拡大し、今後一層の成長が見込まれている。2. Description of the Related Art In recent years, environmental problems have been attracting attention, and there has been a particular concern about the impact of mercury disposal on the environment. Under these circumstances, the button-type air battery has been developed as an alternative power source for mercury batteries, and because it has the advantages of low mercury, environmental friendliness, large electric capacity, and light weight, it can be used as a power source for hearing aids. Its demand is growing rapidly, mainly. Also, with the development of large-capacity types and stacked batteries,
New applications such as power supplies for pagers and power supplies for medical devices have expanded, and further growth is expected in the future.

空気中の酸素を電池内に取り入れている。FIG. 4 shows a sectional view of a button type air battery.
As shown in FIG. 4, an air intake hole 2 is provided on the bottom surface of the positive electrode case 1, and oxygen in the air, which is the positive electrode active material, is taken into the battery through this hole.
【０００４】しかし、空気取り入れ孔２を通って酸素だ
けでなく他の気体も移動するため、このことにより電池
特性が低下することがあった。However, not only oxygen but also other gases move through the air intake hole 2, which sometimes deteriorates the battery characteristics.

水酸化カリウムと反応して炭酸塩を生じ電解液が劣化す
ることにより、電池の放電特性が低下していた。That is, the water in the electrolytic solution becomes vapor from the air intake hole to evaporate and the electrolytic solution decreases, or carbon dioxide in the air enters from the air intake port and reacts with potassium hydroxide in the electrolytic solution. As a result, a carbonate is generated to deteriorate the electrolytic solution, which deteriorates the discharge characteristics of the battery.
【０００６】このため、空気電池を使用前に保存してお
く際には空気取り入れ孔をシール材で封して、孔から気
体が出入りしないようにしていた。Therefore, when the air battery is stored before use, the air intake hole is sealed with a sealing material to prevent gas from entering and exiting through the hole.

ことがあった。However, in a laminated air battery in which a plurality of button type air batteries are stacked and housed in a resin case, the air intake hole of each button type air battery cannot be sealed, so that the resin case is not sealed. In some cases, air flowed in through the air intake slits or the gap between the positive and negative terminals and the resin case, and entered into each button-type air battery.

た。For this reason, when the battery is stored before use, as shown in FIG.
As shown in (A) and (B), the periphery of the resin case is hermetically packaged with a packaging body 10 such as an aluminum foil, and the bag-shaped packaging body is broken at the time of use to take out the laminated air battery.

た。However, in an air battery, hydrogen gas may be generated from the zinc of the negative electrode, and this hydrogen gas leaks to the outside of each button type air battery to store the battery. Sometimes expands, and the package may be easily torn by an external impact. In addition, when abnormal, the degree of expansion of the package rapidly increases, and the bonded portion of the opening of the package or the package itself may be broken.
