    • In a battery pack including rechargeable batteries arranged in parallel, a cooling medium path for allowing a cooling medium to horizontally flow be formed between the rechargeable batteries. A cooling medium delivery device for delivering the cooling medium to the cooling medium path is provided so as to reduce a height of the battery pack including a cooling device. The cooling medium delivery device is constituted by a pair of cooling medium introduction ducts provided on both right and left sides of the battery pack, each having delivery ports for delivering the cooling medium alternately in horizontally opposed directions to each of the cooling medium paths, and a cooling medium compression transport device for supplying the cooling medium to both of the cooling medium introduction ducts.
    • 在包括并联布置的可再充电电池的电池组中,在可再充电电池之间形成用于允许冷却介质水平流动的冷却介质路径。 提供了用于将冷却介质输送到冷却介质路径的冷却介质输送装置,以便降低包括冷却装置的电池组的高度。 所述冷却介质输送装置由设置在所述电池组的左右两侧的一对冷却介质导入管构成,所述一对冷却介质导入管各自具有用于将冷却介质交替地沿水平方向输送到各冷却介质路径的排出口, 冷却介质压缩输送装置,用于将冷却介质供应到两个冷却介质导入管道。

    • Provided are a low-cost battery in which an outermost first electrode plate is designed to be bent at a bent portion farther from a current collector than its own joint end so that a near portion extending from the bent portion to the joint end is positioned inward in a lamination direction than a distant portion positioned farther from the current collector than the bent portion, and first electrode plates including the outermost first electrode plate are connected to a collector joint part, and a manufacturing method thereof. In the battery of the invention, a negative collector joint part is connected to a negative joint end of an inside negative electrode plate with a fillet formed of metal melted from the negative collector joint part itself and also connected to a negative joint end of an outermost negative electrode plate with a fillet formed of metal melted from the negative collector joint part itself.
    • 提供一种低成本电池,其中,最外侧的第一电极板被设计成在比集电体比其自身的接合端更弯曲的部分弯曲,使得从弯曲部延伸到接合端的近部位于内侧 在比与弯曲部分更远离集电体的远处部分的层叠方向上,并且包括最外面的第一电极板的第一电极板连接到集电器接合部分及其制造方法。 在本发明的电池中,负极集电体接合部与内部负极板的负极接合端部连接,该负极接合端部具有由负极集电体接合部本身熔化的金属形成的圆角,并且还连接到最外侧的负极接合端 负极板具有由负极集电体接合部本身熔化的金属形成的圆角。
