Pouch type secondary battery and battery pack including the same

Abstract

A pouch type secondary battery includes an electrode assembly including an electrode tab, a pouch that accommodates the electrode assembly and includes a joint portion formed open at a location corresponding to the electrode tab, and a cap assembly including a metal current collector and a cap plate to which the metal current collector is coupled, and in this case, the pouch includes the joint portion joined to the cap plate while the electrode tab is connected to the metal current collector, and the pouch type secondary battery improves stability through a structure in which an electrode tab is connected to a cap assembly and a joint portion of a pouch is joined to the cap assembly.
