て、円筒の高さ寸法を揃える。[Manufacturing Method of Negative Electrode Zinc Can] As is well known, the negative electrode zinc can used in the manganese battery is manufactured by the following series of steps. An appropriate trace metal described below is added to zinc ingot and dissolved. The molten zinc-based alloy is continuously cast to obtain a continuous strip. The continuously cast strip is continuously hot-rolled to obtain a plate having a predetermined thickness. A circular pellet having a predetermined size is punched out from the rolled plate. The pellets are set in a mold and impacted with a punch to form a cylinder with a bottom (impact backward extrusion method). The height of the cylinder is made uniform by cutting the opening of a zinc can that is formed into a bottomed cylinder.

In the punching process, circular pellets with a diameter of 30 mm were punched out, and in the forming process, a cylinder with a bottom having a diameter of 31.4 mm and a thickness of 0.5 mm was formed. In the height cutting process, the height of the cylinder was 53.

Cracks, cracks, burrs, etc. occur in the can, and it cannot be used as a negative electrode zinc can for batteries. It is a fundamental and essential requirement that a cylindrical can can be molded with a good yield without causing such a defect (this is referred to as processability for forming a container).

加工性（展延性）と相反する関係にある。The completed negative electrode zinc can then proceeds to the battery assembly line, the positive electrode, the separator, the electrolytic solution, etc. are stored in this can, and the positive terminal plate and the sealing gasket are fitted into the opening of the can to seal the can. To do. If the mechanical strength of the zinc can as a can is too low, the can will be deformed during and after battery assembly, causing various problems. Therefore, the zinc can after being formed needs a certain level of mechanical strength. The strength after forming the can is in a relationship contradictory to the workability (spreadability) of the above-mentioned can.

These characteristics include not only the composition of the zinc-based alloy, but also the melting temperature of the melting process in the manufacturing process, the temperature of the casting process mold, the rolling process temperature and rolling rate, the pellet punching process temperature, and the forming container process temperature. Many factors are involved, such as temperature and processing rate (these are called process factors).

However, as is well known, under the technical idea of removing harmful substances from the constituent materials of batteries as much as possible, first, the anhydrous silver was achieved, and then the non-use of cadmium was achieved. In other words, technical improvements have been made to eliminate the added metal which has been used for a long time and which has a great effect of improving the characteristics, and also does not deteriorate the performance of the battery (for example, JP-A-61-273861 and JP-B-4-30712).
