    Abstract: A forming die including of a holder having an upper portion and a lower portion, each portion having a main substrate extending in a first longitudinal direction. A fixing substrate is located on one end of the main substrate and a movable substrate is located on an opposite end of the main substrate and is movable along the main substrate in the first longitudinal direction. A plurality of die forming segments are situated between the movable substrate and the fixing substrate. Tie rods extend along the main substrate outside the periphery of the plurality of die forming segments, and connect the movable substrate and the fixing substrate to one another.

    Abstract: To provide a lithium secondary cell, which is excellent in productivity since a cell structure is simple and easy for assembly. Provided is a lithium secondary cell having: an internal electrode body including a positive electrode plate, a negative electrode plate, the positive electrode plate and the negative electrode plate being wound and laminated around an external periphery wall of a hollow cylindrical winding core, and inside the internal electrode body a nonaqueous electrolyte solution being impregnated, a cylindrical cell case contained in this internal electrode body 1 with both ends being opened, and two electrode caps sealing the above described internal electrode body 1 at both the open ends of this cell case. The electrode cap has a plate member sealing the internal electrode body and disposed so as to seal both the open ends of the above described cell case, an external terminal member protruding onto the surface of the electrode caps to lead out currents to outside, and an internal terminal member brought into connection with the internal electrode body and taking out currents from the internal electrode body, and an elastic body and at least two of the above described plate member, the external terminal member and the internal terminal member are joined together for construction. Furthermore, there is also provided an assembly of lithium secondary cells.

    Abstract: A lithium secondary cell wherein an electrode assembly (1) comprising a positive plate and a negative plate that are wound or stacked through a separator and impregnated with a nonaqueous electrolytic solution is contain ed in a cylindrical cell case (16) having electrode caps at both ends, an elast ic body (23) is disposed between the cell case (16) and each of the electrode caps, and the cell case is sealed through a caulking part formed by pressing the portion of the cell case in contact with each of the elastic bodies (23) . The relation between the diameter Rbody (mm) of the body portion of the cell case (16) and the diameter Rtop (mm) of each of the caulking parts is expressed by Rbody>Rtop. By strengthening the caulking between the cell c ase and each of the electrode caps, there is no gaps among the cell case and the electrode caps in the caulking parts, thereby preventing leak of the electrolytic solution and improving the long-term stability and reliability.
