難である。Problems to be Solved by the Invention In the case of the prior art described above, as batteries become thinner, that is, for batteries with a thickness of 1.6 mm or 1 mm, weighing accuracy becomes important. This is the point. If conventional weighing accuracy is maintained, in the case of this type of battery dominated by the negative electrode, the variation in battery capacity will reach ±10 to 30%. This is an important issue when designing batteries. Furthermore, even if a very small amount of zinc powder is not uniformly distributed on the surface facing the positive electrode, there are major problems such as poor discharge utilization of zinc, changes in battery dimensions due to uneven zinc, and internal short circuits. Ta. In order to solve these problems, the following proposals have been made. One proposal is to use mesh-like zinc as the negative electrode for button-shaped alkaline primary batteries, and another proposal is to use sponge-like porous zinc. To briefly describe these proposals, both involve punching out zinc into a predetermined shape and using the frozen material as a negative electrode. The purpose of these proposals is to provide uniform button-shaped alkaline primary batteries with less variation in battery capacity by using homogeneous mesh-like zinc or sponge-like porous zinc with a large surface area. . However, these proposals still have problems as described below. That is, when mesh-like zinc or sponge-like porous zinc is frozen, the zinc becomes brittle after freezing and the frozen zinc chips or cracks when punched, resulting in an extremely large change in weight. As described above, single-mesh zinc and sponge-like porous zinc are unsuitable for this type of negative electrode-dominated battery, and it is difficult to manufacture uniform button-shaped alkaline primary batteries with little variation in capacity.

次電池を提供することを目的とする。SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems and provide a highly reliable button-type alkaline primary battery with less variation in battery capacity.

合金のラス板を負極活物質として用いるものである。Means for Solving the Problems In order to solve the above-mentioned conventional problems, the present invention uses a lath plate of an alloy consisting of zinc and 10 to 20% copper as the negative electrode active material instead of the conventional negative electrode. It is something.

配による電池容量のバラツキを防止することができる。Function The above-mentioned conventional problems can be solved by using a lath plate made of an alloy of zinc and copper, especially if the copper content is 10 to 20%. Since this copper is a material for preventing the alloy from becoming brittle after being punched and made into a material, it is necessary to contain at least 10% or more. If it is less than this,
The alloy after punching becomes brittle and cannot be prevented from chipping or cracking. On the other hand, if the copper content is 20
If it exceeds 1, the amount of zinc becomes relatively small, which is disadvantageous because the effective amount of zinc added as the negative electrode main active material decreases. Another effect of the present invention is that the filling capacity of the negative electrode can be made uniform. That is, since it is a lath plate made of an alloy of zinc and copper, a negative electrode with a uniform capacity can be formed by punching. Furthermore, after punching and forming, there is no problem of chipping or cracking of the alloy, and variations in battery capacity due to the dominance of the negative electrode can be prevented.
また、銅は良好に氷化される金属であるため、電池内部
でのガス発生もなく極めて安定したボタン形アｐカリ一
次電池用の負極となる。Further, since copper is a metal that freezes well, it becomes an extremely stable negative electrode for button-type alkali primary batteries without generating gas inside the battery.
