Abstract
Official abstract text for this publication.
A pouch-type secondary battery includes: an electrode assembly including a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode; and a pouch case including a sealing portion sealed along an edge thereof to accommodate the electrode assembly therein, and a terrace portion formed to extend toward the sealing portion in which an electrode lead is disposed, wherein a notch portion at which a body of a perforator is seated is formed in the sealing portion to form a perforation portion on the terrace portion.
First claim
Opening claim text (preview).
What is claimed is: 1. A pouch-type secondary battery, comprising: an electrode assembly including a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode; and a pouch case including a sealing portion sealed along an edge thereof to accommodate the electrode assembly therein, and a terrace portion formed to extend toward the sealing portion in which an electrode lead is disposed, wherein a notch portion is formed to be spaced apart from one surface of the sealing portion adjacent to the notch portion in a longitudinal direction of the pouch-type secondary battery in the sealing portion. 2. The pouch-type secondary battery of claim 1 , wherein the notch portion is formed at an edge of the sealing portion on a side from which an electrode lead protrudes. 3. The pouch-type secondary battery of claim 1 , wherein the notch portion is formed in the sealing portion between the positive electrode lead and the negative electrode lead. 4. The pouch-type secondary battery of claim 1 , wherein two or more notch portions are formed. 5. The pouch-type secondary battery of claim 1 , wherein the notch portion has one surface which is opened. 6. The pouch-type secondary battery of claim 1 , wherein the pouch case is a single unit of sheet-type pouch case used for packaging the electrode assembly.
