Abstract: Disclosed is a coin type lithium ion capacitor which includes a positive electrode made of an activated carbon based positive active material and a negative electrode opposite to the positive electrode with a first separator interposed therebetween. The negative electrode includes a graphite electrode including a first current collector and a graphite based negative active material coated onto the first current collector; and a lithium metal member opposite to the graphite electrode with a second separator interposed therebetween and including a second current collector and lithium metal coated on the second current collector, in which lithium ions of the lithium metal move from the lithium metal to the positive electrode through the graphite electrode during discharge and are carried in the graphite electrode from the positive electrode during charge.

Abstract: An internal electrode structure for optical capacitor and an optical capacitor including an internal electrode thereof are provided to reduce a resistance of an internal electrode for transmitting electrons of an electrical storage unit by coating noble metal particles on both sides of a comparatively inexpensive metal film having high electric conductivity. Noble metal coating layers(51, 52) are coated on both sides of a metal film of an internal electrode(3). The metal film of the internal electrode is formed with one selected from stainless steel, titanium, aluminum, and copper. An optical electrode(1) and a counter electrode(2) are positioned at a left side and a right side of the internal electrode, respectively. A gap between the optical electrode and the internal electrode is filled with an oxidation-reduction electrolyte. The gap between the optical electrode and the internal electrode is filled with a capacitor electrolyte.
