The first pouch and the second pouch each includes a body portion contacting the electrode assembly, the body portion comprising a back side, a front side opposite the back side, and two side surfaces between the back side and the front side; and a pair of wing portions respectively protruding from the two side surfaces of the body portion. A width of each of the pair of wing portions varies along the longitudinal direction of the electrode assembly such that the width of a central part of each of the pair of wing portions is greater than the width of either end part of each of the pair of wing portions.
