    • A cap assembly and a secondary battery having the same which can prevent current from flowing out of the battery by preventing contact of a broken vent member with a cap. The vent member is broken due to an internal pressure of the secondary battery greater than a predetermined level. The cap assembly includes a vent member having a plurality of notches formed in a radial direction from the center of the vent member and a plurality of reinforcement parts formed between the notches. The cap assembly may include a vent member having a plurality of notches formed between two adjacent notches so that the vent member folds when the internal pressure of the secondary battery is too great.
    • 具有该盖组件和二次电池的盖组件和二次电池可以防止电流从电池中流出而防止通气部件与盖子接触。 排气构件由于二次电池的内部压力大于预定水平而破裂。 所述盖组件包括排气构件,所述排气构件具有从所述排气构件的中心沿径向形成的多个切口以及形成在所述凹口之间的多个加强部。 盖组件可以包括具有形成在两个相邻凹口之间的多个凹口的排气构件,使得当二次电池的内部压力太大时,排气构件折叠。

    • Disclosed is a rechargeable battery that can improve sealing performance of a gasket and prevent a cap assembly from rotating with respect to a case. The rechargeable battery includes an electrode assembly that includes an anode, a cathode, and a separator interposed between the anode and the cathode, a case that accommodates the electrode assembly, a cap assembly that is coupled with the case to close and seal the case and that has an electrode terminal, and a gasket that is provided between the cap assembly and the case. A protrusion is formed at a surface of the gasket. A ratio of a height of the protrusion to a half-width of the protrusion is about 0.5 to 0.8.
    • 公开了可充电电池,其可以改善垫圈的密封性能并防止盖组件相对于壳体旋转。 可再充电电池包括电极组件,其包括阳极,阴极和置于阳极和阴极之间的隔膜,容纳电极组件的壳体,与壳体联接以关闭和密封壳体的盖组件,以及 其具有电极端子,以及设置在盖组件和壳体之间的垫圈。 在垫圈的表面形成突起。 突起的高度与突起的半宽度的比率为约0.5〜0.8。
