Abstract: An electrochemical cell is provided that includes a container, a cathode and anode disposed in the container, and a separator disposed between the anode and cathode. The cell further includes an extender either included in or separate from the cathode. An agent is further provided that interacts with soluble ionic species generated in the cathode to prevent the migration of the species to the anode.

Abstract: A current interrupt mechanism for electrochemical cells is disclosed. A thermally activated current interrupt mechanism (38) is integrated into an end cap assembly (10) for an electrochemical cell. The thermally responsive mechanism preferably includes a free floating bimetallic disk (40) or a meltable mass of material (175) to break an electrical pathway within the end cap assembly. The end cap assembly also includes integrated therein a pressure responsive current interrupt mechanism (48). The pressure responsive mechanism activates to sever electrical contact between a diaphragm (70) and a plate (80) within the end cap assembly (10) to prevent current from passing through the cell, and may include a diaphragm (70) which ruptures when there is extreme gas pressure buildup.
Abstract translation: 公开了一种用于电化学电池的电流中断机制。 热激活电流中断机构被集成到用于电化学电池的端盖组件中。 热响应机构优选地包括自由浮动双金属盘，其在暴露于升高的温度时变形，导致端盖组件内的电路径中断。 这样可防止电流流过电池并有效地关闭工作电池。 或者，热响应机构可以包括可暴露于升高的温度时熔化的材料，以破坏端盖组件内的电路径。 端盖组件还可以包括其中压力响应电流中断机构。 如果操作单元内的内部气体压力超过预定值，则压力响应机构被激活以切断端盖组件内的电路径，以防止电流通过电池。 压力响应机构可以包括当存在极端气体压力积聚时破裂的隔膜。 允许气体通过端盖组件内的一系列通气孔从电池内部逸出到外部环境。

Abstract: An electrochemical cell is presented having a pressure dissipation assembly that reversibly ceases cell operation when the internal cell pressure reaches a predetermined threshold. If, once the pressure dissipation assembly is activated, the internal pressure continues to increase to a second threshold, a venting mechanism is activated to release pressurized cell contents from the cell.
Abstract translation: 提出了具有压力耗散组件的电化学电池，当内部电池压力达到预定阈值时，该组件可逆地停止电池操作。 如果一旦压力耗散组件被激活，内部压力继续增加到第二阈值，则启动排气机构以从电池释放加压的电池内容物。
