【考案の詳細な説明】
本考案は、ニッケルカドミウム蓄電池等うず巻形電極群
を有する電池の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in batteries having spiral-wound electrode groups, such as nickel-cadmium storage batteries.
第１図に示すように、負極板と正極板をセパレータを介
して捲回してなるうず巻形電極群１は若干太鼓状の形状
になっている。As shown in FIG. 1, a spirally wound electrode group 1 formed by winding a negative electrode plate and a positive electrode plate with a separator in between has a slightly drum-like shape.
２はゆるみ止テープ、３は正極端子である。2 is a loosening tape, and 3 is a positive terminal.
従って、このうず巻形電極群１を電池線（陰極罐）に収
納したときには、うず巻形電極群１の外周面（負極板）
と電池線の接触面積が小さく、抵抗が大きくなって特に
高率放電特性が劣る欠点がある。Therefore, when this spiral-wound electrode group 1 is housed in a battery wire (cathode can), the outer peripheral surface (negative electrode plate) of the spiral-wound electrode group 1
The disadvantage is that the contact area between the battery wire and the battery wire is small, the resistance is large, and the high rate discharge characteristics are particularly poor.
このため、負極板と電池線を端子で溶接することが行な
われているが、溶接作業の工数が多くかかる。For this reason, the negative electrode plate and the battery wire are welded together using terminals, but the welding process requires a large number of man-hours.
本考案は、簡単な工程によって負極板と電池線の接触面
積を増し、放電特性の良好な構造の電池を提供するもの
である。The present invention increases the contact area between the negative electrode plate and the battery wire through a simple process, and provides a battery having a structure with good discharge characteristics.
即ち、本考案は第２図に示すように、太鼓状のうす巻形
電極群１を電池線４に収納したとき電池線４との間に間
隙を生ヒるうず巻形電極群１の外周面の上部および下部
に導電性ペースト５を塗布したものである。That is, as shown in FIG. A conductive paste 5 is applied to the upper and lower parts of the surface.
電池線４と接触するのがニッケルカドミウム電池の陰極
板である場合、導電性ペースト５として酸化カドミウム
のペースト状のものを使用すればよい。When the cathode plate of a nickel-cadmium battery is in contact with the battery wire 4, a cadmium oxide paste may be used as the conductive paste 5.
導電性ペースト５を塗布することにより、従来のような
うす巻形電極群１と電池線４との間隙はなくなり接触面
積が広くなる。By applying the conductive paste 5, there is no gap between the thinly wound electrode group 1 and the battery wire 4 as in the conventional case, and the contact area becomes wider.
また、ゆるみ止テープ２に導電性を付与することにより
更に導通のための面積は増える。Further, by imparting conductivity to the loosening prevention tape 2, the area for conduction is further increased.
ニッケルーカドミウム蓄電池において、陰極板と電池線
とを端子で接続した従来の電池と本考案電池の（高率放
電容量）／（５ＨＲ容量）を測定したところ前者が９２
％、後者が９３％であり、本考案電池は端子を有しない
にも拘らず有するものと同等の高率放電特性を示した。When measuring the (high rate discharge capacity)/(5HR capacity) of a conventional battery in which the cathode plate and the battery wire are connected by a terminal and the battery of the present invention in a nickel-cadmium storage battery, the former was 92
%, the latter was 93%, and although the battery of the present invention did not have a terminal, it exhibited high rate discharge characteristics equivalent to those that did.
上述のように本考案は構造が簡単で高率放電特性が優れ
ており、製造工数も低減できる点極めて実用的である。As mentioned above, the present invention has a simple structure, excellent high-rate discharge characteristics, and is extremely practical in that it can reduce the number of manufacturing steps.
第１図はうず巻形電極群の斜視図、第２図は本考案の断
面図である。
１はうず巻形電極群、２はゆるみ止テープ、３は陽極端
子、４は電池線、５は導電性ペースト。FIG. 1 is a perspective view of a spiral-wound electrode group, and FIG. 2 is a cross-sectional view of the present invention. 1 is a spiral-wound electrode group, 2 is a loosening tape, 3 is an anode terminal, 4 is a battery wire, and 5 is a conductive paste.
