  "textContent": "A jelly-roll electrode assembly may include a first separator, a negative electrode, a second separator, and a positive electrode, which are sequentially laminated and wound. A core portion of the jelly-roll electrode assembly includes a rigid film disposed between the first separator and the second separator. A length of the rigid film in a longitudinal direction may be from 100% to 150% of an inner circumference of the jelly-roll electrode assembly and a tensile strength of the rigid film may be from 18 kgf/mmto 25 kgf/mm. A secondary batter may include the jelly-roll electrode assembly, and the jelly-roll electrode assembly may be manufactured by a method described herein.",
