    • The apparatus of the present invention provides a cover for venting gases from thin metal film battery cells having vents disposed at the center of one end of the cells. The vents comprise cylindrical wells that recess into, and substantially fill, the top portions of battery cell cavities within a battery housing. The cavities are sized to hold the battery cells securely and are configured to provide an electrical serial connection. The wells include pipes which extend outward from the bottom of the wells and lead from openings in the bases of the wells. The openings in the pipes are covered with flexible valve caps and well lids cover the wells. The center point arrangement of the recessed wells permit gases from the battery cells to escape through the openings, yet restrict the electrolyte from exiting the housing. The base of the battery housing does not have vent openings and is interchangeable with the cover so that the battery housing may be oriented with the terminals near the top or the bottom of the case.
    • 本发明的装置提供了一种用于从具有设置在单元的一端的中心的通气孔的薄金属膜电池单元排出气体的盖。 通风口包括凹入电池壳体内的电池单元腔的顶部并基本上填充的圆柱形孔。 空腔的尺寸被设计成牢固地保持电池单元并且被配置成提供电串联连接。 井包括从井的底部向外延伸并从井的底部的开口引出的管。 管道中的开口被柔性阀盖覆盖,井盖覆盖井。 凹槽的中心点布置允许来自电池单元的气体通过开口逸出,但是限制电解液离开壳体。 电池壳体的底部没有通气口并且可与盖互换,使得电池壳体可以被定位成使得端子靠近壳体的顶部或底部。
