Pouch for Secondary Battery Formed of Multiple Pouches, and Secondary Battery Including the Same

Abstract

A secondary battery may include: an electrode assembly in which an electrode and a separator are alternately stacked; a plurality of pouches that surrounds the electrode assembly and seals the electrode assembly; and a spring part that is coupled to the outermost pouch of the plurality of pouches and provides a degree of structural rigidity of the outermost pouch. Additionally, a secondary battery may include: an electrode assembly in which an electrode and a separator are alternately stacked; a plurality of pouches that surrounds the electrode assembly and seals the electrode assembly; an open portion formed at one side of the outermost pouch of the plurality of pouches and passing through a portion of the one side; and a spring part that is coupled to both ends of the open portion and provides a degree of structural rigidity of the outermost pouch.
