摘要： The present invention provides a cap assembly of a cylindrical secondary battery, comprising a top cap, a PTC element, and an integrated gasket in which a first gasket covering a safety vent and a second gasket covering a current cut-off member are integrated. The secondary battery comprising the thus-configured cap assembly is advantageous in that conventional dual gasket structures are integrated into a unitary gasket structure to increase contact area between the safety vent and the gasket and thus increase sealing effects. Further, the secondary battery of the present invention is advantageous in that the gasket structure freely varies in accordance with the diameter of the current cut-off member, to thereby increase a short-circuit reaction of the current cut-off member, improve safety, and reduce the number of parts and manufacturing costs.
摘要翻译：本发明提供了一种圆柱形二次电池的盖组件，其包括顶盖，PTC元件和集成垫圈，其中覆盖安全通风口的第一垫圈和覆盖当前切断构件的第二垫圈被一体化。包括如此构造的盖组件的二次电池的优点在于，传统的双垫圈结构集成到一体的衬垫结构中，以增加安全排气口和垫圈之间的接触面积，从而增加密封效果。此外，本发明的二次电池的优点在于，垫片结构根据电流切断构件的直径自由地变化，从而增加了电流切断构件的短路反应，提高了安全性，并减少零件数量和制造成本。
