摘要： A thin film is used in a metallic collector in order to increase the volume energy density. However, the strength of the thin film is low, so when a negative plate or a positive plate is directly joined to a terminal base portion, even an insignificant load might cause damage, such as cutting of the metallic collector. Even in a structure where the metallic collector is joined to a highly-conductive plate-like metal or a highly-conductive plate-like resin, and where the collecting plate is joined to a terminal base portion, the connection between the collecting plate and the terminal base portion affects the battery properties. The present invention provides a rechargeable battery including an electrode group in which a metallic collector having a negative active material layer formed on a surface, a separator retaining an electrolyte, and another metallic collector having a positive active material layer formed on a surface are alternately disposed in a layered manner into a strip shape such that the separator is interposed between the two kinds of metallic collectors, and electrode plate tabs formed at ends of the two kinds of metallic collectors are joined to each of metallic collecting plates by a predetermined number, and the metallic collecting plates are joined together with pressing plates, by fitting between a bolt and a nuts, to a terminal base portion having a through-hole for the bolt.

摘要： A current collecting structure for which the installation space for current collecting plates is not increased more than necessary even if the number of electrodes to be stacked is increased to increase the capacity of a secondary battery is provided. Positive current collecting plates 41a to 41j constituting a positive current collecting plate stacking portion 27 are bent at bent portions 47a to 47j to constitute fixed portions 43a to 43j and welded portions 45a to 45j, respectively. The angles of the bent portions 47a to 47e are 80°, 90°, 100°, 110°, and 120°, respectively. The angles of the bent portions 47f to 47j are 120°, 110°, 100°, 90°, and 80°, respectively. Negative current collecting plates are also bent in the same manner.

摘要翻译：为了增加体积能量密度，在金属收集器中使用薄膜。然而，薄膜的强度低，因此当负极板或正极板直接接合到端子基部时，即使不显着的负载也可能导致金属集电体的切断等损坏。即使在金属集电体与高导电性板状金属或高导电性板状树脂接合的结构中，集电板与端子基部接合，集电板和端子基座部分影响电池性能。本发明提供一种可再充电电池，其包括电极组，其中在表面上形成有负极活性物质层的金属集电体，保持电解质的隔膜和在表面上形成有正极活性物质层的另一金属集电体交替地设置分层形成为带状，使得分离器插入在两种金属集电体之间，并且形成在两种金属集电体的端部处的电极板接片以预定数量接合到每个金属集电板，并且金属收集板通过将螺栓和螺母配合而与压板接合在具有用于螺栓的通孔的端子基部上。
