Provided is a pouch-type secondary battery that includes an electrode assembly equipped with an electrode tab, an electrode lead connected to the electrode tab, a pouch housing accommodating and sealing the electrode assembly such that the electrode lead is partially exposed, and first and second sealants within the pouch housing. The electrode lead includes a joint portion joined to the electrode tab, a terminal portion exposed to an outside of the pouch housing and a fuse portion between the joint portion and the terminal portion. The fuse portion includes a separating groove and a breaking portion connected to the separating groove for separating the terminal portion from the joint portion. The first sealant and the second sealant have shapes that are different from each other such that, when the pressure inside the secondary battery is increased, a stress applied to the pouch housing causes the breaking portion to break.

Pouch-type secondary battery including electrode lead having electrical current limiting function

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.
