性能が低下していた。Conventional insulating backings for sealed batteries using alkaline electrolytes have been formed by punching or injection molding polyamide resins such as nylon 6, 11, 12, 66°, and 610. However, although the above-mentioned polyamide resin fully satisfied (1) chemical resistance, it did not fully satisfy (2) mechanical strength or (3) stability of dimensions and physical properties. Therefore, due to the lack of strength of the insulating backing, the insulating backing protrudes from between the battery case and the sealing plate when the battery is sealed, and the insulating backing protrudes between the battery case and the sealing plate.
The insulating backing existed in a low-density state, reducing the leakage resistance of the battery.

定化の問題となっていた。In addition, the dimensions and physical properties of the insulating backing are unstable, causing defects in the battery assembly process and posing a problem in stabilizing battery quality.

Although the insulating backing has stable physical properties such as dimensions and mechanical strength, its tensile yield point strength is low, so the insulating backing protrudes from between the battery case 7 and the sealing plate 1 when the battery is sealed, and the battery case 7 and the sealing Between plate 1, the insulating backing was present in a low density state. Therefore, there is a drawback that the leakage resistance of the battery is lowered, which leads to deterioration of the battery characteristics.
