目的とする。[Detailed Description of the Invention] Kihatsu F3A is an improvement of a small alkaline battery, with improved corrosion resistance of the positive electrode can, which will not be destroyed by gastric juices even if accidentally swallowed by a child, and can be easily removed using a magnet. The purpose is to provide a small-sized alkaline battery that is water-resistant.
最近、ゲーム機、ゲームクオツチなどの子供向は電池応
用機器の普及に伴ない、幼児があやまって電池を飲み込
むという事故が多発している。Recently, with the spread of battery-powered devices such as game consoles and game consoles for children, there have been many accidents in which young children accidentally swallow batteries.
そして、こうした誤飲事故があった場合、できるだけ早
く電池を体内から取り出さないと電池が胃の中で破壊さ
れ、アルカリ電解液などの有害な内容物が体内に流出し
て人体に危害を及ぼすおそれがあると報じられている。If such an accidental ingestion occurs, if the battery is not removed from the body as soon as possible, the battery may be destroyed in the stomach and harmful contents such as alkaline electrolyte may leak into the body, causing harm to the human body. It is reported that there is.

願をした。In view of these circumstances, the inventors of the present invention have conducted extensive research to elucidate the mechanism by which batteries are destroyed in the stomach and find countermeasures to prevent such destruction. to be caused by being
To prevent this, the positive electrode can must have a chromium content of 28
It was discovered that it could be made of high chromium stainless steel with a weight percentage of 50% or higher, and a separate patent application was filed for this.

と１．・すいえ丁、体内からの電池の取り出しに１祭し
、磁石の先端がどうしても負極端子板側にしか届かない
ような場合には取り出しかできないという問題がある。By the way, among the high chromium stainless steels mentioned above, ferritic ones are ferromagnetic, so when a battery is removed from the body with a magnet, the positive electrode can is strongly attracted to the magnet, which is extremely convenient. Since the clad plate normally used as the negative terminal plate of alkaline batteries is made of austenitic stainless steel, which is a non-ferromagnetic material, the attraction of the magnet to the negative terminal plate is due to the outer surface of the negative terminal plate. Since only the nickel layer is made of 1C, it is strong and 1.・There is a problem with removing the battery from the body, but if the tip of the magnet can only reach the negative terminal plate side, it can only be removed.
本発明はそのような事情に鑑みてなされたものであり、

で体内から容易に取り出し得るようにしたものである。The present invention was made in view of such circumstances,
The positive electrode can is made of ferritic high chromium stainless steel with a chromium content of 2A or higher, and the negative electrode terminal is made of a copper layer (copper layer as a mating material to be placed inside the battery) and ferritic stainless steel as the matrix. By using a clad plate with a steel layer, it is possible to prevent the battery from being destroyed in the stomach even in the event of an accidental ingestion.
By making the positive electrode can and negative electrode terminal plate ferromagnetic, the battery can be easily removed from the body using a magnet.

を設けておくことが好捷しい。If these ferritic high chromium stainless steels are used in positive electrode cans, hexavalent chromium ions (Cr6+) may be eluted from the positive electrode can, causing a decline in electrical properties and potentially having an adverse effect on the human body. Therefore, in order to prevent this, it is preferable to provide a nickel layer on the inner and outer surfaces 1 of the positive electrode can.

不充分であった。When the battery obtained as described above was subjected to an adsorption test using a magnet, it was found that the positive electrode can of the battery of the example was made of ferromagnetic SUS 447J 1 plated with nickel, and the negative electrode terminal plate was also made of ferromagnetic material SUS 447J1, which was nickel plated. SUS 43 which is a magnetic material
0 as the base material, both the positive and negative electrode sides were well attracted to the magnet. On the other hand, in the battery of the comparative example, the positive electrode can was made of iron plated with nickel, so the magnetic attraction was good, but the base material of the negative electrode terminal plate was SUS 804, which was a non-ferromagnetic material. However, since only the thin nickel layer on the outer surface was ferromagnetic, its adsorption to the magnet was insufficient.

The battery was immersed in an aqueous solution containing 2f of NaCl and 24ml of 104HCI at 37°C for 24 hours, and the presence or absence of battery destruction was examined by detecting potassium ions in the artificial gastric fluid.
