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
ニッケル緻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溶
接による取付は方法として次の３つが提案されている。Prior Art and its Problems The following three methods have been proposed for attaching lead terminals of a paste-type nickel electrode plate using a nickel fiber sintered body or a foamed nickel porous body as a conductive substrate by welding.
■ 基板に予めリード端子を溶接し、その後正極活物質
ペーストを充填する方法。■ A method in which lead terminals are welded to the substrate in advance and then the positive electrode active material paste is filled.
■ 正極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ド端子を溶接する方法。■ A method of filling the substrate with positive electrode active material paste, then removing the filled active material from the terminal welding area and welding the lead terminals.
■ リード端子溶接部に活物質ペーストが充顛されない
ように、基板をプレスして高ｑ！！度化するあるいは、
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な除去した
部分にリード端子を溶接する方法。■ Press the board to prevent the active material paste from filling the lead terminal welding area. ! degree or
A method in which lead terminals are welded to high-density areas or areas from which masking tape has been removed, after being covered with masking tape and filled with active material paste.
これらはいずれも電極基板の露出部とリード端子の一方
の極面をスボ７）溶接するものである。ここで■及び■
では、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けとなり、工程が複雑化さ
れ、連続生産ができない。In all of these, the exposed portion of the electrode substrate and one pole surface of the lead terminal are welded to each other with a slot 7). Here ■ and ■
In this case, the pre-welded lead terminals and masking tape interfere with filling the active material paste, complicating the process and making continuous production impossible.
又、予めリード端子を取付けているために、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 terminals are attached in advance, there is a problem in that only electrode plates of a fixed size can be manufactured.
■では電極基板とリード端子を直接的に溶接するため、
正極板の溶接部には活物質等の絶縁物が介在してはなら
ず、電極基板の企馬面を確実に露呂させておくことが不
可能である。しかし、極板内に充填された活物質を完全
に除失することは非常に困難である。活物質粒子が介在
した場合、スパークし、溶接不良を生じるという欠点を
有している。■In order to directly weld the electrode board and lead terminal,
An insulator such as an active material must not be present in the welded portion of the positive electrode plate, and it is impossible to ensure that the surface of the electrode substrate is exposed. However, it is very difficult to completely remove the active material filled in the electrode plate. If active material particles are present, sparks may occur, resulting in poor welding.
又、別の方法として、ニッケルあるいはニッケル鍍金し
たリード端子を極板にカシメ等のみで接続する提案もあ
る。Another method is to connect nickel or nickel-plated lead terminals to the electrode plate only by caulking or the like.
しかしながら、ペースト式ニッケル極板にニッケル板を

ク〜に伴ってニッケル極板の電極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、ついには電
池の内部抵抗が増大し、充放電ができな（なるという欠
点を有している。However, in a battery that uses a paste-type nickel plate connected to a nickel plate by caulking, an insulating nickel oxide film forms on the surface of the nickel plate's electrode substrate and lead terminal during the charge/discharge cycle. Eventually, the internal resistance of the battery increases, making charging and discharging impossible.
