Disclosed is an electric energy storage device having a large capacity and includes a thin active material layer and a plurality of integrated electrodes. The electric energy storage device comprises at least one electrode group in which a cathode, a separator and an anode are in regular sequence, repeatedly integrated and wound into a plate shape. The electrode group has lead lines collected at a predetermined place for a connection with a terminal. Since the cathode and anode are wound with the insertion of the separator between them, the increase of the number of the lead lines is advantageous. In addition, the lead lines can be preferably formed by cutting each portion of the electrode at once by utilizing an apparatus such as a press, the manufacture of the electric energy storage device having a large capacity is advantageous.

In a safety vent part and an electric energy storage device having the same, the safety vent part includes a plate coupled to the device, a metal sheet and a metal cap. A hole having a step portion is formed through the plate, and is in communication with an interior of the device. The metal cap having an exhaust nozzle corresponding the hole is coupled into the step portion by a tight fit. The metal sheet is disposed between a bottom surface of the step portion and the metal cap. When an internal pressure of the device is higher than a predetermined breaking pressure, the internal pressure of the device breaks the metal sheet. A gas generated abnormally in the device is exhausted through the hole and exhaust nozzle.

A method is provided of manufacturing an electrode for an electric double layer capacitor, including mixing an active material, a conductive material and a binder. In this method, Ketjen Black is used as the conductive material and a fluorosurfactant is an additive for enhancing fluidity of the slurry. Also, an electrode for an electric double layer capacitor and an electric double layer capacitor using the electrode are provided. Use of the electric double layer capacitor increases the amount of the active material, so that the electrical capacitance is increased, thus providing the electric double layer capacitor in which the amount of the conductive material is decreased and the electrical resistance is decreased.

The present invention relates to an apparatus and a method for producing hydrogen gas. The hydrogen gas production apparatus of the present invention comprises a) a dielectric hollow tube, b) a means for maintaining the dielectric hollow tube to a reduced pressure, c) a microwave source that generates a microwave, d) a waveguide coupled to the microwave source that applies the microwave to the dielectric hollow tube, e) a gas supply source that supplies a hydrogen element-containing gas into the dielectric hollow tube, wherein the hydrogen element-containing gas supplied into the dielectric hollow tube undergoes plasma discharge with aid of the microwave from the waveguide and produces reaction products including hydrogen gas through intramolecular bond breakage rather than heat decomposition, by collision of an electron produced by the plasma discharge with the hydrogen element-containing gas, and f) a separator that separates the hydrogen gas from the reaction products. The hydrogen gas production apparatus has a simple constitution and provides small scaled production of the hydrogen gas in a simple and efficient manner.

An electrode material composition for use in manufacturing energy storage device electrodes includes an active material, a conductive material including Ketjen Black, a binder comprising at least one of a polymer emulsion dispersed in water and a water-soluble polymer mixture, and a surfactant. The electrodes are manufactured by thy-mixing the active material and the conductive material to form a thy-mixed active material mixture. The drymixed active material mixture is then mixed with a binder solution to form a slurry and the slurry is coated onto a currently collector and dried to form an electrode.
