固定し、シュリンクチューブに入れて熱収縮させた。As shown in FIG. 3, the present invention covers an electrode plate group 4 consisting of a positive electrode plate 1, a negative electrode plate 2, and a separator 3 with a frame body 5 made of polyethylene, and a polyethylene film is placed on the inner side in contact with the electrode plate group 4, as shown in FIG. Two metal plates 7 and 7j made of Nuzu plated steel laminated with a copolymer film 6 with acrylic acid are sealed by heat welding, and electrode plate ears 8, 8' and metal plate tabs 9, 9 are sealed.
' and welded the metal plates 7, 7' to the current collecting part to form a safety valve 1o.
Attach them to form the unit cell 15, arrange the three pieces side by side as shown in Figure 1, paste the copper foil 11 on adjacent metal plates of different polarities, spot weld them to electrically connect them, and glue them on both sides. The thickness of the adhesive tape pasted is 0.3. A fixing plate 14 made of polypropylene was pasted on both sides of the unit cell group and fixed under pressure, and then placed in a shrink tube and heat-shrinked.

が出来る。Effects of the Invention As described above, the battery of the present invention is protected against drops and abrasions, and even if the shrink tube as an exterior body is torn, the fixed plate is thick and protects the metal plate connected to the electrode plate from being exposed. It can prevent short circuits and improve safety. Furthermore, by changing the partial fixation between the batteries with tape to the complete fixation between the batteries with a resin plate, it is possible to provide an assembled battery that does not easily bend even when bending force is applied, although the thickness increases slightly.
