いる。(b) Conventional technology and problems In batteries using spiral electrodes, the separator is made into a bag shape in order to separate the positive and negative electrodes as well as to prevent peeling of the active material from the electrode plate and internal short circuits due to dendrite growth.
A spiral electrode is produced by putting one or both of a positive electrode plate and a negative electrode plate in it and encapsulating it, and then stacking the positive electrode plate and negative electrode plate in the encapsulated state and winding them in a spiral shape. There is.

であるだけでなく作業性にも問題がある。However, when the separator is spirally wound in this manner, the thickness of the electrode plate inserted therein is also added to the separator, so that the required length is considerably different between the outer circumferential side and the circumferential side. However, since the separator is made to have the same length on the outer and inner sides, it is hoped that the outer side will expand and the separator will contract on the circumferential side, but in reality it cannot shrink, so the inner side Wrinkles appear in the area. Pressure between the electrodes concentrates at the wrinkled portion, causing damage to the wrinkled portion and causing an internal short circuit. As a method for preventing this damage, Japanese Patent Application Laid-Open No. 60-2:9964
proposed that a heat-sealed portion be provided perpendicular to the winding direction to prevent the occurrence of large wrinkles. However, this method requires the provision of many heat-sealed parts, which is not only troublesome but also poses problems in workability.

製される。Then, these separator materials are made into a bag shape, and one or more linear or narrow band-shaped heat-sealed parts are provided on one side of the bag in parallel with the length direction of the bag. In addition, when the separator material has multiple layers, it is preferable that the entire constituent sheet is bonded by this heat-sealed portion. A spiral electrode according to the present invention is produced by inserting at least one of the positive and negative polar plates into this bag-shaped separator and winding it with the surface provided with the heat-sealed portion inside.

短絡が防止される。In a spiral electrode, the largest wrinkles on the separator occur in the center, which overlap in two or three layers, and are most susceptible to pressure from the electrode and are easily damaged. However, since the heat-sealed part in this invention has greater mechanical strength than the non-heat-sealed part, it is difficult to wrinkle even in the center of the spiral electrode, so it is less likely to break. Prevented.

比べれば短絡防止の効果は大きいが、複数にすると更に
効果が大きくなる。Even if there is only one heat-sealed part, the effect of preventing short circuits is greater than when there is no heat-sealed part, but if there are a plurality of heat-sealed parts, the effect becomes even greater.
