産業上の利用分野
本考案は放電性能を向上せしめるために、電極
の格子体材料として銅を用いた鉛蓄電池に関する
ものである。[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a lead-acid battery using copper as the electrode grid material in order to improve discharge performance.
従来技術とその問題点
一般に鉛蓄電池用の銅格子体は、通常使用され
ている鉛合金格子体に比較して、電気抵抗が極め
て小さい。このため、放電時の集電電圧降下ロス

銅格子体使用の鉛蓄電池は放電性能が非常に優れ
ており、特に高率放電や、電極が縦長となる背の
高い電池において、その効果が顕著であることが
判つている。Prior Art and Its Problems Copper grids for lead-acid batteries generally have extremely low electrical resistance compared to commonly used lead alloy grids. Therefore, the current collection voltage drop loss during discharge is small, the current density at each part of the electrode surface is made uniform, and the active substance is efficiently utilized. Therefore, it has been found that lead-acid batteries using a copper lattice have very excellent discharge performance, and this effect is particularly noticeable in high-rate discharge and tall batteries with vertically elongated electrodes.
鉛蓄電池において銅格子体を使用する場合に、
作用物質が充填される部分は通常銅板をエキスパ
ンド加工や、打抜き加工によりネツト状とする。
しかしながら電極の集電部は、最終的には鉛合金
製の端子ポールへ接続しなければならない。この
時ネツト部が端子ポールと異種金属である為に、
集電用上部親骨部の極群組立の作業性をいかに効
率良くするかが大きな問題である。 When using a copper grid in lead-acid batteries,
The part to be filled with the active substance is usually made into a net shape by expanding or punching a copper plate.
However, the current collector of the electrode must ultimately be connected to a lead alloy terminal pole. At this time, since the net part is made of a different metal than the terminal pole,
A major problem is how to improve the workability of assembling the pole group of the upper main rib for current collection.
従来この問題の解決策として、上部親骨を全て
鉛合金製とし、その一部に銅ネツト部の上端を埋
め込んだ形にして、鉛合金同志のバーニングによ

子体使用電極と同様に、組立用のクシ歯に集電耳
部の銅をセツトした後、その周囲をバーニングに
より鉛合金で覆うと同時にボールと接続する構造
などを採用していた。 Conventionally, as a solution to this problem, the upper rib was made entirely of lead alloy, the upper end of the copper net part was embedded in a part of it, and the structure was assembled by burning the lead alloy together. Similar to the lead lattice electrode used in 1995, the copper for the collector ear was set on the comb teeth for assembly, and then the surrounding area was covered with lead alloy by burning, and at the same time it was connected to the ball.
しかしながら前記の如き構造では、生産性が悪
いのでコスト面で不利となり、性能面においても
未解決な問題が残されているのが現状である。 However, the structure described above is disadvantageous in terms of cost due to poor productivity, and there are still unresolved problems in terms of performance.
即ち、前者においては、上部親骨部の電気抵抗

電時の電極巾方向における電流密度分布が均一化
しない。又上部親骨部の電圧降下ロスが大きいの
で、特に高率放電時において銅格子体本来の効果
を十分に発揮させられないという欠点があつた。 That is, in the former case, the electrical resistance of the upper rib portion is as large as that of the conventional lead grid body, so that the current density distribution in the electrode width direction during discharge is not uniform. Furthermore, since the voltage drop loss at the upper rib portion is large, there is a drawback that the original effect of the copper lattice body cannot be fully exhibited, especially during high rate discharge.
一方、後者においては、バーニングによる銅耳

撃により極板が集電用の鉛合金部から離脱すると
いう大きな欠点があつた。 On the other hand, in the latter case, the reliability of the bond between the copper ear and the lead alloy due to burning is low, the voltage drop loss at the bond is large, and the electrode plate is damaged by the lead alloy for current collection due to vibration and impact during battery use. There was a major drawback in that he had to leave the club.
考案の目的
本考案は、鉛蓄電池における高率放電特性を大

