従来技術とその問題点
近年、ニッケルカドミウム蓄電池の高容量化のために、
活物質充填量をより多くするべく、金属繊維、発泡金属
、鋳造性金属等の多孔体マットが多く採用されている。Conventional technology and its problems In recent years, due to the increase in the capacity of nickel-cadmium storage batteries,
In order to increase the amount of active material filled, porous mats such as metal fibers, foamed metals, and castable metals are often used.
しかしながら、これらのマットは多孔体である集電用リ
ード板を接続するための平板部がない。又、複雑な表面
形状のため、活物質を充填すると表面活物質除去が難し
く、集電用リード板の溶接が困難である。このために、
この種の極板を用いた場合には、■接触式集電を採用す
るか、■予めマットに設定した集電用リード板板付位置
に、テープや樹脂を用い活物質が充填されないように保
護し、活物質充填後にこれを取り除き集電用リード板を
溶接する。又■予め金属マットにリード板を溶接してお
く方法がある。However, these mats do not have a flat plate portion to which a porous current collecting lead plate is connected. Moreover, due to the complicated surface shape, it is difficult to remove the surface active material once it is filled with active material, and it is difficult to weld the current collecting lead plate. For this,
When using this type of electrode plate, either ■ adopt a contact type current collector, or ■ protect the active material from being filled with tape or resin at the position where the current collector lead plate is attached, which is set as a mat in advance. After filling the active material, it is removed and a current collecting lead plate is welded. Another method is to weld the lead plate to the metal mat in advance.
■の場合は、極板と集電用リード板の接触抵抗が大きく
問題である。更に、積層状に電極板を組合せる場合、極
板−枚毎に接触式集電体を用いる必要がある。In case (2), the contact resistance between the electrode plate and the current collecting lead plate is a major problem. Furthermore, when combining electrode plates in a laminated manner, it is necessary to use a contact type current collector for each electrode plate.
■の場合は、製作工程が複雑になるばかりか、活物質の
浸入を充分に防ぐことができず、又樹脂等が変性して除
去が回置となり極板に不純物を残したり、極板厚みを変
えたりする。In the case of (2), not only does the manufacturing process become complicated, but it is also not possible to sufficiently prevent the infiltration of the active material, and the resin etc. is denatured and removal is done by rotation, leaving impurities on the electrode plate or reducing the thickness of the electrode plate. or change it.
■の場合は、電池の種類によって、予めリード板を取り
付けておかなければならず、極板厚みを一定にするため
のプレス工程や巻き取り工程でじゃまになり折れ曲った
り、千切れたりする欠点がある。In the case of ■, depending on the type of battery, the lead plate must be attached in advance, which may get in the way during the pressing process or winding process to make the electrode plate thickness constant, causing it to bend or tear. There is.

, 01ffl, and the porous mat is not cut by pressure compression. Further, if high-pressure compression is applied too much, the mat may be cut, greatly deformed, or curled, so the pressure must be as constant as possible in the thickness direction of the porous mat. After passing through the pressure roller, the cross section of the mat warps into a 7-shape or a U-shape. In order to prevent this, use a proofing roller to correct it flat.

Note that the adhering active material on the pressurized portion may be removed by pressing and scraping a metal plate, resin, or rubber plate.
