Abstract:
1. An electric double layer capacitor (EDLC) comprising: an electric double layer cell comprising a separator and at least one first polarizable electrode and at least one second polarizable electrode which are alternatively stacked with the separator interposed therebetween; and first and second external electrodes formed at first and second side surfaces of the electric double layer cell facing each other, respectively, wherein the first polarizable electrode comprises a first current collection layer and a first active material layer formed on either surface of the first current collection layer facing the separator, extends to the first side surface of the electric double layer cell so as to be connected to the first external electrode, and is electrically separated from the second side surface so as to be insulated from the second external electrode, and the second polarizable electrode comprises a second current collection layer and a second active material layer formed on either surface of the second current collection layer facing the separator, extends to the second side surface of the electric double layer so as to be connected to the second external electrode, and is electrically separated from the second side surface so as to be insulated from the first external electrode.
