摘要： A power storage cell (1) comprises an electrode assembly (100) including a plurality of tabs (110P, 110N), a cell case (200), an external terminal (300), a connecting member (400), and an insulating member (500). The connecting member (400) has a current collector plate (410) connected to the plurality of tabs, and a connecting pin (420) connecting the current collector plate and the external terminal. The insulating member (500) includes an insulator (520) that has a shape surrounding the connecting pin and that insulates the connecting pin from the cell case. The connecting pin (420) has a covered portion (422) covered with the insulator, and the covered portion (422) has a fuse portion (422a).

摘要： A power storage cell (10) includes an electrode assembly (100), a cell case (200), and an external terminal (300). The cell case (200) houses the electrode assembly (100). The external terminal (300) is fixed to the cell case (200). The external terminal (300) includes a first terminal portion (310) and a second terminal portion (320). The first terminal portion (310) is arranged above the cell case (200). The second terminal portion (320) extends from the first terminal portion (310) along the side surface of the cell case (200). The second terminal portion (320) is provided with a recess (321). The recess (321) is formed on a surface of the second terminal portion (320) opposite to the other surface thereof that faces the cell case (200).

摘要： A laminated battery comprises: an electrode body (40); side surface members (20) disposed at side surfaces (fore and aft) of the electrode body (40);a laminate sheet (30) covering the electrode body (40); and side surface resin members (10) mounted to side surfaces (S30), which are at side surface member sides of the laminate sheet (30), wherein the side surface members (20) and the laminate sheet (30) are welded; the laminate sheet (30) has a middle metal layer (31), and the side surface resin members (10) cover the metal layer (31) of the side surfaces (S30) of the laminate sheet (30). This way the metal layer (31) is electrically insulated on all sides.
