産業上の利用分野
本発明は鉛蓄電池及びその製造方法に関するものである
。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a lead-acid battery and a method for manufacturing the same.
従来技術とその問題点
鉛蓄電池において生産性を向上させるべく、連Ｉｉ極板
製造方法が提案され実用化されている。Prior Art and Its Problems In order to improve the productivity of lead-acid batteries, a method for manufacturing series Ii electrode plates has been proposed and put into practical use.
エキスバンドメタル、ネット、パンチングメタル等の帯
状連続体の格子体、または連続鋳造法により連続体とし

製造方法である。この製造方法では、充填したペースト
の脱落を防ぐために活物質が完全に乾燥硬化するまで、
極板の両面に紙を密着させておく必要がある。しかし、
この紙は最終的には不必要なもので途中の工程でこの紙
を除去しなければならず、これは工程の煩雑化と電池の
コストアップとなる欠点がある。A paste-like active material made of lead powder, sulfuric acid, water, etc. is mechanically filled into a lattice of a strip-shaped continuous body such as expanded metal, net, or punched metal, or a lattice body cast as a continuous body by a continuous casting method. In this manufacturing method, both sides of the active material are covered with coated paper, and after drying, the paper is removed and cut into electrode plates. In this manufacturing method, the active material is completely dried and hardened to prevent the filled paste from falling off.
It is necessary to keep the paper in close contact with both sides of the electrode plate. but,
This paper is ultimately unnecessary and must be removed during the process, which has the disadvantage of complicating the process and increasing the cost of the battery.

程特殊な切断加工法を用いねばならない。それら特殊な
切断装置は、装置の価格が高価であったり、生産速度が
制限されたりして生産コストを引上げる。As an alternative to this, after filling a continuous lattice body such as expanded metal or continuous casting with the active material paste, instead of the covering paper, a mat-like material made of fine glass fibers that later serves as a pallet is used. A possible manufacturing method is to glue and integrate the parts and then cut them. However, in this manufacturing method, it is difficult to apply conventional mechanical cutting methods to cut the continuous lattice body integrated with the glass mat, and a very special cutting method must be used. These specialized cutting devices increase production costs due to expensive equipment and limited production speeds.
また、エキスバンド格子体にガラスマットを接着させた
ものは、切断面で極板が露出するので、このような陽陰
極板を用いて極群を形成し、電池を組立てた場合には、
前記切断部にガラスマットのはみ出し部分がなく、陽陰
極板の隔離効果が小さいので、側部の内部短絡を生じや
すく、これを防ぐべく別途側部に隔離板の挿入が必要と
なったりフスト窩になる欠点がある。In addition, when a glass mat is bonded to an expanded grid, the electrode plates are exposed at the cut surface, so if such anode and cathode plates are used to form an electrode group and a battery is assembled,
Since there is no protruding part of the glass mat in the cut section, and the isolation effect of the anode and cathode plates is small, internal short circuits are likely to occur on the sides, and to prevent this, it is necessary to insert a separate separator plate on the sides, and There are drawbacks to it.
上述の如き種々の問題点があり、エキスパンドメタルを

りなるマット状体を接着一体化する製造方法は、実用化
されていない。Due to the various problems mentioned above, a manufacturing method in which an expanded metal lattice is filled with an active material paste and a mat-like body made of fine glass fibers is bonded and integrated has not been put to practical use.

ある。Structure of the Invention The lead-acid battery of the present invention has a continuous mat-like body made of fine glass fibers with a diameter of 5 pm or less bonded to both sides of an electrode plate filled with active material paste in a continuously cast grid body. The electrode plate is cut into a certain width after being integrated, and has rod-shaped connecting parts on both sides.

特徴とするものである。Furthermore, the method for manufacturing a lead-acid battery according to the present invention includes forming a continuous mat-like body made of fine glass fibers having a diameter of 5 μm or less on both sides of an electrode plate in which a continuous casting grid is filled with an active material base. In the continuous manufacturing method, in which the continuous cast lattice bodies are bonded and integrated and then cut into a certain width, the shape of the continuously cast lattice bodies is made continuous by connecting each lattice body with thin rod-shaped connecting parts in advance, and then the rod-shaped lattice bodies are It is characterized by cutting at the connecting part.

ある。A low-antimony lead alloy or a lead-calcium alloy is melted, and a continuous cast lattice body is made by a continuous casting machine, in which the cast lattice bodies are connected by two rod-shaped connections, as shown in Fig. 2. Lead powder, It is filled with a paste-like active material made of sulfuric acid, water, etc. While continuously filling the continuous casting grid with paste, a continuous mat made of band-shaped fine glass fibers is adhered to both sides of the electrode plate immediately after filling using a roller press. In this fine glass fiber mat body, the diameter of the fine glass fibers on the surface that contacts the electrode plate is 0.8 μm on average, and the other surface is made of glass fibers with a diameter of about 19 μm. The glass fiber layer portion having an average diameter of 0.8 μm may be only the portion that adheres to and adheres to the active material. An electrode plate (FIG. 3) in which the continuous mat-like bodies are bonded and integrated is press-cut at the center of the rod-shaped connecting portion of each grid body. (A-m' and B-B' in Fig. 3 are cutting points) The cut electrode plate has rod-shaped connecting portions at the time of casting on both sides of the electrode plate, as shown in Fig. 1. The anode and cathode plates to which this fine glass fiber mat is attached are combined to form a pole group. (Fig. 4) In this case, each electrode plate must be moved and aligned, but the automatic machine applies considerable force, which may deform or damage the fine glass fiber mat on the side of the electrode plate. There is a risk of However, not only is the rod-shaped connection part convenient because it plays the role of preventing these problems, but also the glass fiber mat protrudes from the four peripheries of the electrode plate, so batteries assembled using this electrode plate can There is very little risk of causing an internal short circuit on the sides of the electrode group. Of course, the positions of the rod-shaped connections of the anode and cathode plate grid bodies should be changed in advance so that they are not the same, and when forming the electrode group, the rod-shaped connections of the #cathode plates Care must be taken to minimize the risk of internal short circuits by ensuring that the parts are not lined up in the same location.
又、微細ガラス繊維マットにより一体化された極板の切
断においても、非常に細い金属接続部分で切断するので
、切断が容易であり、プレス切断加工で充分である。Further, even when cutting an electrode plate integrated with a fine glass fiber mat, cutting is performed at a very thin metal connecting portion, so cutting is easy, and press cutting is sufficient.
本発明の鉛蓄電池は、従来電池のように極板をガラスマ
ットが別々の場合に比べて、組立ての工数が大巾に削減
できる。The lead-acid battery of the present invention can greatly reduce the number of assembly steps compared to conventional batteries in which the electrode plates are made of separate glass mats.
こ＼で極板に接続する微細ガラス繊維マットの直径を３
μｍ以下とするのは、これよりも大きい径では、ガラス
繊維マット体が極板にくっつきにくくはがれやすいため
である。Here, the diameter of the fine glass fiber mat connected to the electrode plate is 3
The reason why the diameter is .mu.m or less is that if the diameter is larger than this, the glass fiber mat will not stick to the electrode plate and will easily peel off.
