    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.
