SECONDARY BATTERY, COMPONENT FOR THE SAME AND METHOD FOR MANUFACTURING THE SAME |
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. |
