従来例の構成とその問題点
従来の密閉式電池の例を第１図及び第２図により説明す
る。これらは何れもリチウムを負極とした電池である。Structure of a conventional example and its problems An example of a conventional sealed battery will be explained with reference to FIGS. 1 and 2. All of these batteries use lithium as a negative electrode.

っている。この他垂直に下向きに切断することもある。1 in the figure is a steel battery case whose surface is coated with nickel.
For example, a cathode material 2 such as manganese dioxide or carbon fluoride is contained therein. Reference numeral 3 denotes a special steel sealing lid, which is dish-shaped, and up to the end thereof, in FIG. 1, it has a folded up rising part 4, and in FIG. It is 5. Alternatively, the cut may be made vertically downward.

れが適応でない場合は、封口をどのようにしても耐漏液
性をよくすることは困難である。As is clear from Fig. 1, the battery constructed in this way has good liquid-tightness, that is, the leakage resistance of the battery, due to the sealing bending angle and uniformity of the bending at the rising end of the metal case, and the dimensional accuracy of the parts. Fluidity is greatly affected. In particular, if the dimensional accuracy, shape and positional accuracy (geometrical accuracy) of the parts are not suitable, it is difficult to improve the leakage resistance no matter how the sealing is done.

及び表示」によれば「真直度とは、直線部分の幾何学的
直線からの狂いの大きさをいう」と定義されている。Purpose of the Invention The present invention provides a seal with excellent leakage resistance by keeping the true 1μ degree of the lowest end of the outer folded part of the sealing lid, or the lowest edge of the outer circumference if there is no folded part, within a certain limit among these parts. According to ``Definition and Indication of Accuracy of Shape and Position'', ``Straightness refers to the deviation of a straight part from a geometrical straight line''. It is defined as "the size of the

大きさをいい、これを０．０３ｒｒｖｎ以内としたもの
である。In the present invention, the straightness of the lowermost end of the folded part of the sealing lid or the lowermost edge of the periphery when there is no folded part is defined as the straightness of the lowermost end of the circumferential edge when the circumferential sleeve part is cut along an arbitrary line and the lower end becomes a straight line. This refers to the degree of deviation of the straight line portion from the geometrical straight line, and this is within 0.03rrvn.

第５図は折返し部を持たない封口蓋のスリーブ最下端の
真直度のわるい例を示す。Description of an Example To explain this with reference to FIG. 3, the line segment N1 connecting points A and B is deviated from the geometric straight line AB, and the magnitude of the deviation, that is, the straightness, is expressed by f. . FIG. 4 shows an example in which the straightness of the lowermost end of a sealing lid having a folded part is poor, and FIG. 5 shows an example in which the straightness of the lowermost end of a sleeve of a sealing lid without a folded part is poor.
このように、封口蓋の最下端の真直度が劣る場合、金属
ケース端縁を曲げても封口蓋最下端にかかる圧力は均一
化されず、圧力の小さいところから電解液が漏出する。As described above, when the straightness of the lowermost end of the sealing lid is poor, even if the edge of the metal case is bent, the pressure applied to the lowermost end of the sealing lid is not equalized, and the electrolyte leaks from a place where the pressure is low.
近年、機械的加工部品は、単なる寸法精度のみでなく、
形状及び位置の精度（幾何学的精度）について論議され

部最下端、又は折返し部を持たない場合はスリー ７”
最下端の真直度についてこれを０．０３ ｍｍ以内にし
ようとするものである。In recent years, mechanically processed parts require not only dimensional accuracy but also
Although the precision of shape and position (geometric precision) is often discussed, the present invention applies to the lowermost end of the outer circumferential folded part of the sealing lid, or if the sealing lid has no folded part, the three 7"
The aim is to keep the straightness of the lowest end within 0.03 mm.
このようにすることにより、封口蓋下端にかかる圧力を
均一にすることができ、電池の耐漏液性が向上する。By doing so, the pressure applied to the lower end of the sealing lid can be made uniform, and the leakage resistance of the battery is improved.
真直度の良好な封口蓋は、抜き及び絞りのプロセスを選
ぶことと、金型精度を保つことによって得られる。折返
し立上り部を有する場合は特に絞りの過程において折返
し部上端を金型で叩くことにより、最下端の真直度がよ
くなる。A sealing lid with good straightness can be obtained by selecting the punching and drawing processes and by maintaining mold precision. If the material has a folded rising portion, the straightness of the lowermost end can be improved by hitting the upper end of the folded portion with a mold during the drawing process.
真直度を０．０３ ｍｍ以内とした理由は、真直度は小
さなければ小さい方がよいことはいうまでもないが、電
池漏液テストの結果０．０３ ｍｍ以内であれば、実用
上支障がないことが判明したためである。The reason for setting the straightness to within 0.03 mm is that it goes without saying that the smaller the straightness, the better, but as a result of the battery leakage test, if it is within 0.03 mm, there is no practical problem. This is because it turned out that there was no such thing.

顕微鏡で漏液の有無を観察した。A fluorocarbon lithium battery with an outer diameter of 23mm and a height of 2.0mm was tested. The test method was to store the battery at 60°C for 1 hour and then immediately store it at -10'C for 1 hour, which was repeated for 30 consecutive days, and then the presence or absence of leakage was observed using a 10x microscope.

2020 Effects of the invention As described above, the straightness of the lowest end of the folded part of the sealing lid, and the lowest end of the periphery of the sealed lid without a folded part, is set to 0.03.
Maintaining the thickness within mm has an extremely excellent effect on the leakage resistance of the battery.
