    Abstract: Disclosed is a technology for preventing electrodes in a secondary battery from being short-circuited with each other. An electrode assembly includes a cathode and anode of which a cathode collector and anode collector are coated with a cathode active material and anode active material, respectively, and a separator disposed between the cathode and the anode. An insulation layer is disposed on a tab part of the cathode collector constituting the cathode. Thus, an insulation layer may be disposed on an end (a tab part) of the cathode collector that is used as a tab of the cathode electrode in the structure of the electrode assembly to prevent the cathode from being physically short-circuited with the anode in the sequentially stacked structure of cathode/separator/anode.

    Abstract: Provided is a cathode including a cathode current collector, a cathode tab protruding from the cathode current collector, and an insulation layer coated with an insulating material on the cathode tab, and a secondary battery including the cathode. Since the cathode of the present invention includes an insulation layer on a cathode tab, the present invention may prevent an internal short circuit which may occur due to cell deformation or sharp edges of electrodes, which are formed during cutting of the electrodes in a preparation process of the battery, when the electrodes are stacked, or may prevent a physical short circuit between the cathode and the anode due to shrinkage of a separator in a high-temperature atmosphere. In a case where the cathode is used in a lithium secondary battery, safety and reliability in battery performance may be significantly improved.
