Pouch-type secondary battery with a groove in the sealing part |
| abstract |
The battery cell according to the present invention is a battery cell in which an electrode assembly having a positive electrode / separation membrane / negative electrode structure is sealed together with an electrolyte in an electrode assembly housing portion of a pouch-type battery case, An electrode assembly and a sealing part that is heat-sealed to the outer peripheral surface in a state where the electrolytic solution is incorporated are formed, and the electrode can be prevented from being wrinkled in the sealing part of the battery case when the battery cell is bent. The side sealing portions on both sides adjacent to the upper end sealing portion and / or the lower end sealing portion where the terminals are located have one or more grooving grooves formed in the direction from the end of the side sealing portion to the vertical center axis of the battery cell. And providing a battery cell characterized in that the region of the side sealing portion where the bay groove is located is sealed at a relatively higher sealing temperature than the remaining region of the side sealing portion. |
