産業上の利用分野
本発明は、注液即用型酸化銀−亜鉛電池の製造方法に関
するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method of manufacturing a ready-to-inject silver-zinc oxide battery.
従来の技術
近年、救難肌用その他の電源として長期間の保存に耐え
、必要時には注液すれば直ちに高電圧大容量を供給し得
る注液即用型電池が要求されている。高電圧、大容量を
供給し得る電池としては酸化銀−亜鉛電池が最も優れて
いるが、酸化銀亜ｊ９電池は負極に亜鉛活物質を使用し
ているなめ、保存期間中に水分および酸素に触れると徐
々に劣化し、電圧が低下したり、容量が減少するという
問題点を有していた。BACKGROUND OF THE INVENTION In recent years, there has been a demand for a ready-to-inject type battery that can withstand long-term storage as a power source for rescue skin and other applications, and that can immediately supply high voltage and large capacity when injected when necessary. Silver oxide-zinc oxide batteries are the best batteries that can supply high voltage and large capacity, but silver oxide J9 batteries use a zinc active material in the negative electrode, so they are susceptible to moisture and oxygen during storage. When touched, it gradually deteriorates, causing problems such as a drop in voltage and a decrease in capacity.
このため従来、製造方法としては例えば保存期間中の電
池の劣化を考慮し劣化分を必要容量に上のせして製造す
る方法、あるいは完成電池の保存期間中の周囲環境を厳
しく定める方法、電池製造条件を厳しく制限する方法等
が採用されている。For this reason, conventional manufacturing methods include, for example, a method in which the deterioration of the battery during the storage period is considered and the amount of deterioration is added to the required capacity, or a method in which the surrounding environment of the completed battery is strictly determined during the storage period. Methods such as severely restricting conditions are being adopted.
発明が解決しようとする課題
しかしながら前述のように電池の劣化分を上のせして製
造したり、電池保存期間中の周囲環境を厳しく制限する
方法には以下のような問題点があった。Problems to be Solved by the Invention However, as described above, the method of manufacturing batteries by increasing the deterioration of the battery or severely restricting the surrounding environment during the storage period of the battery has the following problems.
■考慮した電池の劣化分を越えて電池が劣化し所定の性
能を発揮し得ない状態になる可能性がある。■There is a possibility that the battery will deteriorate beyond the amount of battery deterioration that has been taken into account, and will not be able to exhibit the desired performance.
■電池の劣化分を考慮し劣化分を上のせして製造するた
め、電池の重量および容積が大きくなる。■The weight and volume of the battery increases because the battery is manufactured by taking into account the deterioration of the battery and adding up the deterioration.
■電池保存期間中の周囲環境を厳しく制限することによ
り保存場所が限られる。又保存設備も必要となる。■Storage locations are limited by severely restricting the surrounding environment during battery storage. Storage equipment will also be required.
よって保存中の電池の劣化を防止するためのより好適な
手段が求められていた。Therefore, there has been a need for a more suitable means for preventing battery deterioration during storage.
課題を解決するための手段
本発明は、注液即用型酸化銀−亜鉛電池の製造方法にお
いて、極板を組み込んだ電池を真空乾燥し、真空乾燥終
了後電池ケース内を常圧復帰させる時に不活性ガスを電
池内に封入し、密栓を取り付けて密封することを特徴と
する。Means for Solving the Problems The present invention provides a method for manufacturing a ready-to-inject silver-zinc oxide battery, in which a battery incorporating an electrode plate is vacuum-dried, and the inside of the battery case is returned to normal pressure after vacuum drying. The feature is that an inert gas is sealed inside the battery and a seal is attached to seal it.
作用
完成した酸化銀−亜鉛電池を真空乾燥し、併せて不活性
ガスを電池内に封入することにより負極活物質の劣化を
防止することができる。ただ単に密栓を取り付けるのみ
でも電池外部からの新たな水分や、酸素の供給を遮断で
きるため、若干の劣化防止効果をあげることができるが
、この場合ケース内の水分および酸素が負極板に反応吸
収されるため、ケース内が減圧状態となりケースの変形
を引き起こす。したがって密栓取り付けのみでなく真空
乾燥後不活性ガスの封入が必要である。Function Deterioration of the negative electrode active material can be prevented by vacuum drying the completed silver-zinc oxide battery and simultaneously sealing an inert gas into the battery. Simply installing a seal plug can cut off the supply of new moisture and oxygen from outside the battery, which can have a slight deterioration prevention effect, but in this case, the moisture and oxygen inside the case will react and be absorbed by the negative electrode plate. As a result, the inside of the case becomes depressurized, causing deformation of the case. Therefore, it is necessary not only to install a seal but also to fill in an inert gas after vacuum drying.
実施例 以下本発明を好適な実施例を用いて説明する。Example The present invention will be explained below using preferred embodiments.

After drying, return the internal pressure to normal pressure. Dry inert gas 4
For example, by using dry nitrogen gas, the inside of the battery is filled with inert gas, and when the battery is removed from the vacuum dryer, the inert gas 4 inside the battery is sealed with a seal plug 2 and an O-ring 3.
