Abstract
(EN)
A pouch-type battery case according to an embodiment of the present invention for solving the problem is a pouch-type battery case that accommodates therein an electrode assembly in which an electrode and a separator are stacked, and comprises: a first cup part and a second cup part, which are arranged side by side in a pouch film and recessed; and a bridge which is formed between the first cup part and the second cup part and has a constant width and height. The first cup part includes: a first outer wall formed facing away from the bridge; a second outer wall formed facing the bridge; and a first bottom portion connecting the first outer wall and the second outer wall. The second cup part includes: a third outer wall formed facing the bridge; a fourth outer wall formed facing away from the bridge; and a second bottom portion connecting the third outer wall and the fourth outer wall, wherein the fourth outer wall is higher than the first outer wall.
