A method for determining an available power of a wind farm, wherein the wind farm comprises a plurality of wind power installations with a rotor having rotor blades, the blade angle of which can be adjusted is provided. A wind farm which is set up to carry out the method for determining an available power is provided. The method comprises providing a shading matrix which determines at least one effective wind speed of each of the wind power installations in the wind farm as a function of at least one wind speed and wind direction and wind farm throttling using a park wake model. The method makes it possible to accurately determine an available power of a wind farm even when the wind farm is operated with throttled power.

The present invention provide a pouch type secondary battery and a method for manufacturing the same. More particularly, the present invention provides a pouch type secondary battery and a method for manufacturing the same, in which a pouch case is formed in a folding manner without being subjected to a forming process (press process), such that there is no limit in a length, and a thickness of an inner space of the pouch case is not limited.

To solve the above problem, a pouch forming apparatus according to an embodiment of the present invention includes: a die in which a forming space is recessed inward from a top surface thereof; a partition wall partitioning the forming space into first and second forming spaces; a stripper disposed above the die and configured to descend to contact the die with the pouch film therebetween to fix the pouch film to be seated on a top surface of the die; and an electromagnetic force generation part disposed above the forming space and configured to generate electromagnetic force and configured to apply the electromagnetic force to the forming space.

The present invention relates to an electrode rolling roll cleaning apparatus for removing pollutants on an electrode rolling roll, the apparatus comprising: a cleaning part for cleaning a rolling roll by bringing the rolling roll into contact with a cleaning member; an air spraying part for spraying air onto the rolling roll; a heating part for applying heat to the rolling roll so as to dry the rolling roll; and a scraper part for mechanically removing a cleaning liquid and foreign substances attached to the rolling roll.

A purpose of the present invention is to provide a lithium ion secondary battery having improved battery characteristics. The lithium ion secondary battery according to the present invention comprises a negative electrode comprising a negative electrode active material comprising a silicon material and an electrolyte solution comprising an electrolyte solvent comprising an open chain sulfone compound, a fluorinated cyclic carbonate and an open chain carbonate and a supporting salt comprising LiN(FSO.sub.2).sub.2.

Disclosed are a polymer electrolyte membrane for a fuel cell, a membrane-electrode assembly including the same, a fuel cell and a method of manufacturing the polymer electrolyte membrane for a fuel cell. Particularly, the polymer electrolyte membrane for a fuel cell may include ionomer layers including a voltage reversal tolerance-increasing additive including a water electrolysis catalyst and an electrical conductor and provided on a porous reinforced film.

A carbon dioxide production system 10A includes: a fuel cell stack 16; a separation unit 20 that separates anode off-gas into a non-fuel gas including at least carbon dioxide and water and a regenerative fuel gas; a second heat exchanger 32 that separates water from the non-fuel gas; a water tank 42; and a carbon dioxide recovery tank 48 that recovers the carbon dioxide after the water has been separated.

A heat radiation member for a flexible display having a bending panel fixing member is disclosed, and an electronic device using the same is disclosed, wherein the heat radiation member includes a heat radiation sheet portion including a metal layer; a bending panel fixing member attached to a first area in one surface of the heat radiation sheet portion; a spacer attached to a second area in the one surface of the heat radiation sheet portion; a dummy double sided tape attached to the spacer; an upper delamination film covering an entire area of the other surface of the heat radiation sheet portion; and a lower delamination film covering an entire area of the dummy double sided tape and an entire area of the bending panel fixing member.

Disclosed is an anodeless-type all-solid-state battery. The all-solid-state battery includes a plurality of recesses formed in an electrolyte layer and to be depressed from a surface of the electrolyte layer contacting an anode collector and thus serve as spaces for lithium to reversibly precipitate.

A display panel includes a light-emitting device on a substrate and an encapsulation structure on a light output surface on one side of the light-emitting device. The encapsulation structure includes a first inorganic layer and a fluoro-polymeric layer. Ductility and bending resistance of the fluoro-polymeric layer are greater than those of the first inorganic layer. Defects between the fluoro-polymeric layer and the first inorganic layer are fewer than those between the first inorganic layer and another layer.
