Abstract

PURPOSE:To prevent any inhomogeneity in the interelectrode distances and the like of a positive and a negative plate by gradually decreasing tensile force, applied in the opposite direction to the direction in which a separator and the plates are sent toward a wound core in the rolling process, from the beginning to the end of the rolling of the plates. CONSTITUTION:In sending a positive and a negative plate 1 and 2 and a separator 3 interposed between them toward a wound core 4 in rolling these members around the wound core 4, tensile force is applied by an electromagnet, a cylinder or the like in the opposite direction to the direction in which the members are sent out as indicated by an arrow. Besides the tensile strength is gradually decreased from the beginning to the end of the rolling, so that a part of the plate near the wound core of the spiral electrode body is intensely pressed immediately after being wound and is not pressed by a part of the plate near the outer periphery of the spiral electrode body almost entirely afterward. As a result, when the rolling is finished, interelectrode distances and the like of the positive and the negative plates 1 and 2 near the wound core and near the outer periphery of the spiral electrode body can be made more homogeneous compared to the conventional method. Consequently, the performance of a battery can be increased.

One of the reasons for this is that when the positive and negative poles are wound in a spiral, and the distance between the positive and negative poles becomes uneven, the reaction current will concentrate locally and the reaction overvoltage will increase. It is thought that the terminal voltage becomes lower. In order to prevent the terminal voltage from decreasing during discharge due to winding the positive and negative ridges in a spiral shape, the spiral 't[ The winding should be adjusted so that the drawing board is evenly compressed in the vicinity of the core and periphery of the riU body.

不均一になるという欠点があった。Conventionally, in the process of spirally winding the separator inserted between the winding core, the winding core, and the separator inserted between the winding boards, the process was carried out without applying a single tensile force in the opposite direction to the winding direction. In this case, as the first layer is wound, the drawing board near the core of the spiral wire body is compressed by the layer near the outer periphery.
There was a drawback that the oil amount distance between the positive and negative drawing boards near the winding core and the outer periphery was uneven.

The above-mentioned drawbacks of the conventional method have been eliminated by gradually decreasing the tensile force from the beginning to the end of winding the own plate.

られる。Use the winding core to create positive and negative action plates and these l! ! ll inserted between the plates t'L f: In the process of spirally winding the separator, when feeding the separator and drawing board toward the winding core, a tensile force is applied in the direction opposite to the feeding direction as shown by the arrow in Figure 1. If this tensile force is applied to an electromagnet or cylinder and gradually decreased between the beginning and the end of the winding of the drawing board, the toothed plate near the core of the spiral 1t111 body will be strongly compressed immediately after being wound, and the drawing board will further 1 near the outer periphery of the spiral electric melt even as it is wound! ]! Since there is almost no pressure from the board, when the tiill board is finished winding, the positive side of the drawing board near the core and the outer periphery, the distance between the curves, etc. will be more uniform compared to the conventional method. Therefore, the spiral ttt of the present invention is more uniformly wound than the conventional method.
