産業上の利用分野
本発明はアルカリ蓄電池用ニッケル極板の製造法に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for manufacturing nickel electrode plates for alkaline storage batteries.
従来技術とその問題点
ニッケル繊維焼結体あるいは発泡ニッケル多孔体を導電
性基板とするペースト式ニッケル極板のリード端子の形
成方法として種々の提案がなされている。Prior Art and its Problems Various proposals have been made as methods for forming lead terminals for paste-type nickel electrode plates using nickel fiber sintered bodies or foamed nickel porous bodies as conductive substrates.
基板に予めリード端子を溶接し、その後水酸化ニッケル
活物質ペーストを充填する方法や、リード端子溶接部に
活物質ペーストが充填されないように、基板をプレスし
て高密度化するが、あるいはマスキングテープにより被
覆し、活物質ペーストを充填した後、高密度部あるいは
マスキングテープを除去した部分にリード端子を溶接す
る方法がある。There is a method of welding the lead terminals to the board in advance and then filling it with nickel hydroxide active material paste, or pressing the board to make it denser so that the active material paste does not fill the welded part of the lead terminals, or masking tape. There is a method in which lead terminals are welded to the high-density area or the area from which the masking tape has been removed, after coating with active material paste and filling the active material paste.
しかし、予め溶接されたリード端子やマスキングテープ
が活物質ペーストの充填時の妨げとなり、工程が複雑化
され連続生産ができず生産性が悪い。However, the pre-welded lead terminals and masking tape interfere with the filling of the active material paste, complicating the process, making continuous production impossible, and resulting in poor productivity.
又、予めリード端子位置が決まっているので、決まった
サイズの極板しか製造できないという問題点を有してい
る。Furthermore, since the lead terminal positions are determined in advance, there is a problem in that only electrode plates of a determined size can be manufactured.
別の方法として、活物質ペーストを基板に充填した後、
端子溶接部の充填活物質を除去してリート端子を溶接す
る方法がある。Alternatively, after filling the active material paste into the substrate,
There is a method of removing the filling active material in the terminal welding part and welding the REET terminal.
しかしこの方法においては、極板基板とり−ド端子を直
接溶接するため、溶接部分には活物質等の絶縁物が介在
してはならない。しかしながら、基板の金属面を確実に
露出させることは不可能である。極板内に一度充填され
た活物質を完全に除去することば、非常に困難であり、
活物質粒子が介在した場合、スボント溶接時にスパーク
し、溶接不良となる。However, in this method, since the electrode terminals of the electrode plate and the substrate are directly welded, no insulating material such as active material should be present in the welded portion. However, it is impossible to reliably expose the metal surface of the substrate. It is extremely difficult to completely remove the active material once filled into the electrode plate.
If active material particles are present, sparks will occur during spont welding, resulting in poor welding.
又、他の方法としてリード端子を極板にかしめにより接
続する提案もある。しかしながら、かしめにより接続し

クルに伴ってニッケル極板の基板とリード端子の表面に
絶縁性のニッケル酸化被膜が形成され、電池の内部抵抗
が増大しついには充放電ができなくなるという欠点があ
る。Another method is to connect the lead terminal to the electrode plate by caulking. However, in batteries that use paste-type nickel plates connected by caulking, an insulating nickel oxide film is formed on the surface of the nickel plate substrate and lead terminals during the charge/discharge cycle, increasing the internal resistance of the battery. The drawback is that eventually charging and discharging becomes impossible.
