ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to bagging used for insulating sealing of button-type alkaline manganese batteries.By using a figure-eight backing, which is different from the conventional backing shape, the present invention provides a button with excellent leakage resistance. type alkaline manganese battery.
近年の小形電子機器発展に伴って、小形、軽量。With the recent development of small electronic devices, they have become smaller and lighter.

ルカリマンガン電池が見直されて来た。There was a growing demand for high-output power supplies, and the button-type silver oxide battery met this demand. However, due to the rise in the price of silver oxide batteries due to the rise in the price of silver ingots, button-type alkaline manganese batteries using manganese dioxide as a positive electrode active material have been reconsidered.

ン型アルカリマンガン電池を提供するものである。The structural conditions of this alkaline manganese battery are almost the same as those of a silver oxide battery except for the positive electrode, and since manganese dioxide is extremely cheap at about 1/soo compared to the price of silver, it is expected that it will be used effectively in the future. Therefore, there was a need for batteries of a quality that could be used in all kinds of small electronic devices. However, like silver oxide batteries, they still have insufficient leakage resistance, and conventional L-shaped and J-shaped backings have the disadvantage that sufficient effects cannot be obtained. The present invention eliminates this drawback and provides a 1ζ button type alkaline manganese battery that has excellent leakage resistance by using a backing with a zero-shaped structure.
以下、実施例に基づき本発明の詳細な説明する。Hereinafter, the present invention will be described in detail based on Examples.

In the figure, 1 is a positive electrode can, and 2 is a positive electrode mixture consisting of manganese dioxide and graphite. Separator 32 accommodates a backing 4 having a cross-sectional shape of 8 according to the present invention. Next, along the inside of the backing 4,
An electrolyte-impregnated material 5 is inserted, and a negative electrode mixture 6 consisting of zinc hydrate powder, carboxymethyl cellulose, and sodium polyacrylate is filled. Finally, the electrode can 7 is placed over the positive electrode can 1, and the open end of the positive electrode can 1 is caulked to seal it.
第２図は、本発明に係るＵ字バッキング断面図である。FIG. 2 is a sectional view of the U-shaped backing according to the present invention.

、０．０７〜０．１５’ｖａｎの肉厚が必要である。In the figure, Dl indicates the outer wall thickness, and D2 indicates the inner wall thickness. In order to reduce the internal volume of this D2d battery, we want to make the wall thickness as thin as possible. On the other hand, in order to injection mold the shape shown in FIG. 2, a wall thickness of 0.07 to 0.15'van is required.

。For these reasons, the optimum thickness D2 of the inner side of the figure 8 backing according to the present invention is 0.07 to 8.13 mm.

のである。The reason for this is that with conventional backings, the contact area with the bottom of the electrode can is small, so the electrolyte tends to seep between the electrode can and the backing, making it difficult to prevent leakage. Since the figure 8 backing of the present invention has a long fold, the contact area of the force and force inward from the bottom of the electrode can is large 9, which has the effect of preventing the infiltration of electrolyte.

Therefore, it is ideal for use not only in electronic wristwatches that require long-term reliability, but also in other small electronic devices such as calculators and toys.
