産業上の利用分野
本発明は銅を集電用格子体に用いた鉛蓄電池用極板に関
するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electrode plate for a lead-acid battery using copper as a current collecting grid.
従来の技術
従来、背の高い大形鉛蓄電池において１鉛または鉛−錫
系合金メツキした鉛格子体を用いた鉛蓄電池用極板が用
いられていた。BACKGROUND OF THE INVENTION Conventionally, in tall large lead-acid batteries, electrode plates for lead-acid batteries using a lead lattice plated with 1-lead or a lead-tin alloy have been used.
発明が解決しようとする課題
鉛蓄電池の集電用格子体には、一般に鉛合金が用いられ
ている。Problems to be Solved by the Invention Lead alloys are generally used for current collection grids of lead-acid batteries.
鉛合金は電気抵抗が約２１ｐΩ−傷とかなり高く、また
比重も約１１とかなり重いため、重量効率が悪く、且つ
大電流で放電すると格子の抵抗によるオーミックな抵抗
分極が大きくなって、放電電圧の低下が増加するという
欠点がある。Lead alloy has a fairly high electrical resistance of about 21 pΩ-flaws and a fairly heavy specific gravity of about 11, so it has poor weight efficiency, and when discharging at a large current, the ohmic resistance polarization due to the resistance of the grid increases, causing the discharge voltage to increase. The disadvantage is that the decrease in
更に極板の高さが増した場合には、この格子の電気抵抗
の電池性能に与える影響が大きくなり、背の高い極板を
充放電すると電流耳の設けられている極板上部のみが主
に充放電反応に関与し、下部は利用されないので背の高
い大形鉛蓄電池は寮用には向かなかった。Furthermore, if the height of the electrode plate increases, the electrical resistance of this grid will have a greater effect on battery performance, and when charging and discharging a tall electrode plate, only the upper part of the electrode plate where the ears are provided will be the main source of current. Tall, large lead-acid batteries are not suitable for dormitory use because they are involved in the charging and discharging reactions, and the lower part is not used.
これを改善するべく、銅のように鉛合金よりも電気伝導
のよい金属を格子に用いる提案があり、銅エキスバンド
格子体を用いた極板が用いられている。In order to improve this, there has been a proposal to use a metal such as copper, which has better electrical conductivity than a lead alloy, for the grid, and electrode plates using expanded copper grid bodies have been used.
銅格子体を用いる場合、銅が電池の電解液中に溶出し、
自己放電の増加、容量低下、充電効率の悪化等を引き起
こすために鉛または鉛−錫系合金のメツキが施される。When using a copper grid, copper is eluted into the battery electrolyte,
Plating with lead or a lead-tin alloy is applied to increase self-discharge, decrease capacity, and deteriorate charging efficiency.
しかしながら、鉛メツキが柔らかいこと又、後工程の練
塗および化成において、特に極板側部が傷付きこのため
に、銅が露出し、前記の問題を生じた。However, the lead plating was soft, and during the post-coating and chemical conversion processes, the sides of the electrode plate in particular were damaged, which exposed the copper, resulting in the above-mentioned problem.
又、エキスバンド格子体では、側部が矩形状になってお
り、側部に付着した活物質が電池使用中に脱落し、スポ
ンジ状となり短絡を生じて早期に電池寿命が尽きること
があった。In addition, since the sides of the expanded lattice are rectangular, the active material adhering to the sides may fall off during battery use, forming a spongy shape, causing short circuits and prematurely ending the battery's life. .
これを防ぐべく、側部に付着した活物質を後工程で取り
除くことも実施されているが、工数を要すこと、及びメ
ツキを傷付は銅を露出させる等の間層点があった。In order to prevent this, the active material adhering to the sides has been removed in a post-process, but this requires a lot of man-hours and has the disadvantage of damaging the plating and exposing the copper.
本発明は、生産性、放電々田特性及び重量効率に優れた
鉛蓄電池月極板を提供することを目的とする。An object of the present invention is to provide a monthly electrode plate for a lead-acid battery that is excellent in productivity, discharge characteristics, and weight efficiency.

Solder plating was performed, and then lead plating was performed. Washing,
A dried and lead-plated copper expanded lattice body was obtained.
この格子体に鉛合金集電体を鋳造により接合した。A lead alloy current collector was joined to this grid by casting.

明の鉛蓄電池用極板を得た。Next, attach the lower connecting body made of synthetic resin or lead alloy,
Further, a pre-formed lead alloy protector was attached to the side part by adhesion with lead-tin solder via the protrusion. This lattice body was filled with a negative electrode active material using a conventional manufacturing method and chemically formed to obtain an electrode plate for a lead-acid battery according to the present invention.
尚、銅エキスパンドメタルに予め側部保護体を接着後、
鉛メツキを行ない、極板耳部の接合、下部連結体の取り
付けをしてもよい。In addition, after adhering the side protector to the copper expanded metal in advance,
Lead plating may be performed to join the electrode plate ears and attach the lower connector.
又、銅エキスパンドメタルに極板耳部を接合して、側部
保護体を接着しメツキして下部連結体を取り付けること
も可能であり、種々な方法がとれる。It is also possible to attach the lower connecting body by joining the electrode plate ears to the copper expanded metal, gluing and plating the side protectors, and various methods can be used.
本発明による極板は、側部に格子体の厚さよりも大きく

覆されているため、充電、放電により鉛メツキ部が反応

出することもない。Since the electrode plate according to the present invention is provided with a protector larger than the thickness of the lattice on the side, especially when filling the negative electrode active material,
The expanded metal's lead plating will not be damaged and the copper will not be exposed. In addition, since the electrode plate of the present invention can be filled with active material based on the side protector, the grid body is covered with the active material, so the lead-plated part becomes difficult to react due to charging and discharging. The lead plating is not destroyed and the copper is not exposed while the battery is in use.
又、活物質充填が保護体を基準にして生産できるので、
生産性が大巾をこ向上した。In addition, since active material filling can be produced based on the protector,
Productivity has improved dramatically.
さらに銅を格子体としているので、放電々田特性・重量
効率に優れている。Furthermore, since the grid is made of copper, it has excellent discharge characteristics and weight efficiency.
尚、上記実施例では極板の側部全面に保護体を設けたが
