Abstract

Aspects of embodiments of the present disclosure relate to pouch-type secondary batteries (100), press devices (150) for secondary batteries (100), and manufacturing methods (180) of secondary batteries (100). A pouch-type secondary battery (100) includes: an electrode assembly (110) including a stack of unit cells (112) including: a first electrode plate (114); a first electrode tab (116) on the first electrode plate (114); a second electrode plate (120); a second electrode tab (122) on the second electrode plate (120); and a separator (118) between the first electrode plate (114) and the second electrode plate (120); and a first tape (130, 132) attached to a front side of the electrode assembly (110) perpendicular to a stacking direction of the stack of unit cells (112). The first tape (130, 132) is located at a corner portion (138) of the electrode assembly (110) where the first electrode tab (116) or the second electrode tab (122) is located, and the corner portion (138) is located at an inclined area (128, A, A') where a thickness of the electrode assembly (110) decreases.
