a metal layer on the front surface of the foamed metal. In the step of forming the electrode material layer, the electrode material layer is formed by applying the electrode material on the surface of the metal layer to be located on one surface or the other surface of the foamed metal. 본 발명은 발포 금속을 지지체로 하여 집전체를 제조함으로써 집전체의 표면적을 용이하게 증가시킬 수 있으며, 발포 금속을 이용한 집전체를 전극에 적용 시 전극의 표면적을 용이하게 증가시킬 수 있어 EDLC의 에너지 밀도를 개선시킬 수 있는 EDLC의 전극 제조방법에 관한 것으로, 집전체를 형성하는 단계; 및 집전체가 형성되면 집전체의 일면이나 타면에 전극물질을 도포하여 전극물질층을 형성하는 단계를 포함하고, 집전체를 형성하는 단계는 발포 금속을 준비하는 단계와, 발포 금속의 전면에 금속층을 형성하는 단계를 구비하며, 전극물질층을 형성하는 단계에서 전극물질층은 발포 금속의 일면이나 타면에 위치되도록 금속층의 표면에 전극물질을 도포하여 형성되는 것을 특징으로 한다.
