Description
本発明は、円筒形密閉式鉛蓄電池及びその製造方法に関するものである。 The present invention relates to a cylindrical sealed lead-acid battery and a method for manufacturing the same.
円筒形密閉式鉛蓄電池の極板群である捲回群は、長尺の正極板と負極板とをセパレータを介して渦巻き状に捲回した構造となっている。捲回時には、長尺の比較的柔らかい極板を取り扱うため、活物質の脱落を防止することは重要な課題である。一方、捲回群は長尺な極板を捲回した構造であるため、巻ずれの発生しにくい構造であることが要求される。 A wound group, which is an electrode plate group of a cylindrical sealed lead-acid battery, has a structure in which a long positive electrode plate and a negative electrode plate are wound in a spiral shape with a separator interposed therebetween. When winding, a long and relatively soft electrode plate is handled, so it is important to prevent the active material from falling off. On the other hand, since the wound group has a structure in which a long electrode plate is wound, it is required to have a structure in which winding deviation is unlikely to occur.
このため、極板に貼り付けるセパレータとしてペースト紙を用い、該ペースト紙にスリット加工を施すことにより活物質の脱落を防止し、且つ巻ずれを防止することが提案されている(例えば、特許文献1参照。)。これにより、巻ずれを防止することができる。
しかしながら、高速で捲回を行うと、極板に貼り付けたペースト紙の破断が不規則に発生するようになるため、十分な巻きずれ防止効果が得られない問題点があった。また、ペースト紙にスリット加工を施すために、ロール状に捲かれた状態のペースト紙にスリット加工を施すと、スリット間隔が規定できない問題点があった。さらに、極板に貼り付けた後のペースト紙にスリット加工を行うと、極板を傷つけてしまう問題点があった。 However, when winding is performed at high speed, the paste paper affixed to the electrode plate is irregularly broken, so that there is a problem that a sufficient winding prevention effect cannot be obtained. Further, when slit processing is performed on paste paper that has been rolled up in order to perform slit processing on the paste paper, there is a problem that the slit interval cannot be defined. Furthermore, when the slit processing is performed on the paste paper after being attached to the electrode plate, there is a problem that the electrode plate is damaged.
本発明の目的は、捲回群の捲回中心からの径の変化に応じた間隔でペースト紙にスリットが入っている円筒形密閉式鉛蓄電池を提供することにある。 An object of the present invention is to provide a cylindrical sealed lead-acid battery in which slits are provided in paste paper at intervals corresponding to changes in diameter from the winding center of a winding group.
本発明の他の目的は、ペースト紙にスリットを所要の間隔で入れることができる円筒形密閉式鉛蓄電池の製造方法を提供することにある。 Another object of the present invention is to provide a method for manufacturing a cylindrical sealed lead-acid battery capable of inserting slits in paste paper at a required interval.
本発明は、上記の目的を達成するためになされたものである。 The present invention has been made to achieve the above object.
本発明は、正極板と負極板とがセパレータを介して捲回された捲回群を持つ円筒形密閉式鉛蓄電池を対象とする。 The present invention is directed to a cylindrical sealed lead-acid battery having a wound group in which a positive electrode plate and a negative electrode plate are wound through a separator.
本発明に係る円筒形密閉式鉛蓄電池では、極板はその表面にペースト紙が存在し、該ペースト紙には巻き取り方向とは直交する方向にスリットが施されており、スリットの間隔は捲回群の中心から外周に向かって広くなっていることを特徴とする。 In the cylindrical sealed lead-acid battery according to the present invention, the electrode plate has paste paper on the surface thereof, and the paste paper has slits in a direction perpendicular to the winding direction, and the interval between the slits is small. It is characterized by becoming wider from the center of the rotation group toward the outer periphery.
また、本発明に係る円筒形密閉式鉛蓄電池の製造方法では、ペースト紙を極板の上下に配置したロールの表面に沿って極板の表面に貼り付け、ロールの表面をペースト紙が通過する際に該ペースト紙に所要の間隔でスリット加工を施すことを特徴とする。 Moreover, in the manufacturing method of the cylindrical sealed lead-acid battery according to the present invention, the paste paper is attached to the surface of the electrode plate along the surface of the roll disposed above and below the electrode plate, and the paste paper passes through the surface of the roll. In this case, the paste paper is slitted at a required interval.
