【発明の詳細な説明】
（イ）技術分野
本発明は、水素カス発生量の少ない電池用亜鉛合金に関
するものである。DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field The present invention relates to a zinc alloy for batteries that generates less hydrogen scum.
（ロ）従来技術
従来、アルカリ乾電池等の電池の負極材として亜鉛合金
が用いられているが、電池の使用時や保存中の水素ガス

、これら電池を使用する高価な機器の損傷を引起すので
、水素ガス発生量を低減させることが重要な問題となっ
ている。(B) Conventional technology Conventionally, zinc alloys have been used as negative electrode materials for batteries such as alkaline dry batteries, but a large amount of hydrogen gas is generated during battery use and storage, and as a result, electrolyte often leaks from the batteries. This causes damage to expensive equipment that uses these batteries, so reducing the amount of hydrogen gas generated has become an important issue.
（ハ）発明の開示 本発明は、上記の問題を解決したもので、鉛。(c) Disclosure of the invention The present invention solves the above problem.
ガリウム、アルミニウム及びインジウムを含有しアマル
ガム化されてなる電池用亜鉛合金に関するものである。This invention relates to an amalgamated zinc alloy for batteries containing gallium, aluminum and indium.
本発明の亜鉛合金における鉛含有祉は０．０１〜０．５
重ψ％、またガリウム、アルミニウム及びインジウムの
含有量はそれぞれ０．００３〜０．２屯９％の範囲が好
ましく、上記の下限値未満では水素ガス発生の抑制効果
が不充分であり、また上記の上限値を越えると効果が飽
和したり、水素ガス発生の抑制効果が劣化してしまう。The lead content in the zinc alloy of the present invention is 0.01 to 0.5
The content of gallium, aluminum, and indium is preferably in the range of 0.003 to 0.2 ton 9%, and below the above lower limit, the hydrogen gas generation suppressing effect is insufficient, and the above If the upper limit of is exceeded, the effect will be saturated or the hydrogen gas generation suppressing effect will deteriorate.
また、鉛、ガリウム、アルミニウムおよびインジウムの
いずれか一成分でも欠くと、所定の効果が発揮できない
。Furthermore, if any one of lead, gallium, aluminum, and indium is missing, the desired effect cannot be achieved.
なお、水銀は０．５重量％未満ではＨ２ガス発生清が思
慮に増加し、３．０重着％を越えるとＨ２ガス発生の抑
制効果が飽和してしまう。If mercury is less than 0.5% by weight, the amount of H2 gas generated increases unnecessarily, and if it exceeds 3.0% by weight, the effect of suppressing H2 gas generation is saturated.
