, 5US430 material, wire diameter 0.1mm, 50me
sh is used. Since this type of battery is used in ultra-thin devices such as memory storage power supplies for IC cards, it is desired that the battery be as thin as possible. As a power source for IC cards, the battery thickness is 0.5mm.
The following is requested.
発明が解決しようとする課題
ところが、この扁平形電池は、例えば電池厚み０．５園

らみ、使用後には電池の厚みが約０．６ｍ１ｇになる。Problems to be Solved by the Invention However, with this flat type battery, for example, when a battery with a battery thickness of 0.5 mm is made and used by inserting it into a device, the battery part swells, and after use, the thickness of the battery becomes approximately 0.6 m/g. become.
これはＩＣカードのメモリー保持電源として扁平形電池
を組み込んで機器の母体にＩＣカードを挿入した場合、
使用の初期段階は良いが、使用するにつれてＩＣカード
が膨らんで機器の母体に挿入できなくなる。This means that when an IC card is inserted into the motherboard of a device that incorporates a flat battery as a memory storage power source for the IC card,
The IC card is fine at the initial stage of use, but as it is used, the IC card swells up and cannot be inserted into the main body of the device.
以上のように従来の扁平形電池では、電池が消耗するに
つれて電池の厚みが増加して、扁平形電池を組み込んで
いるカード状機器がメモリー読み出し等をする機器本体
に差し込み不能になる問題がある。As mentioned above, with conventional flat batteries, as the battery wears out, the thickness of the battery increases, making it impossible to insert the card-shaped device into which the flat battery is installed into the device used to read the memory. .
本発明は、このような問題点を解消するものである。The present invention solves these problems.
課題を解決するための手段
本発明は、上記問題点を解消するために正極内の金属ネ

。Means for Solving the Problems In the present invention, in order to solve the above problems, the wire diameter of the positive electrode core material 2 made of a metal net in the positive electrode is set to 0.05 to 0.07 mm.
It was made into a temple. In addition, 0.1 which is generally easy to obtain
Roll a metal net with a wire diameter of about mm, and the thickness of the net along the thickness direction of the mixture is 0.05n+m=0.07m.
m to prepare a positive electrode mixture and configure it as a battery.
作用
このように本発明は、金属ネットからなる正極芯材２の
線径を０．０５ｍｍ−０，０７ｍｍにすることにより、
電池を組み立てた直後から放電終了後までに電池の膨ら
みがなく、使用直前から使用後まで安定した電池を供給
できる。Effect As described above, the present invention provides the following effects by setting the wire diameter of the positive electrode core material 2 made of metal net to 0.05 mm to 0.07 mm.
The battery does not swell from immediately after the battery is assembled to after the end of discharge, and a stable battery can be supplied from just before use to after use.
これは、正極合剤３に金属酸化物を用いて、負極活物質
４にリチウムを用いた場合、電池の放電と共に金属酸化
物が膨らんでいく。一方。負極活物質であるリチウム４
は、電池の放電と共にリチウムイオンとしてセパレータ
１を介して正極合剤３の方に移動して、放電終了時には
リチウム４がほとんどなくなる。この時、従来の構成で
は正極合剤３の膨らみが、負極活物質であるリチウム４
の減少より大きいために電池として放電終了時に電池が
膨らむ。This is because when a metal oxide is used for the positive electrode mixture 3 and lithium is used for the negative electrode active material 4, the metal oxide expands as the battery discharges. on the other hand. Lithium 4, a negative electrode active material
As the battery is discharged, the lithium 4 moves as lithium ions through the separator 1 to the positive electrode mixture 3, and almost no lithium 4 is left at the end of the discharge. At this time, in the conventional configuration, the swelling of the positive electrode mixture 3 is caused by the lithium 4, which is the negative electrode active material.
The battery swells as the battery swells at the end of discharge as the decrease in battery is greater.
これらの現象に対して、従来構成の正極合剤３の膨らみ
状態を調べると、正極合剤３の厚み方向に対して膨らみ
が非常に大きい。一方、正極合剤３の径方向に対しては
ほとんど膨れていないここが解った。この現象について
解析してみると、金属ネットからなる正極芯材２が正極