この場合、スリットの巻き取り方向の間隔は、正極板と負極板とをペースト紙を介して捲回して形成する捲回群の中心から外周に向かって巻き取り方向に広くする。 In this case, the interval in the winding direction of the slit is increased in the winding direction from the center of the wound group formed by winding the positive electrode plate and the negative electrode plate through paste paper toward the outer periphery.
本発明に係る円筒形密閉式鉛蓄電池では、極板の表面に存在するペースト紙にその巻き取り方向とは直交する方向に設けているスリットの巻き取り方向の間隔を、捲回群の中心から外周に向かって巻き取り方向に広くしているので、換言すれば、スリットの巻き取り方向の間隔を捲回群の中心に向かって巻き取り方向に狭くしているので、捲回群の中心における極板の湾曲度合いが大きいゆえに、このように捲回群の外周よりもペースト紙のスリット間隔を小さくすることで、ペースト紙が極板に追随して湾曲し易くなり、安定して巻きずれを防止することができる。 In the cylindrical sealed lead-acid battery according to the present invention, the interval in the winding direction of the slit provided in the direction perpendicular to the winding direction on the paste paper existing on the surface of the electrode plate is determined from the center of the winding group. In other words, since the gap in the winding direction of the slit is narrowed in the winding direction toward the center of the winding group, in the center of the winding group. Since the degree of curvature of the electrode plate is large, by making the slit distance of the paste paper smaller than the outer periphery of the winding group in this way, the paste paper can easily follow the electrode plate and bend, and the winding can be stably prevented. Can be prevented.
また、本発明に係る円筒形密閉式鉛蓄電池の製造方法では、ペースト紙を極板の上下に配置したロールの表面に沿って極板の表面に貼り付け、ロールの表面をペースト紙が通過する際に該ペースト紙に所要の間隔でスリット加工を施すので、ロール状に巻き取られたペースト紙を引き出して極板に貼り付ける直前にスリット加工が行われ、このため極板に傷を付けることなく、極板長さに対応して所定の位置にスリット加工を施すことができる。 Moreover, in the manufacturing method of the cylindrical sealed lead-acid battery according to the present invention, the paste paper is attached to the surface of the electrode plate along the surface of the roll disposed above and below the electrode plate, and the paste paper passes through the surface of the roll. When the paste paper is slit at the required interval, slitting is performed immediately before the paste paper wound up in a roll is pulled out and pasted to the electrode plate, and thus the electrode plate is damaged. In addition, slit processing can be performed at a predetermined position corresponding to the electrode plate length.
この場合、スリットの巻き取り方向の間隔を、正極板と負極板とをペースト紙を介して捲回して形成する捲回群の中心から外周に向かって巻き取り方向に広くすると、巻きずれを防止することができる。 In this case, if the gap in the winding direction of the slit is widened in the winding direction from the center of the wound group formed by winding the positive electrode plate and the negative electrode plate through paste paper in the winding direction, winding deviation is prevented. can do.
以下、本発明を実施するための最良の形態を、実施例に基づいて詳細に説明する。 Hereinafter, the best mode for carrying out the present invention will be described in detail based on examples.
厚さ0.7mmの鉛合金箔を用いて、幅80mm×長さ600mmの極板基体を打ち抜き、格子体からなる集電体を作製した。 Using a lead alloy foil having a thickness of 0.7 mm, an electrode plate base having a width of 80 mm and a length of 600 mm was punched to produce a current collector made of a lattice.
次に、この集電体を用いて電極を作製した。正極板は、酸化度70%の鉛粉と希硫酸とを混練して活物質ペーストを得、この活物質ペーストを集電体に充填して形成した。負極板は、酸化度70%の鉛粉に少量の炭素粉末、リグニン、バリウム、化合物を加え、希硫酸と混練して活物質ペーストを得、この活物質ペーストを集電体に充填して形成した。 Next, an electrode was produced using this current collector. The positive electrode plate was formed by kneading lead powder having an oxidation degree of 70% and dilute sulfuric acid to obtain an active material paste, and filling the active material paste into a current collector. The negative electrode plate is formed by adding a small amount of carbon powder, lignin, barium, and a compound to lead powder with an oxidation degree of 70%, kneading with dilute sulfuric acid to obtain an active material paste, and filling the current collector with this active material paste did.
次に、ペースト紙を各極板の表面に貼り付けて、セパレータとしてのこれらペースト紙付きの正極板と負極板とをガラスマットセパレータを介して捲回して、表1に示すような捲回群を作製した。ここで、捲回群(1)は従来例、捲回群(2)は本発明例である。
