ABSTRACT:
The present invention relates to a high-voltage electric double layer capacitor (EDLC), and more particularly, to an EDLC in which a surge voltage and an operating voltage are enhanced by improving the structure of a unit cell. The EDLC according to the present invention includes a unit cell having at least three electrodes. According to a preferred embodiment of the present invention, the unit cell has a structure constructed by sequentially laminating a first insulating paper layer with a sheet of insulating paper, a first electrode layer with at least two electrodes, a second insulating paper layer with a sheet of insulating paper, and a second electrode layer with at least one electrode. In accordance with the present invention, the number of electrode-facing surfaces increases, and a surge voltage and an operating voltage increase in proportion to the increased number of the electrode-facing surfaces, resulting in a high energy storage density. Accordingly, the present invention has advantages in that an EDLC with a single cell can be applied to products, an EDLC module can be miniaturized, and there is no need for a protection circuit for maintaining voltage balance on a unit cell basis upon fabrication of the module.
