Abstract
A secondary battery case accommodates an electrode assembly having a structure in which electrodes and separators are alternately arranged, and includes a first cup having a recessed shape, a second cup having a recessed shape and provided on one side of the first cup, a first peripheral portion surrounding a perimeter of the first cup when the secondary battery case is unfolded, and a second peripheral portion surrounding a perimeter of the second cup when the secondary battery case is unfolded. The first peripheral portion includes a first cup-corresponding peripheral portion that corresponds to a width of the first cup, and the second peripheral portion includes a second cup-corresponding peripheral portion that corresponds to the second cup. The width of the first cup is greater than a length of the first cup-corresponding peripheral portion thereby reducing if not eliminated a bat-ear otherwise formed during manufacture.
