    摘要： The present disclosure relates to a secondary battery having improved safety. The present disclosure provides a pouch type secondary battery which includes an electrode assembly and a pouch sheath material including a first pouch portion and a second pouch portion. The pouch-type secondary battery includes dual electrode leads wherein a first electrode lead is attached to the first pouch portion and a second electrode lead is attached to the second pouch portion. In the pouch-type secondary battery, electric current is interrupted by using a volumetric swelling phenomenon caused by swelling or pressure generated upon overcharge so that the battery may be prevented from being further charged. In addition, when pressure is increased by an additional reaction, venting occurs toward the inner lead portion of each of the dual electrode leads. As a result, it is possible to increase the stability of a battery cell, module and a pack received in the pouch, and thus to improve the life of a battery.

    摘要： A secondary battery includes an electrode assembly having an electrode tab; an electrode lead attached to the electrode tab and having at least one lead hole; a pouch case for accommodating the electrode assembly so that the electrode lead is drawn out; and a sealing tape interposed between the electrode lead and the inner surface of the pouch case and having a venting pattern portion formed at a region corresponding to the lead hole. Therefore, when gas is generated inside a pouch case of a secondary battery due to an abnormal circumstance, for example when an overcurrent flows at the secondary battery since a protective circuit does not operate normally, a sealed state of the pouch case is rapidly released, thereby ensuring the safety of the secondary battery in use.
