摘要: A battery having an electrode assembly comprising a cathode having a cathode collector coated, partially or entirely, with a cathode active material, an anode having a nano-web layer on both sides of an anode collector coated, partially or entirely, with an anode active material, and a separation membrane interposed between the cathode and the anode; an electrolytic solution; and an exterior material which encapsulates the electrolyte solution and the electrode assembly together. Since the battery has a porous nano-web layer, even if the temperature inside the battery increases to cause shrinkage or melting of the separation membrane, a contact between the cathode and the anode is prevented such that ignition and/or explosion of the battery does not occur, ion exchange is not disturbed such that the battery performance does not deteriorate, and the nano-web layer is not molten or released towards the separation membrane even at high temperatures.

摘要: An air permeable cap for a vehicle may include: a cover part formed in a cylindrical shape with a closed end part, and having a plurality of guide ribs radially formed on an inner circumferential surface thereof; a foam part inserted and installed in the cover part so as to be contacted with the guide ribs, and having a ventilation hole formed on one side thereof; a membrane part installed between the foam part and the cover part, and configured to block a flow of water through the ventilation hole and allow a flow of air through the ventilation hole; and an adhesion retention part coupled in a concave-convex shape to retain an adhesion force between the foam part and the cover part.

摘要: Provided is a cartridge filter using nanofiber composite fiber yarn, the cartridge filter including: a core having a plurality of holes through which a liquid passes; and a filter medium wound around the core to collect an object to be filtered contained in the liquid, wherein the filter medium comprises composite fiber yarn in which a nanofiber web which is produced by accumulating nanofibers produced by an electrospinning method is laminated to a porous nonwoven fabric, to thus provide excellent durability and improved filtration performance.
