摘要： The present disclosure provides an electrode lead that ensures safety of a secondary battery when gas is generated within the secondary battery. The electrode lead is included in a pouch-type secondary battery in which outer circumferential parts of a pouch casing are sealed and an electrode assembly is accommodated in a center part of the pouch casing. The electrode lead includes an inner lead at least partially formed of an electrically-conductive material, contacting an electrode tab of the electrode assembly, and interposed between the sealing parts of the pouch casing; and an outer lead disposed outside of the inner lead, at least partially formed of an electrically-conductive material, providing an external terminal connectable to an external device, interposed between the sealing parts of the pouch casing, and configured such that a portion of the outer lead contacts the inner lead and that, when an inner pressure of the pouch-type secondary battery increases, the outer lead is partially deformed and thus the portion of the outer lead is detached from the inner lead.
