た。Problems to be Solved by the Invention In recent years, as electronic devices have become smaller and thinner, button-shaped alkaline batteries that serve as their power sources are also required to be smaller, thinner, and with higher capacity. Ta. One way to create small, thin, and high-capacity batteries is to make the parts that make up the battery thinner. However, due to this thinning, in batteries manufactured by reducing conventional batteries to similar shapes, when the thickness of the sealing plate becomes 0.15111 or less,
In particular, the problem has been that the strength of the sealing plate is weakened, and the sealing plate is greatly deformed during sealing, resulting in a decrease in leakage resistance.
本発明は、上述のような問題点を解決し、耐漏液特性に

使用することにした。Means for Solving the Problem In order to solve this problem, the present invention provides a sealing plate with a thickness of 0.
We decided to use a three-layer integrated material of nickel, austenitic ferritic stainless steel, and copper as the sealing plate material for a button-type alkaline battery that uses a 1-0.15 m long battery.

特性に優れた高容量のボタン形アルカリ電池となる。In this way, the material of the sealing plate has been changed from the conventional three-layer integrated material of nickel, austenitic stainless steel, and copper to a three-layer integrated material of nickel, austenitic medium ferritic stainless steel, and copper. By changing to , the strength of the sealing plate is significantly increased, and even if the thickness of the sealing plate is reduced from 0°1 to 0.1, the strength is the same as that of the conventional O.20jEl sealing plate. Become. This is because austenitic ferritic stainless steel has better mechanical strength than austenitic stainless steel. As a result, in the battery of the present invention, the thickness of the sealing plate is 0% to 0.
Even with a length of 15 m, the deformation of the sealing plate during sealing is not significantly different from that of a conventional plate with a thickness of 0.2018 mm, resulting in a high-capacity button-type alkaline battery with excellent leakage resistance.

From the outside of the battery, nickel, austenitic/ferritic stainless steel (5US329JI is used in this example) , consists of a three-layer copper stopper, and also serves as a negative electrode terminal. 3 is a liquid-containing material that holds the electrolyte, 4 is a separator, 5 is a positive electrode case,
At its inner bottom, a positive electrode 6 whose main component is silver oxide has a positive fM.
It is fixedly arranged by an IJ ring 7, and the positive electrode case 6 also serves as a positive electrode terminal. 8 is a sealing packing for insulating the positive electrode and the negative electrode, and is made of synthetic resin.

I), using a sealing plate (condition I) made of a three-layer integrated copper material (plate thickness 0.10n), 20 pieces of 5R416SW were manufactured, and the leakage resistance was achieved in an environment of a temperature of 46°C and a relative humidity of 90 m. This is the result of a test and comparison.
表１より明らかなように、本発明の封口板を用いて作製
し７た電池の方が、従来の封口板を用いて作製した電池
