産業上の利用分野
本発明は、鉛蓄電池の極板群の改良に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an improvement in a group of electrode plates for a lead-acid battery.
従来例の構成とその問題点
鉛蓄電池の極板群は、正、負極とセパレータの
積層体から構成される。そして、活物質の脱落に
よる内部短絡を防止するには、セパレータを断面
Ｕ字状にして一方の電極を包被するのが有利であ
る。とくに、鉛もしくは鉛合金のシートを網目状
に展開したエクスパンドメタル格子を用いる場合
は、格子の側部において活物質を保持すべき骨に
よる完全なセルを完成していないので、電極の側
面をも封じた袋状のセパレータを用いるのが有利
である。Structure of conventional example and its problems The electrode plate group of a lead-acid battery is composed of a laminate of positive and negative electrodes and a separator. In order to prevent internal short circuits due to falling of the active material, it is advantageous to make the separator U-shaped in cross section and cover one electrode. In particular, when using an expanded metal grid made of sheets of lead or lead alloy developed into a mesh, the sides of the electrode are not completely formed by the bones that should hold the active material on the sides of the grid. It is advantageous to use a separator in the form of a sealed bag.
このような袋状のセパレータを用いた場合、同
じ大きさの正、負極を用いると、一方の電極を挿
入するセパレータの巾は、当然電極の巾より大き
くなるので、一方の電極を挿入したセパレータ
と、裸の他方の電極とを交互に積層して極板群を
構成するとき、両者の巾が一致しないため積層作
業が煩雑になる不都合があつた。 When using such a bag-shaped separator, if positive and negative electrodes of the same size are used, the width of the separator into which one electrode is inserted will naturally be larger than the width of the electrode. When forming an electrode plate group by alternately stacking one electrode and the other bare electrode, there was an inconvenience that the stacking work was complicated because the widths of the two electrodes did not match.
発明の目的
本発明は、このような従来の不都合を除去する
ことを目的としたものである。OBJECT OF THE INVENTION The present invention aims to eliminate such conventional disadvantages.
発明の構成
本発明は袋状セパレータに挿入する第２電極の
幅（電極反応面の横方向の長さ）ｃを小さくし
て、セパレータの幅（横方向の長さ）ｂと、他方
の裸の第１電極の幅ａとの間に
ｂ−ｂ−ｃ／２≦ａ≦ｂ＋ｂ−ｃ／２の関係に保つ
て、極板群の積層作業を容易にしたものである。Structure of the Invention The present invention reduces the width c of the second electrode inserted into the bag-like separator (the lateral length of the electrode reaction surface), and reduces the width b of the separator (the lateral length) of the second electrode and the other bare electrode. The relationship between the width a of the first electrode and the width a of the first electrode is maintained as bb-b-c/2≦a≦b+b-c/2, thereby facilitating the lamination work of the electrode plate group.
ｂ−ｂ−ｃ／２≦ａの関係にあれば、第１電極が
片方に寄つた場合においても第２電極に対面する
ことができるため容量の低下がない。またｂ＋
ｂ−ｃ／２≧ａの関係にあれば、極板群の電槽への
挿入、および極板群形成時の積層作業も極板群の
幅がそれほど大きくならないため問題は生じな
い。 If there is a relationship of bbc/2≦a, even if the first electrode is moved to one side, it can face the second electrode, so there is no reduction in capacitance. Also b+
If the relationship b-c/2≧a holds, no problem will occur during the insertion of the electrode plate group into the battery case and the lamination work during the electrode plate group formation because the width of the electrode plate group will not become so large.
実施例の説明 以下、本発明を実施例により説明する。Description of examples The present invention will be explained below with reference to Examples.
図において、１は正極板、２は負極板であり、

である。 In the figure, 1 is a positive electrode plate, 2 is a negative electrode plate,
Both have an active material paste applied to an expanded metal grid. 3 is a separator made of a synthetic resin having appropriate elasticity and flexibility, such as polyethylene. This separator 3 has a large number of ribs 4 extending vertically on its inner surface, and after being bent into a U shape, both sides are welded to form a bag shape, into which the positive electrode 1 is inserted. 5 is the welded part.
これら正、負極およびセパレータの大きさは、

自体の大きさは、巾、高さとも正極を負極より小
さくしている。 The sizes of these positive and negative electrodes and separators are:
The width of the separator 3 into which the positive electrode 1 is inserted and the width of the negative electrode 2 are made almost equal, and the heights of the positive electrode and the negative electrode inserted into the separator are made almost the same, with the separator being higher than the negative electrode. That is, regarding the size of the electrode itself, the positive electrode is smaller than the negative electrode in both width and height.

１１′に隔壁を貫通させた導体により接続される。 6 has a vertical rib 7 on the inner surface and a saddle 8 on the bottom.
9 is a positive electrode grid lug, 10 is a negative electrode lug, and the ears 9 and 10 are welded to straps 11 and 12, respectively. The negative electrode side strap 12 is connected to the positive electrode side strap 11' of an adjacent cell by a conductor passed through the partition wall.

の組立てなどにも便利である。 According to such a configuration, the separator 3 into which the positive electrode 1 is inserted and the bare negative electrode 2 are alternately stacked with their lower ends and side surfaces aligned, thereby easily forming an electrode plate group. In addition, the positive electrode 1 with a small number of electrode plates is
Since the entire surface faces the negative electrode, the utilization rate of the active material is improved. Furthermore, by making the tabs 9 and 10 the same length, they are at the same height within the battery case, which is convenient for battery assembly.
