用于电化学电池的端帽组件
摘要：
本发明公开了一种用于电化学电池(10)的端帽组件(26)，该端帽组件(26)具有端帽(24)、集流体(20)、和密封件(22)。集流体(20)包括在其一个端部处具有头部(34)的柱状主体(32)。密封件(22)具有中心毂(36)，该中心毂(36)具有集流体(20)插入穿过其中的开口(38)。密封件(22)还具有周边边缘(40)和连接中心毂(36)与周边边缘(40)的连接部分(42)。中心毂(36)的顶部表面(48)面向端帽(24)的底部表面(50)并且中心毂(36)的底部表面(50)不在连接部分(42)的底部表面(46)下方延伸。集流体(20)定位在中心毂(36)的开口(38)内，使得集流体(20)的头部(34)不接触中心毂(36)的顶部表面(48)，从而在集流体(20)的头部(34)和中心毂(36)的顶部表面(48)之间形成0.01mm至0.50mm的间隙。集流体(20)的头部(34)电连接到端帽(24)的底部表面(30)。
摘要（英）：

The invention discloses an end cap assembly (26) for an electrochemical cell (10) having an end cap (24), a current collector (20), and a seal (22). The current collector (20) has a columnar body (32) with a head (34) at one end thereof. The seal (22) has a central boss (36) with an opening (38) through which the current collector (20) is inserted. The seal (22) also has a peripheral edge (40) and a connecting part (42) connecting the central boss (36) with the peripheral edge (40). The top surface (48) of the central boss (36) faces the bottom surface (50) of the end cap (24) and the bottom surface (50) of the central boss (36) does not extend below the bottom surface (46) of the connecting part (42). The current collector (20) is positioned within the opening (38) of the central boss (36) so that the head (34) of the current collector (20) does not touch the top surface (48) of the central boss (36), thus forming a gap from 0.01 mm to 0.50 mm between the head (34) of the current collector (20) and the top surface (48) of the central boss (36). The head (34) of the current collector (20) is electrically connected to the bottom surface (30) of the end cap (24).
