    • In a closure assembly for sealed rechargeable batteries, upon a metallic foil is placed a spacer having an aperture that is larger than an upwardly protruding portion of the foil but smaller than the outside diameter of the foil, and upon a metallic safety vent is placed either a spacer and a metallic cap, or a metallic cap only, the spacer and/or metallic cap having an aperture that is larger than a downwardly protruding portion of the safety vent but smaller than the outside diameter of the safety vent, so as to control and suppress deformation of the metallic foil and safety vent in the event of abnormal battery pressure increasing due to overcharging or the like and to ensure that rupture occurs at a predetermined pressure level, whereby a sealed rechargeable battery suitable for high-output applications and having high safety features is provided.
    • 在用于密封的可再充电电池的封闭组件中,在金属箔上放置有具有大于箔的向上突出部分但小于箔的外径的孔的间隔物,并且在金属安全通气口 间隔件和金属盖,或仅金属盖,间隔件和/或金属盖具有比安全通气口的向下突出部分大的孔口,但小于安全气囊的外径,以便控制 并且在由于过度充电等引起的电池电压增加异常的情况下抑制金属箔和安全排气孔的变形,并且确保在预定压力水平下发生破裂,由此适用于高输出应用并具有高的密封可充电电池 提供安全功能。

    • A sealed rechargeable battery containing an electrode unit and a liquid electrolyte in a metallic case with a bottom that is sealed with a closure assembly. The electrode unit includes a positive electrode and a negative electrode, each made up of a collector and electrode material paste coated thereon, wound around with a separator interposed therebetween. The closure assembly includes a metallic filter that forms an internal terminal and accommodates a safety mechanism provided in case of abnormal pressure rise caused by overcharging etc, a resin inner gasket, and a metallic cap that forms an external terminal superposed upon one another. A resin inner gasket is attached to the metallic filter and the end edge of the metallic filter is crimped to provide a seal. The metallic filter and all the metallic parts encased in the metallic filter are joined together by welding. This closure assembly design enables high power output and high-current discharge of the battery with low resistance.
    • 一种密封的可充电电池,其包含金属壳体中的电极单元和液体电解质,其底部用封闭组件密封。 电极单元包括正极和负极,每个由集电体和涂覆在其上的电极材料浆料组成,其间隔开隔膜。 闭合组件包括金属过滤器,其形成内部端子并且容纳在由过充电等引起的异常压力升高的情况下提供的安全机构,树脂内垫圈和形成彼此重叠的外部端子的金属盖。 树脂内垫圈附接到金属过滤器,并且金属过滤器的端边缘被压接以提供密封。 金属过滤器和包裹在金属过滤器中的所有金属部件通过焊接连接在一起。 该闭合组件设计可实现低电阻的高功率输出和大电流放电。