極活物質３が膨らむのを阻止する。また、正極合剤３が
径方向に膨らむことができないため、正極合剤３の厚み
方向に膨らんでいく。従って、電池の厚み方向に対して
、正極合剤の膨らみが大きくなる。In response to these phenomena, when examining the state of swelling of the positive electrode mixture 3 of the conventional configuration, the swelling is extremely large in the thickness direction of the positive electrode mixture 3. On the other hand, it was found that the positive electrode mixture 3 hardly swelled in the radial direction. Analyzing this phenomenon, we found that since the positive electrode core material 2 made of metal net is placed in the positive electrode mixture, each wire of the metal net 2 surrounds the positive electrode mixture 3, so the diameter of the positive electrode mixture This prevents the positive electrode active material 3 from expanding in the direction. Further, since the positive electrode mixture 3 cannot expand in the radial direction, the positive electrode mixture 3 expands in the thickness direction. Therefore, the swelling of the positive electrode mixture increases in the thickness direction of the battery.
そこで本発明は、上記解析結果から正極合剤の径方向に
正極活物質３が膨脹できるように金属ネット２の線径を
細くして、正極活物質を囲む体積を小さくして正極合剤
３の径方向に対する膨脹を促進させ、逆に正極合剤３の
厚み方向への膨脹を抑制したものである。Therefore, based on the above analysis results, the present invention reduces the wire diameter of the metal net 2 so that the positive electrode active material 3 can expand in the radial direction of the positive electrode mixture, and reduces the volume surrounding the positive electrode active material. The expansion of the positive electrode mixture 3 in the radial direction is promoted, and the expansion of the positive electrode mixture 3 in the thickness direction is suppressed.
また、金属ネット２の線径は、０．１ｎｎ以上のものが
ネットとして編み易く、一般的によく使われている。し
かし、線径が０．１ｍ以下のものは製造がしにくく一般
的にあまり使われていない。また、線径を細くした場合
、金属ネット２の強度が弱くなり正極合剤３を充填した
状態で正極体から正極合剤３と共にはずれてしまう問題
がある。そこで、従来使用していた線径０．１＋ｎｍの
金属ネット２をローラーにより圧延して正極合剤３の厚
み方向のネットの厚みを０．０５ｍｎ〜０．０７ｍ１１
にして上記金属ネット２の線径を細くするものと同様に
放電後の電池膨脂を抑制することができた。この方法を
採れば、金属ネット２の強度は非常に強く正極合剤３と
共にはずれることはなくなった。Further, the wire diameter of the metal net 2 is 0.1 nn or more, which is easy to knit as a net, and is commonly used. However, wires with a diameter of 0.1 m or less are difficult to manufacture and are not generally used. Further, when the wire diameter is made thinner, the strength of the metal net 2 becomes weaker, and there is a problem that the metal net 2, filled with the positive electrode mixture 3, is separated from the positive electrode body together with the positive electrode mixture 3. Therefore, the metal net 2 with a wire diameter of 0.1+nm, which had been used conventionally, was rolled with a roller to reduce the thickness of the net in the thickness direction of the positive electrode mixture 3 to 0.05 mm to 0.07 m11.
Similarly to the case where the wire diameter of the metal net 2 is made thinner, swelling of the battery after discharge can be suppressed. By adopting this method, the strength of the metal net 2 was so strong that it did not come off together with the positive electrode mixture 3.

電後の正極体厚みが低くなっていることがわかった。From the above results, for a conventional battery with a metal net wire diameter of 0.1 m and 1M, the battery thickness after discharge is 0.5 m before discharge.
It swells from m to 0.57 mm. However, the metal wire according to the present invention has a wire diameter of 0.05 mm and 0.06 mm.
, 0.07 mra, after the end of discharge, there is almost no change in the battery thickness from 0.5 m11 before discharge, and conversely, the thickness of the battery with metal net wire diameters of 0.05 m+, 0.06 n+n+ is lower. It was also found that there is a correlation between the battery thickness and the thickness of the positive electrode body, and as the metal net wire diameter becomes thinner, the thickness of the positive electrode body after discharge becomes lower.
これらのことは、金属ネット線径を細くすることにより
正極活物質３が径方向に膨らむのを抑制する度合いが少
なくなるからである。This is because by reducing the diameter of the metal net wire, the extent to which the positive electrode active material 3 is prevented from expanding in the radial direction becomes smaller.

現象は見られなかった。Next, the metal net 2 with a wire diameter of 0.1 mm used in the above conventional battery is rolled with a roller to make the thickness of the metal net 2 0.05 m + n ~ 0.09 mm in the same manner as above. When the battery thickness was measured after discharging by assembling the mM, it was found that the thickness of the battery using the metal net 2 of 0.05 mm to 0.07 mrn was 0.5 m11 or less. In addition, this metal net 2 is 0.05m1B
The positive electrode body 3 obtained by rolling to ~0.07+ni has the aforementioned metal net wire diameter of 0.0511T1 to 0.0711I.
The strength was stronger than that of n+, and no phenomenon of chipping around the positive electrode body together with the mixture was observed.
