Description
【発明の詳細な説明】 産業上の利用分野 本発明は蓄電池に関するものである。[Detailed description of the invention] Industrial applications The present invention relates to storage batteries.
従来の技術とその問題点

極板と負極板とのショートを防止する構成となっている
。Conventional technology and its problems In conventional storage batteries, a separator that is wider than the positive and negative plates is placed between the positive and negative plates to prevent short circuits between the positive and negative plates. It becomes.
ところで近年、極板として長尺の鉛シートをエキスバン

わゆるエキスバンド方式に一ネる極板の製造方法が実用
化されている。By the way, in recent years, a long lead sheet has been expanded into a wire-like material as an electrode plate, an active material is continuously coated on this long material, and a porous sheet is then pasted on the surface. Subsequently, this is cut into a desired electrode plate width to produce an electrode plate. A method of manufacturing an electrode plate, which is similar to the so-called expanded method, has been put into practical use.

ョートが発生して実用に供せない。If such an electrode plate is used with a separator attached instead of a porous sheet, the manufacturing process of the storage battery can be simplified. However, from the viewpoint of manufacturing the above electrode plate, it is possible to make the separator wider in the height direction of the electrode plate, but it is not possible to make the separator wider in the width direction of the electrode plate. If they are stacked on top of each other, a short circuit will occur and it cannot be put to practical use.
発明の目的
本発明は以上の点に鑑みてなされたものであり、例えば

This is what we propose.

It is characterized by the presence of

られている。こうして極板２とセパレータ３とは幅方向
において同一幅であり、他方、上下方向では極板２より
もセパレータ３が広く配されている。In the drawings, reference numeral 1 denotes an electrode plate separator bonded product formed by an expanded method, and a separator 3 mainly made of glass fibers with a fiber diameter of 1 μm or less is on both sides of an electrode plate 2 consisting of a positive electrode plate or a negative electrode plate. It is pasted during the production of electrode plates, and the thus obtained elongated material is cut into desired widths. The electrode plate 2 is not formed with an electrode foot portion, and is attached to the separator 3 in a floating manner. Thus, the electrode plate 2 and the separator 3 have the same width in the width direction, and on the other hand, the separator 3 is disposed wider than the electrode plate 2 in the vertical direction.

となって積重ねられる。The electrode plate separator bonded article 1 thus formed is then transferred to the second
As shown in the figure, a positive electrode plate separator bonded product 1a and a negative electrode plate separator bonded product 1b are stacked alternately to form an electrode group such that their ears 4 are lined up on opposite sides. At this time, the positive electrode plate separator bonded product 1a and the negative electrode plate separator bonded product 1b are stacked with being shifted in the width direction. That is, since the positive electrode plate separator bonded product 1a and the negative electrode plate separator bonded product 1b have the same width, they are stacked so that they each protrude toward the negative side.
このような構成とすることにより、極板セパレータ接合
物１の表面のセパレータ３により、正極板２ａと負極板
２ｂとは直接接触することはなく、従って蓄電池の機能
に支障はない。With such a configuration, the positive electrode plate 2a and the negative electrode plate 2b do not come into direct contact with each other due to the separator 3 on the surface of the electrode plate separator assembly 1, so that there is no problem with the function of the storage battery.
