This invention relates to a zinc-alkaline battery which is used as a negative electrode active material for batteries.

う。(Background of the Invention) In alkaline batteries and the like that use zinc as a negative electrode active material, the batteries must be sealed tightly because a strong alkaline electrolyte such as an aqueous potassium hydroxide solution is used. This sealing of the battery is particularly important when attempting to miniaturize the battery, but it also traps hydrogen gas generated due to corrosion of zinc during battery storage. Therefore, during long-term storage, the gas pressure inside the battery increases, and the more completely the battery is sealed, the greater the risk of explosion.
その対策として、負極活物質である亜鉛の腐食を防止し

発が強く期待されるようになってきた。As a countermeasure, research has been conducted to prevent corrosion of zinc, which is an active material for the negative electrode, and to reduce the generation of hydrogen gas inside the battery. It is being done. For this reason, the negative electrode active materials of alkaline batteries commercially available today are 5 to io

。Therefore, various proposals have been made regarding zinc alloy powders in which various metals are added to zinc in order to reduce the mercury content in batteries. For example, there is a zinc alloy powder made by adding lead to zinc, or a zinc alloy powder made by the present inventors by adding lead and indium to zinc (Japanese Unexamined Patent Publication No. 181266/1983). However, although these zinc alloy powders have a certain degree of gas generation suppressing effect, it is still not sufficient.

It was discovered that by adding these elements, due to the synergistic effect of these additive elements, the amount of hydrogen gas generated was further reduced than that of conventional low-rate zinc alloy powders, and a zinc-alkaline battery with excellent discharge performance could be obtained. We have arrived at the present invention.

A zinc alloy to which a specific amount of one or more selected from strontium and magnesium is added is used as a negative electrode active material as it is, or used as a negative electrode active material after the zinc alloy is made into a hydrogen atom. The mercury content in the case of oxidation is smaller than the mercury content of conventional negative electrode active materials, that is, 5.0% by weight.
However, in consideration of lowering the filtration rate and reducing pollution, it is 3.0% by weight or less. Further, even if the content is as small as around 1.0% by weight or less, it is possible to suppress gas generation. In particular, in air batteries equipped with an exhaust mechanism, zinc-alkaline batteries equipped with a hydrogen absorption mechanism, etc., the permissible amount of hydrogen gas generated is relatively large, so when applying the present invention to such batteries, 1. Zinc alloys with a low or non-grading rate of 0% by weight or less are preferably used as the negative electrode active material.
