Abstract
Description
【発明の詳細な説明】 産業上の利用分野 本発明は鉛蓄電池の改良に関するものである。[Detailed description of the invention] Industrial applications The present invention relates to improvements in lead-acid batteries.
従来の技術
近年、鉛蓄電池のセパレータにポリエチレンなどを主成
分としたフィルムを袋化し、これに正極板あるいは負極
板のいずれか一方を内包する構成の鉛蓄電池が実用化さ
れた。この種のセパレータは従来の抄紙タイプのセパレ
ータに比べ、１）電気抵抗が小さいこと。BACKGROUND OF THE INVENTION In recent years, lead-acid batteries have been put into practical use in which a separator of a lead-acid battery is a bag made of a film mainly composed of polyethylene or the like, and either a positive electrode plate or a negative electrode plate is enclosed in the bag. This type of separator has 1) lower electrical resistance than conventional paper-making type separators.
２） 最大孔径が著しく小さく、セパレータ貫通ショー
トがほとんどないこと。2) The maximum pore diameter is extremely small, and there is almost no short circuit through the separator.
という利点がある。しかも袋化することにより、軟化脱
落した活物質による底部ショートがほとんど発生しない
。従ってこの技術は寿命途中での内部ショートはほとん
どなく、電池本来の寿命を全うし・、信頼性の高い電池
を供給する点で優れた技術である。There is an advantage. Moreover, by forming the bag into a bag, short circuits at the bottom due to the active material softening and falling off hardly occur. Therefore, this technology is an excellent technology in that there are almost no internal short circuits during the life of the battery, the battery's original life is fulfilled, and a highly reliable battery is provided.
発明が解決しようとする課題
しかしながら、袋に内包される極板に足が設けられてい
る場合、第２図に示すように足が′セパレータのリブの
ない薄い部分′（以下“ベース部”という）と直接接触
し、使用中にこのベース部に穴が開き、他方の極板と接
触してショートするという危険性がある。Problems to be Solved by the Invention However, when the electrode plate contained in the bag is provided with legs, the legs are attached to the 'thin part of the separator without ribs' (hereinafter referred to as the "base part") as shown in Figure 2. ), there is a risk that during use this base part will be punctured and come into contact with the other plate, causing a short circuit.
これを解決する一手段として、第３図に示すように足の
幅をセパレータのリブ間の寸法よりも大きくし、足をリ
ブと接触させる方法が提案された。しかしながらこの技
術を用いた場合でも、数本のリブで極板を支えるため、
十分な効果は得られない。As a means to solve this problem, a method has been proposed in which the width of the legs is made larger than the distance between the ribs of the separator and the legs are brought into contact with the ribs, as shown in FIG. However, even when using this technology, the electrode plate is supported by several ribs, so
Not enough effect.
課題を解決するための手段
本発明は、上記の問題点を解決するものであり、極板底
部に設ける足の幅をセパレータのリブ間の寸法よりも短
く （小さく）シ、かつ足の長さをリブの高さより短く
したものである。Means for Solving the Problems The present invention solves the above problems by making the width of the legs provided at the bottom of the electrode plate shorter (smaller) than the dimension between the ribs of the separator, and the length of the legs. is shorter than the height of the rib.
作用
これにより極板底部をセパレータに設けたすべてのリブ
と接触させ、局部的に加わる圧力を分散させ、セパレー
タ底部での破損を防止するものである。Function: This brings the bottom of the electrode plate into contact with all the ribs provided on the separator, disperses locally applied pressure, and prevents breakage at the bottom of the separator.
実施例
本発明は第１図に示すように、袋状セノくレータ１に内
包される極板２底部に設ける足３の幡をセパレータ１の
リブ４間の寸法よりも短く （小さく）シ、かつこの足
３の長さをリブ４の高さよりも短くしたものである。す
なわち足３の幅をＡ１足３の長さをＢとし、またセパレ
ータ１のリブ４間の寸法をＬ１リブ４の高さをＨとする
と、Ａ＜Ｌ
Ｂ＜Ｈ
の２つの式を同時に満足させたものである。Embodiment As shown in FIG. 1, the present invention has a structure in which the flaps of the legs 3 provided at the bottom of the electrode plate 2 contained in the bag-like senolator 1 are shorter (smaller) than the dimension between the ribs 4 of the separator 1. Moreover, the length of this leg 3 is made shorter than the height of the rib 4. In other words, if the width of the leg 3 is A1, the length of the leg 3 is B, the dimension between the ribs 4 of the separator 1 is L1, and the height of the rib 4 is H, then the two equations A<L B<H are satisfied at the same time. This is what I did.
これによって、足３はリブ４で浮かされ極板２の底部は
全てのリブ４と接触し、セパレータには局部的な圧力が
加わらないため、セパレータの底部での破損を防止する
ことかできる。As a result, the legs 3 are suspended by the ribs 4 and the bottom of the electrode plate 2 comes into contact with all the ribs 4, and no local pressure is applied to the separator, thereby preventing damage to the bottom of the separator.
特ニセバレータがポリエチレンなどを主成分とするフィ
ルムで袋状とされている場合、圧力なとの機械的強度に
弱いため、本発明の技術は極めて有効である。In particular, the technique of the present invention is extremely effective when the fake barretor is made of a bag-shaped film mainly composed of polyethylene or the like, because it is weak in mechanical strength due to pressure.
ところで、セパレータ底部に圧力が加わる原因は、正極
格子の腐食などによる極板の膨脹によるところがほとん
どであるが、負極板を袋状セパレータに内包している構
成においても、隣のセルの正極板の膨脹により負極板か
セパレータ底部に圧力を与える結果となるので、負極板
をセパレータに内包する構成においても効果がある。Incidentally, the cause of pressure being applied to the bottom of the separator is mostly due to expansion of the electrode plate due to corrosion of the positive electrode grid, but even in a configuration in which the negative electrode plate is enclosed in a bag-shaped separator, the pressure applied to the bottom of the separator is Since the expansion results in applying pressure to either the negative electrode plate or the bottom of the separator, it is also effective in a configuration in which the negative electrode plate is included in the separator.
また、格子の製法、形態については鋳造格子エキスバン
ド格子など種類を問わず効果がある。Furthermore, the method and form of the lattice are effective regardless of the type, such as a cast lattice or expanded lattice.
