産業上の利用分野
本発明は、有機電解質電池、アルカリ電池等の密閉電池
の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to improvements in sealed batteries such as organic electrolyte batteries and alkaline batteries.
従来例の構成とその問題点
電池に課せられる大きな使命、特長として、次の６点が
一般に言われている。Conventional configurations and their problems The following six points are generally said to be the major mission and features imposed on batteries.
■放電寿命、■耐漏液性能、■保存性能、■高信頼性、
■安全性。■Discharge life, ■Leakage resistance, ■Storage performance, ■High reliability,
■Safety.
上記のうち、どれ一つが欠けても十分満足な電池とは言
われない。特に■の放電寿命と■の耐漏液性能とは相対
する技術内容であるために、電池設計上、両者の中庸、
接点を把握検討して生産しているのが現状である。特に
最近のように、小形薄形化していく動向の中で、両者を
ある程度満足させて設計生産することが非常に困難とな
ってきた。例えば、電池の厚みを薄くしていく場合、電
池構成部品の一部である電池ケースの厚さが従来通シの
厚さの部品では、必然的に電池内容物充填量が少なくな
り、その結果、放電寿命が著しく悪くなる。また一方、
電池内容物充填量を、ある程度充足さす場合には、電池
ケース厚等を薄くする必要があり、同一材料で電池ケー
ス厚を薄くすれば、強度が弱くなり、電池密封度が劣下
し、耐漏液性が悪くなる。以上のように小形薄形化にな
るに伴い、上記のような放電寿命と耐漏液性との中肩点
設計が困難であった。Even if any one of the above is missing, the battery cannot be said to be fully satisfactory. In particular, since the discharge life (■) and the leakage resistance performance (■) have opposing technical contents, it is important to find a middle ground between the two in terms of battery design.
Currently, we are manufacturing after understanding and considering the contact points. Particularly in recent years, with the trend towards smaller and thinner products, it has become extremely difficult to design and produce products that satisfy both requirements to some extent. For example, when reducing the thickness of a battery, if the thickness of the battery case, which is a part of the battery component, is the same as before, the amount of battery filling will inevitably decrease, and as a result, , the discharge life becomes significantly worse. On the other hand,
In order to fill the battery contents to a certain level, it is necessary to reduce the thickness of the battery case, etc. If the battery case is made thinner with the same material, the strength will be weakened, the battery sealing degree will deteriorate, and the leakage resistance will decrease. Fluid properties deteriorate. As described above, as devices become smaller and thinner, it has become difficult to design a middle ground between discharge life and leakage resistance as described above.
発明の目的
本発明は、上記のような従来の欠点を解消し、耐漏液性
、放電寿命が共に優れ、製造の容易な密閉電池を提供す

発明の構成
本発明は、電池ケースの材質として、ニッケルを６重量

含む析出硬化系の鋼を用いるものである。Structure of the Invention The present invention uses precipitation hardening steel containing 6% by weight or more of nickel, 16% by weight or more of chromium, and a small amount of aluminum as the material for the battery case.
この構成によれば、電池ケース板厚を薄くした場合にも
、電池ケース強度は従来品とほぼ同程度あり、放電寿命
、耐漏液性能を共に満足させることが可能である。According to this configuration, even when the battery case plate thickness is reduced, the strength of the battery case is approximately the same as that of conventional products, and it is possible to satisfy both discharge life and leakage resistance.

間に大きな差異があることによる。As is clear from the table 1 above, the battery of the present invention has an electric capacity,
It can be seen that both liquid leakage characteristics are excellent. - This is because, as can be seen from Table 2, there is a large difference in tensile strength between the two materials.

業性面より、より優れたものである。Furthermore, there are two methods for manufacturing the steel used in the present invention. (1) After input treatment, hold at 760 ± 16°C for 90 minutes, and within 1 hour
Cool to below 6°C, hold for 30 minutes, return to 560±10°C
966 after holding for 90 minutes and cooling.
Hold at ±10'C for 10 minutes, air cool to room temperature, then hold at -73±6°C for 8 hours within 24 hours, and heat to 610±10°C for 6 hours.
There is a method of air cooling after holding for 0 minutes, and there is no big difference in terms of tensile strength, and there is no significant difference in terms of battery characteristics, and both are excellent. However, with method 1), when pressing the battery case, the material is hard and has little elongation, which poses a problem in terms of processing, but with method (2), the material strength is weak during pressing, making it difficult to process. The treatment after press working increases the tensile strength and brings it to a predetermined level, so it is more excellent in terms of workability.
