  "textContent": "Various embodiments of the present invention relate to a secondary battery. A technical problem to be solved is to provide a secondary battery in which, when a can is compressed in a lateral direction thereof, a bending direction thereof is controlled such that a cap assembly (or a circuit interrupt device (CID)) is bent in an opposite direction of an electrode assembly and an electrical short-circuit phenomenon between the cap assembly and the electrode assembly can be thus prevented. To this end, the present invention provides a secondary battery comprising: a cylindrical can; an electrode assembly received in the cylindrical can; and a cap assembly for sealing the cylindrical can, wherein the cap assembly comprises a cap-down having a notch for inducing bending, which allows the cap assembly to be bent in an opposite direction of the electrode assembly when the cylindrical can is compressed in a direction perpendicular to a longitudinal direction of the cylindrical can.",
