％性に悪影響を与える位犬きくなることを見出した。On the other hand, silver oxide (■) (mugO) is silver oxide (1) (Agl
It is known that silver oxide (Ago) with a content of less than 98% is known to adhere or not adhere to carbon II roots compared to silver oxide (Ago). II)
It has been found that the content of carbonate radicals in commercialized silver increases to the extent that it has a negative effect on the percentage properties of T-pond.
酸化銀（ｎ）でめるにもかかわらず炭酸根を含有する理
由は、酸化銀ＯＤ中に極〈僅少菫の酸化銀（１）が含Ｍ
されており、この酸化銀（１）が炭酸根を吸着もしくは
付着するのでめる。The reason why it contains carbonate radicals even though it is made of silver oxide (n) is that silver oxide OD contains very little violet silver oxide (1).
This silver oxide (1) adsorbs or adheres to carbonate radicals.

A silver peroxide battery using a positive electrode mixture mainly composed of the following had the disadvantage of poor electrical properties, discharge valleys, and electrical properties after storage.

欠点がめった。For this reason, conventional silver oxide (Cm) has the drawback of self-decomposing in an alkaline solution and reducing the electric valley m as silver oxide (11). In addition, the #l gas generated by the decomposition of silver oxide (u) oxidizes the separator, causing the separator to become brittle and its function as a separator to deteriorate.
The disadvantage that ta self-discharge is promoted is rare. In addition, the Sunki gas generated at the positive electrode diffuses and permeates through the separator to the negative electrode, oxidizes the zinc, and increases the electrical capacity of the zinc.
There were few drawbacks that made it worse. Furthermore, when this phenomenon of shelling of zinc accelerates, the surface of zinc is covered with a passive film such as zinc oxide, and even though VC still has unreacted zinc remaining as a battery active material, The drawback is that the discharge stops.

漏出を促進する欠点を有していた。In addition, because conventional silver oxide (11) easily decomposes in alkaline solution and becomes unstable, batteries using this silver oxide (11) gradually accumulate K111 elementary gas in the pond. However, when the internal pressure of the battery is low, the alkaline electrolyte has the disadvantage of promoting leakage to the outside.

は＃？！は同等でめるが、３ケ月後での低ｆＭ脅性は低
下している。As is clear from the 1st &, when no stabilizer is added during stratification*(1), compared to when a stabilizer is added during coagulation*(1). Therefore, the initial low temperature characteristics are the same as #?!, but the low fM threat after 3 months has decreased.
さらに、放電容量については、６０℃、４０日後の保存
容量が小さくなっている。すなわち、電池の自己放電率
が大きくなっている。Furthermore, regarding the discharge capacity, the storage capacity after 40 days at 60°C is small. That is, the self-discharge rate of the battery is increasing.

約５倍多くなっている。In addition, regarding leakage, compared to stabilizer,
Approximately 5 times more.
この安定化剤の添加のなｉ酸化銀（１）を用いた電池の
特性、性能が悪い塩山は、安定化剤を含Ｍしない酸化銀
口りはアルカリ電解ｉｉｌ＆ｃ接触すると徐々に分解し
ていくことによる。The characteristics and performance of batteries using silver oxide (1) without the addition of this stabilizer are poor, and silver oxide batteries that do not contain a stabilizer gradually decompose when contacted with alkaline electrolysis. It depends.

一方、安定化剤を含有した酸化銀（［１）を用いた電池
は、低温特性、ｉ電装置、漏液発生単のいづれの特性に
おいても優れていることがわかる。On the other hand, it can be seen that the battery using silver oxide containing a stabilizer ([1]) is excellent in all of the characteristics of low temperature characteristics, i-electronic device, and leakage.
この理由は、噛化銀（ＩＩ）に含有している安定化剤の
効果による。The reason for this is due to the effect of the stabilizer contained in silver (II) bitide.

ものと推定される。Although the reaction mechanism for stabilizing silver (II) has not been elucidated in detail, the stabilizer compound, which is a metal compound, is eluted by alkaline electrolysis @VC, and these ions of the metal element are converted into silver oxide ( It is presumed that by acting on II), cheaper electricity is achieved.
また、ＡｇＱ 含有量によって、安定化剤の有無にかか
わらず、低温特性、放電容量が影Ｉ１１を受ける。Furthermore, the low temperature characteristics and discharge capacity are affected by the AgQ content, regardless of the presence or absence of a stabilizer.
第１表から明らかな様に、Ａｇｏ 含有量が９７．＾
チ以下では低１％性、放電容量の各特性が悪く、一方、
９ａＯ％以上ではいずれの特性共に良い結果を得ている
。As is clear from Table 1, the Ago content is 97. ^
Below 10%, the characteristics of low 1% property and discharge capacity are poor; on the other hand,
At 9aO% or more, good results were obtained for all properties.

いては、酷化銀（１）中に極〈微少量含有している鰺化
銀（１）が吸収もしくは吸着する炭酸根の電池特性に及
ぼす彩管が無視できないことによる。The reason for this is that when the Ago content is 97.5 ts or less, the effect of carbonate radicals absorbed or adsorbed by the very small amount of silver ferrite (1) in the aged silver (1) on the battery characteristics is reduced. This is because the tube cannot be ignored.
一方、９ａＯｅｌｂ以上のＡｇＯ含有量であれば、長期
間においてけ徐々に炭酸ガスを吸着したり、吸収したシ
すると思われるが、実用的には十分使用が可能である。On the other hand, if the AgO content is 9 aOelb or more, carbon dioxide is likely to be gradually adsorbed or absorbed over a long period of time, but it is still usable for practical use.
