  "textContent": "A secondary battery includes an electrode assembly that includes electrode tabs, a case that accommodates the electrode assembly therein and includes an opening at one end, and a cap assembly sealing the opening in the case and electrically connected to the electrode tab. An insulating plate is positioned between the electrode assembly and the cap assembly in the case and includes a first opening and a plurality of second openings, with the first opening being formed to allow the electrode tab to extend therethrough toward the cap assembly, the plurality of second openings being formed around a center portion of the insulating plate. A horizontal cross-sectional area of at least one second opening of the plurality of second openings gradually decreases in a direction toward the electrode assembly.",
