摘要： An end cap seal assembly for an electrochemical cell such as an alkaline cell is disclosed. The end cap assembly comprises a convoluted end cap which may also function as a cell terminal and an underlying insulating sealing disk. The insulating sealing disk comprises a central boss and radially extending arm terminating in a downwardly sloped elbow and upwardly sloped peripheral edge. The end cap disk has at least one vent aperture therethrough which faces the ambient environment. The insulating disk has an annular groove in its top or bottom surface, which preferably circumvents the central boss. The base of the groove defines an a rupturable membrane portion of the insulating sealing disk. The rupturable membrane is designed to rupture, preferably when the cell internal gas pressure reaches a level between about 150 and 900 psig (1034 x 10 and 6206 x 10 pascal gage) advantageously, between about 150 and 700 psig (1034 x 10 and 4827 x 10 pascal gage). The seal may be made of nylon, polyamide, polypropylene, sulfonated polyethylene.
摘要翻译：公开了一种用于诸如碱性电池的电化学电池的端盖密封组件。端盖组件包括卷曲的端盖，其也可以用作电池端子和下面的绝缘密封盘。绝缘密封盘包括中心凸台和径向延伸的臂，终止于向下倾斜的弯头和向上倾斜的周边边缘。端盖盘具有穿过其中的至少一个面向周围环境的通气孔。绝缘盘在其顶表面或底表面上具有环形凹槽，其优选地围绕中心凸台。槽的底部限定了绝缘密封盘的可破裂膜部分。破裂膜设计为破裂，优选地当电池内部气体压力有利地达到约150至900psig（1034×10 3和6206×10 3帕斯卡计）之间的水平时，在约150至700psig 1034×10 3和4827×10 3帕斯卡计）。密封件可以由尼龙，聚酰胺，聚丙烯，磺化聚乙烯制成。
