不良が発生したり、サイクル寿命が設計値より短かいも
のが発生している。A separator, which consists of a certain number of negative electrode plates stacked one on top of the other, and a positive electrode plate 3, a separator 6, a negative electrode plate 4, There is a method in which each band is layered in a spiral shape and then inserted. When constructing a group of electrode plates using the above-mentioned methods, the flatness and precision of the electrode plates are very important when stacking certain electrode plates and separators. Suppose the electrode plate is bent.
When several dozen sheets are stacked on top of each other, the apparent thickness increases, and they cannot fit into a fixed container (container case), making the work process extremely complicated and requiring a large number of man-hours. On the other hand, if external pressure is applied to maintain a constant thickness of the electrode plate group, the separator between the electrode plates may be damaged, resulting in leakage defects or shorter cycle life than the designed value.

ラツキが太きいという欠点がある。A storage battery that is formed by stacking a positive electrode plate, a separator, and a negative electrode plate one on top of the other in a spiral shape requires extremely flexible electrode plates. If you use a conventional electrode plate and make it into a spiral shape, both the positive and negative electrode plates will not form a smooth circular shape, as shown in Figure 2.
Since convex portions occur during the circular process, the cycle life was sometimes shorter than the designed value. Another drawback is that there is wide variation in the performance of the single cells.
