There is provided an electric double layer capacitor and a method of manufacturing the same. The electric double layer capacitor includes first and second electrodes facing each other; and an ion-permeable separator interleaved between the first and second electrodes, wherein at least one of the first and second electrodes includes a metallic fiber being compressed to have pores therein and an electrode material filling the pores. The electric double layer capacitor has low equivalent series resistance (ESR) and high output density. Also, since the electrodes are formed to be thin, the electric double layer capacitor can be miniaturized.

There is provided an electric double layer capacitor including: a multilayer electric double layer capacitor cell including first and second electrodes facing each other with an ion-permeable separator interposed therebetween; and an insulating tape with which to enclose an outer surface of the multilayer electric double layer capacitor cell and having a plurality of pores. In the electric double layer capacitor, movements between the first and second electrodes and the ion-permeable separator are minimized so that the area of the facing surfaces of the first and second electrodes increases. Accordingly, high capacitance may be achieved. In addition, the pores formed in the insulating tape facilitate the path of an electrolyte so that the impregnation of the electrolyte into the multilayer electric double layer capacitor cell is thereby facilitated.

There is provided a chip-type electric double layer capacitor cell and a method of manufacturing the same. The chip-type electric double layer capacitor cell includes a separator folded to include first and second folded portions with first and second open portions formed in opposite directions by the first and second folded portions, and first and second electrodes inserted into the first and second open portions. The positions of the first and second electrodes are fixed by the first and second folded portions of the separator, and accordingly, the appropriate arrangement of the plurality of first and second electrodes is facilitated. A short circuit between the first and second electrodes is avoided to thereby increase the capacitance of the chip-type electric double layer capacitor cell.

A self-magnetized motor includes a stator adapted to rotate by electromagnetic interaction with a rotator, a plurality of slot teeth formed on and surrounding a through-hole of the stator, and an excitation pole adjacent at least one slot tooth having fewer projections than remaining ones of the slot teeth. The projections are formed on ends of the slot teeth facing the through-hole of the stator. According to one non-limiting embodiment, the excitation pole may be formed between two slot teeth having fewer projections.
