Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、補聴器等の電源として用いられるボタン型
空気亜鉛電池に関するものである。TECHNICAL FIELD The present invention relates to a button type zinc-air battery used as a power source for hearing aids and the like.
本発明は、亜鉛を主体とする負極活物質と電解液とか
らなり、空気中の酸素を正極活物質としてなる空気亜鉛
電池において、 上記電解液濃度及び電解液量を所定の範囲内に制限す

液特性の向上を図り、信頼性に優れた空気亜鉛電池を提
供しようとするものである。The present invention is an air zinc battery comprising a negative electrode active material containing zinc as a main component and an electrolytic solution, and oxygen in the air as a positive electrode active material, and limiting the electrolytic solution concentration and the electrolytic solution amount within a predetermined range. In this way, it is intended to provide a highly reliable zinc-air battery by increasing the discharge capacity, improving the liquid leakage resistance during discharging and storing for a long period of time.
近年、高年齢化に伴う難聴対策として補聴器の需要が
急速に伸びてきており、かかる状況から補聴器用電源電
池への要求も高まっている。In recent years, the demand for hearing aids has been rapidly increasing as a measure against hearing loss due to the aging of the population, and under such circumstances, the demand for power supply batteries for hearing aids is also increasing.
従来、上記補聴器用電源としては、水銀電池が多く用
いられている。該水銀電池は、アルカリマンガン電池に
比べ電池容量が大きく、容量当たりのコストが安価であ
ること、放電電圧が安定していること等の利点を有する
反面、補聴器用電源として使用した場合、約２週間程度
で電池交換を必要とすること、陽極活物質として用いる
水銀が公害の原因となること、水銀の比重が大きいため
例えば直径11.6mm,高さ5.4mmの大きさの電池でその重量
が約3gと比較的重量が重いこと等の問題がある。Conventionally, a mercury battery is often used as the power supply for the hearing aid. The mercury battery has advantages such as a larger battery capacity, a lower cost per capacity, and a stable discharge voltage as compared with the alkaline manganese battery, but on the other hand, when used as a power supply for a hearing aid, it has about 2 The battery needs to be replaced in about a week, mercury used as the anode active material causes pollution, and the specific gravity of mercury is large, so for example, a battery with a diameter of 11.6 mm and a height of 5.4 mm has a weight of about There is a problem that the weight is relatively heavy, 3g.
これらの問題を解決する電池として、ボタン型空気亜
鉛電池が注目されている。Button-type zinc-air batteries are drawing attention as batteries that solve these problems.
上記空気亜鉛電池は、正極活物質として空気中の酸素

けでよく、従って負極活物質内容積の増大が図れ、電池
の高容量化が可能な電池である。また、空気亜鉛電池は
放電電位が平坦で安定しており、しかも低公害性且つ軽
量化が図れる等各種の利点を有している。Since the above air zinc battery uses oxygen in the air as the positive electrode active material, it is only necessary to provide the negative electrode active material and the catalyst layer in the battery, and therefore the internal volume of the negative electrode active material can be increased and the capacity of the battery can be increased. It is a possible battery. Further, the zinc-air battery has various advantages such as a flat and stable discharge potential, low pollution, and weight reduction.
ところが、上記空気亜鉛電池は、正極罐側に空気取り

反応に伴う負極活物質の体積増加により、電解液を含有
したセパレータを空気極側に圧迫することになり、該空
気孔から上記電解液が漏出してしまうという問題が生じ
電池の信頼性を喪失させることになる。However, since the zinc-air battery is provided with air holes for taking in air on the side of the positive electrode, the negative electrode active material accompanying the discharge reaction that progresses during spontaneous discharge during discharge, after overdischarge, or during long-term storage, etc. Due to the increase in volume, the separator containing the electrolytic solution is squeezed to the air electrode side, which causes a problem that the electrolytic solution leaks from the air holes, and the reliability of the battery is lost.
そこで、本発明は上述の問題点に鑑みて提案されたも
のであって、放電容量が大きく、放電時及び長期保存時
等における耐漏液特性に優れ、信頼性に優れた空気亜鉛
電池を提供することを目的とするものである。Therefore, the present invention has been proposed in view of the above problems, and provides an air zinc battery having a large discharge capacity, excellent liquid leakage resistance during discharge and long-term storage, and excellent reliability. That is the purpose.
本発明は、上述の目的を達成するために、亜鉛を主体
とする負極活物質と電解液とからなり、空気中の酸素を

を用いるとともに、該電解液量を負極活物質1AH（アン
ペア時間）相当量に対して0.26〜0.36gとしたことを特
徴とするものである。In order to achieve the above-mentioned object, the present invention comprises a negative electrode active material mainly composed of zinc and an electrolytic solution, and in an air zinc battery in which oxygen in the air is used as a positive electrode active material, the concentration of the electrolytic solution is 32.5 to A 36.0 wt% potassium hydroxide aqueous solution is used, and the amount of the electrolytic solution is 0.26 to 0.36 g with respect to the amount of 1 AH (ampere hours) of the negative electrode active material.
ここで、上記水酸化カリウム水溶液の濃度と負極活物

