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.
