Abstract

一种端盖组件(23)、电池单体(20)、电池(100)、电池单体(20)的制造设备(2000)和方法，属于电池技术领域。端盖组件(23)包括端盖(231)、电极端子(232)和连接件(233)。端盖(231)设有电极引出孔(2311)，电极引出孔(2311)在端盖(231)的厚度方向(Z)上贯穿端盖(231)。电极端子(232)用于与电极组件(22)电连接。连接件(233)用于连接端盖(231)以将电极端子(232)固定。其中，电极端子(232)与电极引出孔(2311)相对设置，并且电极端子(231)在厚度方向上的投影与端盖(231)在厚度方向上的投影不重叠。连接件(233)起到连接电极端子(231)和端盖(231)的作用，从而将电极端子(231)与端盖(231)固定。由于电极端子(232)与电极引出孔(2311)相对设置，且电极端子(232)在厚度方向(Z)上的投影与端盖(231)在厚度方向上的投影不重叠，使得电极端子(232)的径向尺寸更小，减小了电极端子(232)所占用的空间，节省材料，具有更好的经济性。
