The present invention aims to improve leakage resistance by improving the material of metal containers in button-type sealed batteries such as silver batteries, mercury batteries, alkaline manganese batteries, and silver peroxide batteries. The button-type sealed battery has a structure as shown in FIG. 1, in which a gasket 3 between a metal container 1 and a cathode sealing plate 2 is curled inward using a sealing mold at the opening of the metal container 1. The material used for the conventional metal container 1 is rimmed steel, aluminum killed steel, silicon killed steel, etc., which has sufficient compressive strength and material strength when used as a battery. As a result, after the metal container 1 was curled inward, it was not possible to obtain the optimal compressive force to the gasket 3 due to buckling, etc., and the battery did not have the necessary and sufficient leakage resistance performance as a button-type sealed battery. I couldn't say yes. The present inventors conducted a detailed study on the relationship between leakage resistance, compressive strength, and metal impurities contained in the material, and found that the silicon content was 0.04
It has been found that silicon-killed steel with a content of ~0.08% by weight is suitable. An embodiment of the present invention will be described below. First, to measure the compressive strength of the metal container material, use an autograph to set the metal container as shown in Figure 2, apply a load from the direction indicated by W, and measure the amount of deflection of the metal container against the load. If you plot it, it will usually look like Figure 3. In this figure, the maximum compressive strength A is shown at the time of the deflection amount B, and thereafter only deformation is shown without being able to withstand the load. The test was conducted by reading this compressive strength point A as the maximum load. The materials used were rimmed steel, aluminum killed steel, and silicon killed steel, and the relationship between the silicon content (wt%) as an impurity contained in each material and the metal container and compressive strength was investigated.
The results are shown in FIG. 4, and the compressive strength changes depending on the silicon content (wt%). We also investigated the relationship between silicon content (wt%) and leakage resistance for each material, and obtained the results shown in Table 1.

なるものである。[Table] In the test, 50 G13 type button-type sealed batteries with a diameter of 11.6 mm and a height of 5.4 mm were made using metal containers with the silicon content listed above, and the batteries were heated at a temperature of 45°C and a relative humidity of 90%. The number of batteries that leaked during storage is shown. In this way, the leakage resistance performance varies markedly depending on the material, and as is clear from Figure 4, there is a correlation with the compressive strength. Improvement and stabilization of leakage resistance performance was observed when the silicon content (wt%) was 0.04% or more, but when the silicon content was 0.08%
The higher the amount, the higher the compressive strength.
When the metal container was curled inward, the sealing pressure applied not only to the curled portion 1a but also to the bottom portion 1b of the metal container, making it impossible to maintain an appropriate sealing pressure, resulting in variations in leakage resistance. As is clear from Table 1, the battery of the present invention has excellent leakage resistance and is of great industrial value.
