Abstract
The present invention relates to an electric double-layer capacitor and a method for producing same capable of evenly and rapidly doping a negative electrode layer with lithium ions. The electric double-layer capacitor comprises: a positive electrode including a positive electrode layer formed on one surface of a positive electrode current collector; a negative electrode including a negative electrode layer formed on one surface of a negative electrode current collector; a first separator disposed between the positive electrode layer and the negative electrode layer; and a second separator disposed between the positive electrode current collector and the negative electrode current collector, in which the negative electrode includes holes penetrating through the negative electrode current collector and reaching the negative electrode layer.
