Method for pretreating electrochemical capacitor negative electrode, method for manufacturing the electrochemical capacitor negative electrode, and method for manufacturing electrochemical capacitor using the method for manufacturing the electrochemical capacitor negative electrode

摘要

A negative electrode of an electrochemical capacitor includes an electrode layer using a material capable of reversibly absorbing and releasing a lithium ion. A method for pretreating the negative electrode includes forming a lithium layer on a substrate by a gas phase method or a liquid phase method, and transferring the lithium layer onto a surface of the electrode layer of the negative electrode.
