Electrode Assembly And Electrochemical Device Including Same
Abstract: The present invention relates to a technique for preventing a short circuit of an electrode in a secondary battery and particularly can provide an electrode assembly comprising: a cathode and an anode between which is placed a separation film and having active materials coated on current collectors; the separation film arranged between the cathode and the anode; and an insulating layer formed at a tap part of a cathode current collector constituting the cathode. According to the present invention the physical short circuit of the cathode and the anode can be prevented in a sequential lamination structure of cathode/separator/anode by forming the insulating layer at an end part (tap part) of the current collector used as the tap of the cathode in the structure of the electrode assembly.