電時及び長期保存時等における耐漏液特性の向上が図る
ことができるのである。Here, the concentration of the potassium hydroxide aqueous solution and the content of the electrolytic solution with respect to zinc as the negative electrode active material are important. That is, the concentration of the aqueous solution of potassium hydroxide, which is the electrolytic solution, should be 3
2.5 to 36.0% by weight, 0.26 of electrolyte solution equivalent to 1 AH of negative electrode active material
When the amount is within the range of 0.36 g, it is possible to increase the discharge capacity and to improve the liquid leakage resistance property during discharging and during long-term storage.
上記電解液濃度が32.5重量％未満では電池容量の低下

ま残存してしまい放電容量の低下を招くことになる。電
解液量が0.36g以上の場合、亜鉛量が減少し高容量化す
ることができない。If the concentration of the electrolytic solution is less than 32.5% by weight, the battery capacity will be reduced, and if it is 36.0% by weight or more, the electrolyte will leak. Regarding the amount of the electrolytic solution, when the amount of the electrolytic solution per 1 AH of the negative electrode active material is less than 0.26 g, the amount of zinc increases, but the negative electrode active material volume expands during discharge and pressurizes the positive electrode to cause a shortage of oxygen supply, Zinc, which is the negative electrode active material, remains undischarged, resulting in a decrease in discharge capacity. When the amount of the electrolytic solution is 0.36 g or more, the amount of zinc decreases and the capacity cannot be increased.
正極活物質に酸素，負極活物質に亜鉛，電解液に所定
濃度の水酸化カリウム水溶液を用い、上記負極活物質1A
H当りの上記電解液量を限定することにより、放電容量
が約10％程度増加する。The positive electrode active material is oxygen, the negative electrode active material is zinc, and the electrolytic solution is an aqueous solution of potassium hydroxide having a predetermined concentration.
By limiting the amount of the electrolyte solution per H, the discharge capacity is increased by about 10%.
また、電解液量を最適値に規制しているため、放電反
応に伴う負極活物質の膨張が生じても若しくは長期保存
においても不要な電解液がなくなり、耐漏液特性が改善
される。Further, since the amount of the electrolytic solution is regulated to the optimum value, even if the negative electrode active material expands due to the discharge reaction or the unnecessary electrolytic solution is eliminated even after long-term storage, the leakage resistance property is improved.

-Sample 4 and comparative sample 1) were prepared. Table 1 shows the electrolytic solution concentration, the amount of filled zinc, and the amount of electrolytic solution of each sample battery.

About 60 ° C, 91% relative humidity, the number of leaked liquids after being left for 40 days was examined. Table 2 shows the results.

とする亜鉛量が減少するため、高容量化することができ
なくなる。It can be seen from Table 2 and FIG. 2 that when the amount of electrolyte is less than 0.26 g / AH, the amount of zinc increases but the discharge capacity decreases. This is because the negative electrode active material expands in volume during discharge and presses the positive electrode, and oxygen supply becomes insufficient, so that the zinc, which is the negative electrode active material, remains unreacted and the capacity decreases. Further, since the amount of zinc that makes the electrolytic solution capacity 0.4 g / AH or more decreases, it becomes impossible to increase the capacity.

くいと考えられるからである。From Table 4 and FIG. 3, the electrolyte concentration shows the largest discharge capacity near 34% by weight KOH, which is 32.5 to 36% by weight.
The range of KOH is considered to be the range showing good discharge capacity. If the electrolyte concentration is 36.5 wt% KOH or more, leakage occurs, and if it is less than 32.0 wt% KOH, the discharge capacity decreases. This is because when the amount of potassium hydroxide in the surface layer of the zinc particles is around 34% by weight, it becomes easy to take the form of Zn (OH) 4 2− by coordinating with zinc ions, the discharge state is good and it is difficult to become passivated zinc. Because it is considered.

Among the discharge characteristics, the discharge capacity was 409 mAH, the flat voltage was 1.27 V, and the liquid leakage during discharge was good.

なる。As is clear from the above description, the zinc-based negative electrode active material and the electrolytic solution, in the air zinc battery in which oxygen in the air is the positive electrode active material, the concentration of 32.5 to 36.0 wt% as the electrolytic solution. While using an aqueous solution of potassium hydroxide, the amount of the electrolytic solution relative to the amount of the negative electrode active material 1AH equivalent
By limiting the amount to the range of 0.26 to 0.36 g, the discharge capacity can be increased by about 10% as compared with the conventional battery.
