Abstract
Disclosed herein is a battery cell configured to have a structure in which an electrode assembly, including positive electrodes and negative electrodes stacked in the state in which separators are disposed respectively between the positive electrodes and the negative electrodes, is mounted in a cell case in the state in which the electrode assembly is impregnated with an electrolyte, wherein the electrode assembly and the cell case are deformable in response to the shape of a device in which the battery cell is mounted, and anti-wrinkle members, for preventing wrinkles from being formed in the cell case when the cell case is deformed, are added to at least portions of the outer surfaces of the electrode assembly.
