亜鉛−水銀合金粉末を電池用陰極活物質として用いたア
ルカリ電池およびその製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present Komei describes in detail the alkaline battery J3 and its manufacturing method. and its manufacturing method.
亜鉛を陰極活物質として用いたノフルカリ電池等にＪ５

導くことも種々行なわれているが、未だ完全なものでＩ
はない。J5 is used for noflukaline batteries etc. that use zinc as the cathode active material.
Since a strong alkaline electrolyte such as a 7J lithium hydroxide aqueous solution is used in the IJ, the battery must not be left between the road.This sealing of the battery is especially important when trying to miniaturize the battery. However, at the same time, battery 1+A: Hydrogen sludge generated due to corrosion of zinc during production is trapped. Therefore, during long-term storage, the scum pressure inside the battery increases, and the more completely sealed the battery, the greater the risk of explosion. As a countermeasure, one of the batteries
Although various efforts have been made to selectively guide the generated scum to the outside of the battery by devising the 14 structure, it is still not perfect.
There isn't.
そこで、亜鉛陰極活１６質の腐食そのものを防止して電
池内部のガス発生を少なくすることがｌＪｔ究され、水
銀の水素過電圧を利用した水銀含有亜鉛粉末を陰極活物
質どしで用いることが専ら行なわれている。Therefore, research has been conducted to prevent the corrosion of the zinc cathode active material itself and to reduce gas generation inside the battery, and it has become increasingly important to use mercury-containing zinc powder as the cathode active material, which utilizes the hydrogen overvoltage of mercury. It is being done.
しかしながら、今日市販されているアルカリ電池の陰極

こ（恐れが大きい。However, the cathode active materials of alkaline batteries commercially available today contain 5 to 15% mercury, which poses a danger to humans and other living organisms, and may cause environmental pollution. is large.
そこで、水銀を用いず、代わりに鉛等を添加した亜鉛電
極を用い゛Ｃガス発生を抑制りる方法も提案されている

い。Therefore, a method has been proposed in which the generation of C gas is suppressed by using a zinc electrode to which lead or the like is added instead of using mercury. However, the current situation is that such elements have a certain degree of scum generation suppressing effect, or that I and L are far from being able to replace mercury. Also, has a method been proposed in which zinc powder is immersed in an acidic solution containing mercury ions to which lead ions, mium ions, etc. have been added, and amalgamation is performed by the substitution method, while at the same time adding lead or cadmium to the zinc powder? Even with this method, it is not possible to reduce the mercury content while effectively suppressing gas generation.
本発明は、以上のような現状に鑑み、陰極活物質からの

ることを目的どづる。In view of the above-mentioned current situation, the present invention uses a cathode active material that dramatically reduces the content of mercury necessary to suppress the generation of hydrogen scum from the cathode active material, and also improves battery characteristics. The purpose is to provide an alkaline battery and its manufacturing method.

。The present Komei idea was cured for this purpose, and as a result of intensive research, Kano IG
In the shadow of +1! When the active material contains lead and/or indium in addition to mercury, mercury, lead and indium act synergistically to suppress the generation of scum,
Even if the mercury spacing is significantly reduced compared to the conventionally used cathode active material consisting of powder with a mercury content of 1 (2), compared to the case where the mercury content of lead powder is used as a cathode (Φ active material) and C is used. The present invention has been achieved by devising a method that suppresses the generation of scum, has an I+ effect, and has a battery performance effect that is equivalent to or better than that of C.

含有すればよく、それ以上配合しても効果が少ない。The conventional cathode active material consisting of simple mercury-containing zinc powder is
The negative active material used in the alkaline battery of the present invention has a mercury content of ~15% by weight.
Even if the ratio is less than 5% by weight, or even less than 1% by weight, it is possible to suppress the generation of scum to a greater extent than that of the conventional method. Of course, it is also possible to increase the mercury content and increase the C scum generation suppression function accordingly. Practically speaking, the preferable mercury content of the cathode active material is less than 5 wt. The I/J content of indium may be 0.005 to 1% by weight and should be contained in a small amount, and even if more than that is added, the effect will be small.
