Battery cell having anti-wrinkle member

A battery cell configured to have a structure in which an electrode assembly 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 a 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 inner surfaces of the cell case facing outermost electrodes of the electrode assembly,
• wherein each of the anti-wrinkle member is s sheet type member, and
• wherein each of the anti-wrinkle member has a porous structure in which a plurality of pores is formed in the sheet type member, and
• wherein the porous structure is configured such that each of the pores has a diameter of 0.1 mm to 1 mm.
