    摘要： A sealed battery includes a lid closing a container of a sealed battery, an upper current collecting plate, a lead connecting an upper surface to an inner surface of the lid. A welding point of the lead is outside a position corresponding to a periphery of the cap. The lead includes a cylindrical lateral wall part extending vertically, an annular frame portion extending substantially horizontally from a first end of the lateral wall part, and a plurality of supplementary leads that extends substantially horizontally from a second end part of the lateral wall part. The frame portion extends from the first end part in substantially a first direction along a radial direction of the cylindrical lateral wall part, whereas the plurality of supplementary leads extends from the second end part in substantially a second direction opposite to the first direction along the radial direction.

    摘要： The object of the invention is to provide a sealed battery having a low resistance and is excellent in output power performance, and a lead suitable for the sealed battery, and a battery stack comprising a plurality of such sealed batteries as described above, Provided is a sealed battery comprising a lid (50) for closing the open end of a container (60) which has, at the center of its upper surface, a valve body (90) covered with a cap (80) to form a safety valve, and an upper current collecting plate (2) connected via lead (20, 30) to the inner surface of lid (50), wherein a welding point of lead (20) to the inner surface of lid (50) is, in a flat view, outside the periphery of cap (80), and the length of lead (20, 30) from the welding point (20) on the inner surface of lid (50) to the nearest welding point (30) on the upper current collecting plate (2) is 1 to 2.1 times as large as the shortest distance between the welding point (20) of lead on the inner surface of lid (50) and the upper surface of upper current collecting plate (2). In addition, a welding point formed by the lead (30) on the upper current collecting plate (2) falls in a circular band enclosed between a concentric circle around the center of upper current collecting plate (2) and having a radius 41% of the radius of said plate, and another concentric circle having a 69% radius. Welding points (100-1) formed between the lower surface of a lower current collecting plate (100) and the upper surface of bottom of container (60) are disposed, in a flat view, laterally outside the peripheral margin of a cap (80). The lead used for such a sealed battery may be shaped like a ring (20, 30) or a double-walled ring having a frame portion and lateral wall portions. Such sealed batteries may be combined to form a battery stack
