Compound and organic light-emitting diode comprising same

Disclosed herein is a pouch-shaped secondary battery including a battery case, an electrode assembly having a structure in which a positive electrode and a negative electrode are stacked in the state in which a separator is interposed therebetween, an electrode lead having an asymmetrical notch formed in a first surface of the electrode lead, the electrode lead being electrically connected to electrode tabs of the electrode assembly, the asymmetrical notch being configured to induce the rupture of the electrode lead, a lead film attached to the first surface and a second surface of the electrode lead, the lead film adhering the electrode lead to the battery case, the lead film including a first lead film located between the electrode assembly and the asymmetrical notch, and a second lead film located between the asymmetrical notch and a portion of the electrode lead that protrudes out of the battery case.

Pouch-shaped secondary battery comprising electrode lead having asymmetrical notch formed therein

Disclosed herein is a pouch-shaped secondary battery including a pouch-shaped battery case surrounding an electrode assembly, a first electrode lead connected to the electrode assembly and extending to a joint of the battery case, a second electrode lead detachably connected to the first electrode lead and extending out of the battery case, a connection layer coupling the first electrode lead and the second electrode lead to each other, and a sealing layer coupling the battery case to the first electrode lead and the second electrode lead, wherein the first and second electrode leads are configured to be detached from one another in order to secure the safety of a pouch-shaped battery cell when the pouch-shaped battery cell swells due to gas generated in the pouch-shaped battery cell while the pouch-shaped battery cell is in an abnormal state or when the pouch-shaped battery cell is overcharged.

Pouch-shaped secondary battery including electrode lead using conductive polymer

Disclosed herein is a pouch-shaped secondary battery including an electrode assembly in which a positive electrode and a negative electrode are stacked with a separator interposed, an electrode lead electrically connected to electrode tabs of the electrode assembly, a pouch-shaped battery case made of a laminate sheet including an outer coating layer, a metal layer, and an inner sealant layer, and a lead box disposed on a sealed portion of the battery case for receiving the electrode lead. In particular, the electrode lead includes a lower electrode lead, which is electrically connected to the electrode tabs, and an upper electrode lead, a portion of which is coupled to the lower electrode lead.
