蓄電池の寿命特性改善に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to improving the life characteristics of a paste type lead-acid battery having a maintenance-free function.
従来の技術
メンテナンスフリー化のために従来よりＰ ｂ −Ｃａ
Ｓｈ系鉛合金集電体が広く用いられている。Conventional technologyIn order to make maintenance free, P b -Ca
Sh-based lead alloy current collectors are widely used.
この合金系においてはＣａ含有率を高めて集電体の強度
をあげハンドリング性を確保している。In this alloy system, the Ca content is increased to increase the strength of the current collector and ensure handling properties.
発明が解決しようとする課題
集電体の合金組成中のＣａは強度を高める効果があるが
、充放電に伴う集電体の腐食によって集電体が伸びなど

集電体の合金組成中のＣａとｓｈの含有量は、Ｃａは少
ない程、またｓｈは多い程陽極板の耐久性向上に良い。Problems to be Solved by the Invention Ca in the alloy composition of the current collector has the effect of increasing strength, but corrosion of the current collector during charging and discharging causes deformation such as elongation of the current collector, causing the entire anode plate to deteriorate. It cannot be prevented from stretching or deforming. On the other hand, Sb does not particularly have the effect of increasing the strength of the current collector, but has the effect of improving the corrosion resistance of the alloy itself, suppressing elongation and deformation accompanying corrosion of the current collector, and preventing deformation of the anode plate itself. That is, regarding the content of Ca and sh in the alloy composition of the current collector, the lower the content of Ca and the higher the content of sh, the better the durability of the anode plate will be improved.
しかしこの場合集電体強度は極度に低下し生産過程や電
池として使用中において早期に変形する。However, in this case, the current collector strength is extremely reduced and deforms early during the production process or during use as a battery.
使用中の陽極板の変形を生じさせるものは、極板に対す
る加圧の不均一性や、充放電による活物質の組成変化に
伴って生じる応力および集電体の腐食による伸びである
。Deformation of the anode plate during use is caused by uneven pressure applied to the plate, stress caused by changes in the composition of the active material due to charging and discharging, and elongation due to corrosion of the current collector.
本発明は極板に対する加圧の均一化を促進するとともに
前記性の２要因の影響を低減し陰極板の変形発生時期を
遅延ならしめるものである。The present invention promotes uniformity of pressure applied to the electrode plate, reduces the effects of the above two factors, and delays the occurrence of deformation of the cathode plate.
３題を解決するための手段
集電体にペーストを充填した後、活物質保護体を当接し
そのまま加圧下で乾燥させることによって、電池に組み
込まれる迄の変形を防止する。この防止を可能とするの
は乾燥したペースト層である。Means for Solving the Three Problems After filling the current collector with paste, the active material protector is brought into contact with the current collector and dried under pressure to prevent deformation before it is assembled into a battery. It is the dry paste layer that makes it possible to prevent this.
極板を加圧伝達板を介して重ね合わせ掻板群を作成し加
圧状態で電槽に収納することにより極板の変形（波打ち
、くびれ、そり）を抑制する。Deformation (waving, constriction, warpage) of the electrode plates is suppressed by overlapping the electrode plates via a pressure transmission plate to create a group of scraped plates and storing them in a battery case under pressure.
