Reference numeral 1 denotes a unit cell, 2 denotes a separator, and an anode plate 3 is arranged on one surface side and a cathode plate 4 is arranged on the other surface side to form an electrode plate group. Reference numeral 5 denotes a frame corresponding to a battery case of the unit cell 1, which surrounds the outer periphery of the unit cell 1 and includes an electrode plate group including a separator 2, an anode plate 3, and a cathode plate 4. Reference numeral 6 denotes a current collecting plate disposed so as to be electrically connected to the anode plate 3 and the cathode plate 4, respectively. The outer peripheral edge of the current collecting plate 6 is welded and fixed to the side surface of the frame 5. As a method of welding and fixing, for example, the resin film film coated on the inner surface of the current collector 6 and the ribs provided on the side surfaces of the frame 5 are melted and fixed to each other. As described above, the unit cell 1 has the above-described electrode plate group built in a flat battery case surrounded by a frame 5 and two current collector plates 6, and an electrolyte is injected into this to form a battery. ing.

The protruding portion 9 is also a portion where the current collector plates 6 of different polarity of the unit cell 1 are in contact with each other. Since the projecting portion 9 is a side surface of the current collecting plate 6 made of a metal or other conductive material, when this portion is connected by connecting means such as brazing or various weldings, the connection between the unit cells is completed. . Therefore, the outermost current collecting plate 6 of the assembled battery composed of three unit cells shown in this embodiment is charged to the anode and the cathode, respectively.

接着及び固着強度を高める必要がある。One or two recesses provided on the outer wall of the frame may be provided on each side of the frame. In this case, the projecting portion of the current collecting plate 6 also increases accordingly. In the case where the unit cells 1 are stacked to form an assembled battery, as the number of the unit cells increases, the entire unit becomes heavier by its own weight, and the shock when handling the assembled battery increases accordingly. It is necessary to increase the bonding and fixing strength.
