Abstract

A pouch-type secondary battery includes an electrode assembly, in which a plurality of positive electrodes and a plurality of negative electrodes are alternately stacked with separators therebetween, and a pouch which is formed by sealing a pair of cases integrally connected to each other by a folding portion and includes an accommodation portion that accommodates the electrode assembly. A plurality of outer walls forming a perimeter of the accommodation portion may include a folding portion-side outer wall, which includes the folding portion, and a sealing portion-side outer wall which is connected to a sealing portion in which the pair of cases are fused to each other. An average distance between ends of the plurality of negative electrodes and the folding portion-side outer wall may be about 0.6 mm or less.
