  • Publication number: 20120042490
    Abstract: The present invention provides a method of pre-doping lithium ions into an electrode, and a method of manufacturing an electrochemical capacitor using the same. The method for pre-doping lithium ions into an electrode includes the steps of: immersing a positive electrode, a negative electrode, and a lithium metal electrode into an electrolyte solution; performing a first pre-doping for directly doping lithium ions into the negative electrode from the lithium metal electrode; and performing a second pre-doping which includes a charging process for applying currents between the positive electrode and the negative electrode to charged with the applied currents, and a releasing process for releasing lithium ions from the lithium metal electrode, and a method for manufacturing the electrochemical capacitor using the same.
