他極と完全に分離することにより、極板底部および極板
側部での内部短絡を防止する効果が従来の板状セパレー
タよりも優れている。BACKGROUND ART In recent years, bag-shaped separators have been frequently used as separators for lead-acid batteries. The bag-like separator encloses either the positive electrode plate or the negative electrode plate,
By completely separating from the other electrode, the effect of preventing an internal short circuit at the bottom portion and the side portion of the electrode plate is superior to the conventional plate-like separator.

セパレータに内包されている場合、正極板が腐食により
膨脹して袋の内寸以上となり、正極板が袋の側部を破き
内部ショートに至ることもある。この現象は最近の鉛蓄
電池の使用環境が高温雰囲気になってきたためであり、
新たな課題としてクローズアップされるようになった。Problems to be Solved by the Invention However, even if a bag-shaped separator is used, the above problems are not completely solved. That is, when the positive electrode plate is included in the bag-shaped separator, the positive electrode plate expands due to corrosion to become larger than the inner size of the bag, and the positive electrode plate may break the side portion of the bag and cause an internal short circuit. This phenomenon is due to the recent use environment of lead-acid batteries becoming high temperature atmosphere,
It has come to the fore as a new issue.
この課題の解決方法として、セパレータの内寸法より
十分に小さい寸法の極板を用いる試みがなされてはいる
が、この方法では電池性能、特に高率放電性能の低下を
招くため、得策な方法ではない。As a solution to this problem, an attempt has been made to use an electrode plate having a size sufficiently smaller than the inner size of the separator.However, this method causes a decrease in battery performance, particularly high-rate discharge performance. Absent.
本発明は他の電池性能を低下せしめることなく、上記
課題を解決し、長寿命の電池を提供することを目的とし
たものである。An object of the present invention is to solve the above-mentioned problems and provide a long-life battery without deteriorating the performance of other batteries.
課題を解決するための手段 本発明は上記目的を達成するために、左右両端を上下
方向にシールすることにより上部に開口部を有する袋状
セパレータと、このセパレータに収納される正極板とを
備え、前記袋状セパレータに折筋状にラインリブを正極
板面に対向するように上下方向に設けた構成とするもの
である。Means for Solving the Problems In order to achieve the above object, the present invention comprises a bag-shaped separator having an opening at the top by vertically sealing both left and right ends, and a positive electrode plate housed in the separator. A line rib is provided in the bag-shaped separator in a vertical direction so as to face the positive electrode plate surface.
作用 電池を高温雰囲気で使用すると過充電電流が多く流
れ、格子の腐食により正極板は膨脹し、正極板の寸法が
袋状セパレータの内寸法以上となり、正極板が袋状セパ
レータに内包されている構成の電池では側部が破れてし
まうこともある。本発明の技術を用いた場合において
は、正極板が膨脹してセパレータの内寸法以上になって
も、ラインリブ部分が変形し、セパレータの内寸法が変
化するため、側部でのセパレータの破れを完全に防止す
ることができる。Function When a battery is used in a high temperature atmosphere, a large amount of overcharge current flows, the positive electrode plate expands due to corrosion of the grid, the size of the positive electrode plate becomes larger than the inner size of the bag-shaped separator, and the positive electrode plate is included in the bag-shaped separator. In the battery having the configuration, the side portion may be broken. In the case of using the technology of the present invention, even if the positive electrode plate expands and becomes larger than the inner size of the separator, the line rib portion is deformed and the inner size of the separator changes, so that the separator is broken at the side portion. It can be completely prevented.
この技術は、ほとんど伸展性を有しないセパレータす
なわちガラス繊維や合成繊維を主成分とした抄造体であ
る場合には極めて有効である。This technique is extremely effective in the case of a separator having almost no extensibility, that is, a paper body mainly composed of glass fiber or synthetic fiber.
従来よりラインリブを備えた膜とガラスマットとを貼
り合わせたものを板状セパレータとして用いたものがあ
ったが、それは高率放電時の持続時間の向上と、セパレ
ータの低コスト化を目的とするものであり、本発明の目
的とは全く異なるものである。Conventionally, there has been used a plate-like separator obtained by laminating a film with a line rib and a glass mat as a plate-shaped separator, which aims to improve the duration during high-rate discharge and reduce the cost of the separator. This is completely different from the object of the present invention.
実施例 以下、本発明の効果を実施例にて説明する。Examples Hereinafter, effects of the present invention will be described with reference to examples.

定電圧過充電を行った。First, a bag-shaped separator provided with line ribs using the technique of the present invention as shown in FIG. 1 (battery: A) and a conventional separator not provided with line ribs as shown in FIG. 2 (battery: B) Was used to prepare a battery having a capacity of 48 Ah (5 hour rate capacity). These batteries were overcharged at a constant voltage of 2.4 V / cell at 60 ° C.