するものである。Structure of the invention That is, in order to achieve the above object, the present invention provides a lattice body for a lead-acid battery having an upper rib 1 and a copper net 2, wherein the upper rib 1 and the copper net 2 are made of copper. The upper main rib 1 is characterized in that it has a current collecting ear part 5, and a current collecting connecting lead body 4 made of lead or a lead alloy is joined to the tip thereof.
実施例の説明
以下に本考案の詳細につき、実施例により説明
する。DESCRIPTION OF EMBODIMENTS The details of the present invention will be explained below using examples.
第１図のＡは本考案による銅格子体の平面図で

大図である。 FIG. 1A is a plan view of the copper lattice according to the present invention, and B is an enlarged sectional view of the upper rib and the waist of the copper net.

を一部覆う形で接合されている。 1 is an upper rib, 2 is a copper net filled with an active substance, 3 is a lower rib, 4 is a lead body made of a lead alloy for connecting a current collector, 5 is a current collector ear, and the upper rib 1 is made of copper. A copper net 2 is connected to the lower end. In addition, a current collecting ear portion 5 provided on the upper rib 1
A lead body 4 for current collecting connection is joined to the tip of the current collecting ear portion 5 so as to partially cover the copper of the current collecting ear portion 5 .

を低下させることがないので、高率放電において
優れた性能が得られる。 In this way, in the copper lattice body according to the present invention, only the ends of the upper rib ears of the lattice body, which are the current collecting parts of the electrodes, are made of lead alloy. The electrical resistance of the upper rib is extremely small compared to the body. Therefore, the effectiveness of the copper grid in reducing voltage drop loss at the current collecting section and making the current density distribution uniform in each part of the electrode during discharge is not reduced, so excellent performance can be achieved in high rate discharge. It will be done.
又端子ポールと極板との接続が、従来の鉛格子

度不足の問題が解消でき、しかも生産性が極めて
良好となる。 In addition, the connection between the terminal pole and the electrode plate can be made by burning lead alloys together, just like the conventional lead grid. For this reason, the biggest drawback of conventional batteries that use copper grids, where the upper rib is entirely copper, is that electrical resistance increases due to poor connection between the current collecting lead alloy part of the terminal pole and the current collecting ear, and mechanical This solves the problem of insufficient connection strength, and also improves productivity.

に接合できる。 In the present invention, the copper of the upper rib 1 and the lead alloy of the lead body 4 for current collector connection are joined by setting the current collecting ear part 5 in a mold in advance, and pouring lead alloy hot water into it.
They can be easily joined by a so-called casting method, or a so-called cast-on method, in which a mold is filled with lead alloy hot water and the current collecting ears 5 of the copper grid are immersed therein.
上記の方式によれば接合部の電気抵抗及び接合

はるかに信頼性の高いものが得られる。 According to the above method, the electrical resistance and bond strength of the joint are improved compared to the conventional method using burning.
You get something much more reliable.
尚、集電接続用鉛体４を純鉛にしても良く、前
記と同じ接合方法が可能である。 Note that the lead body 4 for current collector connection may be made of pure lead, and the same joining method as described above is possible.

を採用することが可能である。 In addition, the connection between the upper main rib 1 and the copper net 2 can be achieved by processing a part of one copper plate into a net shape, and then cutting the part that is not processed into a net into a predetermined shape as the main rib. The upper rib 1 and the copper net 2 are made separately and can be easily connected by spot welding the upper end of the net portion 2 to the lower end of the upper rib 1. In either method, it is possible to employ the structure of the present invention.

ても何等の障害となるものではない。 Furthermore, in the completed lattice body, a lower rib 3 is provided at the lower end of the copper net 2, and in order to prevent copper from leaching into the electrolyte, which has a negative effect on battery performance, the lattice body is plated with lead to prevent copper from being exposed. However, the present invention does not pose any hindrance to these steps.
