０個中の内部短絡不良数及びＩＯＣ放電容量を調べたと
ころ、下表の結果が得られた。Incidentally, a conventional battery B of the same type was manufactured, using the pressure contact method according to the present invention as the current collecting method for the positive and negative electrode plates, and a conventional battery B of the same type, which collects current by welding a conventional IJ + plate. 10
When the number of internal short circuit failures and IOC discharge capacity among 0 pieces were investigated, the results shown in the table below were obtained.
上表より、本発明電池人は内部短絡が完全に防止されて
おシ、高率放電にも適していることがわかった。From the above table, it was found that the battery of the present invention completely prevented internal short circuits and was suitable for high rate discharge.
これは従来電池が正極板と負極板とを重ねて捲回しする

ド片が存在せず、極板を圧接する際に絶縁部材を介して
圧縮するので、極板の巻きズレを矯正でき内部短絡の危
険性が全くない。This is because when conventional batteries stack the positive and negative electrode plates and wind them, the winding of the electrode plates becomes misaligned. This is because a short circuit may occur between the negative electrode plate, one electrode plate and the other lead piece, etc. In contrast, in the battery of the present invention, there is no lead piece and the electrode plates are compressed through the insulating member when they are pressed together, so that the winding misalignment of the electrode plates can be corrected and there is no risk of internal short circuits.

すこともできる。Furthermore, the positive and negative electrode plates of the battery of the present invention are pressed into contact with the lid plate and the bottom of the metal container, respectively, and their contact area is larger than that of the lead pieces of conventional batteries, resulting in low contact resistance and high rate discharge. In addition, the volume of the electrode plate for each lead piece can be increased.
尚、上記正極板と負極板の構成を全く逆にしても何ら支
障はなく、本願内に含まれる。Note that there is no problem even if the configurations of the positive electrode plate and the negative electrode plate are completely reversed, and this is included within the scope of the present application.

矯正機能を有することで、極板の捲回しの際の位置決め
精度を上げる必要もなく、また、金属容器開口側の内方
突出部を設ける必要もない。According to the present invention, the positioning accuracy during winding of the electrode plate can be improved by removing the IJ-shaped piece or contact plate that collects current from both the positive and negative electrode plates, and by having the function of correcting the winding misalignment of the electrode plate using an insulating member. There is no need to raise the metal container, and there is no need to provide an inward protrusion on the opening side of the metal container.
