become. This is because when an IC card is inserted into a terminal device, etc. with a flat battery installed as a memory storage power source for the IC card, the IC card swells up as it is used and becomes difficult to remove from the terminal device. become unable.

問題がある。As mentioned above, with conventional flat batteries, the thickness of the battery increases as the battery wears out, and when a card-shaped device incorporating a flat battery reaches the end of its use, it may become impossible to insert it into the device itself. There is a problem that it may become impossible to take it out.
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.

+am, and the number of stitches is 30 to 300 meshes. Preferably, the metal net is annealed and the wires are fused together.
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を
線径が０．０２〜０．０５鯨で、目数３０〜３００メツ
シュにすることにより、電池を組み立てた直後から放電
終了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。As described above, in the present invention, the positive electrode core material 2 made of a metal net has a wire diameter of 0.02 to 0.05 mm and a mesh number of 30 to 300, so that the battery can be used immediately after assembly until the end of discharge. There is no bulge in the battery, 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電池においては、電池の放電とと
もに金属酸化物が膨らんでいく。This is because in a battery using a metal oxide for the positive electrode mixture 3 and lithium for the negative electrode active material 4, the metal oxide expands as the battery discharges.
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、放電終了後にはリチウムがほとんど
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電
池として放電終了時に電池が膨らむ。On the other hand, lithium 4, which is the negative electrode active material, moves as lithium ions through the separator 1 toward the positive electrode mixture 3 as the battery is discharged, and almost no lithium is left after the discharge ends. At this time, in the conventional configuration, the expansion of the positive electrode mixture 3 is greater than the decrease in lithium 4, which is the negative electrode active material, so that the battery swells at the end of discharge.
これらの現象に対して、従来構成の電池を調べると、正

に正極合剤の径方向に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、厚み方向
に膨らんでいく。従って、厚み方向への膨らみが非常に
大きくなる。Regarding these phenomena, when a conventionally configured battery was investigated, it was found that although the positive electrode mixture 3 hardly swelled in the radial direction, the bulge in the thickness direction of the positive electrode mixture 3 was extremely large. Analyzing this phenomenon, we found that since the positive electrode core material 2 made of a metal net is placed in the positive electrode mixture, each metal wire of the metal net 2 surrounds the positive electrode mixture 3, so that the positive electrode mixture prevents the radial expansion of the Furthermore, since the positive electrode mixture 3 cannot swell in the radial direction, it swells in the thickness direction. Therefore, the bulge in the thickness direction becomes very large.
そこで本発明は、上記解析から正極合剤の径方向の正極
活物質３が膨らむことができるように金属ネット２の線
径を細くして、正極物質を囲む体積を小さ（して正極合
剤３の厚み方向への彫版を抑制したものである。Therefore, based on the above analysis, the present invention reduces the wire diameter of the metal net 2 so that the positive electrode active material 3 in the radial direction of the positive electrode mixture can expand, thereby reducing the volume surrounding the positive electrode material. 3, the engraving in the thickness direction is suppressed.

は、ネットを編んでもほどけてしまい使用できない。In addition, this metal net 2 with a wire diameter of 0.02 to 0.05 is used in screen printing plates and is easily available, but most have mesh numbers of 300 or more. . However, the mesh of 300 or more has a problem that the aperture ratio is small and the positive electrode mixture 3 comes off from the metal net. Therefore, when considering the metal net having a small number of meshes, it is possible to retain the positive electrode active material if the number of meshes is 300 or less. Also, if the net is less than 30 meshes, it cannot be used because it will come undone even if the net is woven.

した。In addition, the above metal net, that is, wire diameter 0.02 to 0.0
For 5mm mesh with 30 to 300 meshes, if you apply the positive electrode mixture 3 onto the metal net by screen printing method (batch method), you can apply almost no force to the metal net, but if you apply the positive electrode mixture 3 onto the metal net using a continuous method, If a long length is used, force will be applied to the metal net and it will deform. Therefore, the metal net was annealed to fuse the wires together to prevent deformation.

Manganese dioxide, carbon, and a binder are kneaded on the upper surface of a separator 1 made of a propylene nonwoven fabric impregnated with an electrolytic solution containing 1 mol/1 lithium perchlorate in propylene carbonate as an organic solvent. O: 2+m, filled with 5US304 metal net 2 with 50 meshes and rolled.
A dry positive electrode body is provided, a negative electrode active material 4 made of lithium is provided on the lower surface, and the central portion is surrounded by a positive electrode terminal plate 6 made of a bulged stainless steel plate and a negative electrode terminal plate 7 made of a flat stainless steel plate, The peripheral edges of the positive terminal plate 6 and the negative terminal plate 7 were overlapped with a sealing material 5 made of polypropylene, and the peripheral edges were sealed by thermal welding to assemble the battery. Similarly, the wire diameters of the metal nets were adjusted to 0.03 mm and 0.03 mm, respectively.
The battery was assembled as 04 mm, 0.05 on, and 0.06 wn. Next, as a conventional example, the wire diameter of the metal net 2 is 0.
1++++e was assembled in the same manner. In both cases, the number of participants was 50 meshes. In addition, these batteries have a battery size of 22 wn x 29 ran and a thickness of 0.5
onm, and the dimensions of the positive electrode body are 17 m x 24 m.
, thickness 0.23 + w + 6", the volume of the positive electrode body of each battery at this time is the same, and the packing density of the positive electrode body is 2.

電池の厚みを測定した。その結果を表−１に示す。Each of the above batteries was discharged at a constant resistance of 30Ω at room temperature, and when the battery voltage reached 2.5V, the discharge was terminated and the thickness of each battery was measured. The results are shown in Table-1.
（以 下 余 白）
また、上記金属ネットの線径と同様の０．０２ａｍ、

の結果が得られた。(Margin below) In addition, the wire diameter of 0.02 am, which is the same as the wire diameter of the metal net above,
0.03+IIIw, 0.04mm, 0.05mm
Batteries with a wire diameter of 0.06 square meters and a mesh count of 300 were assembled in the same manner as above, discharged, and the thickness of each battery was measured. Regarding the battery thickness at this time, results similar to those shown in Table 1 above were obtained.
以上の結果から金属ネット線径０．１ｍｍの従来電池は
、放電終了後の電池厚みが放電前の電池厚み０．０５ｍ
ｍから０．５９ｍｍまで膨れている。しかし、本発明に

低くなっている。From the above results, for a conventional battery with a metal net wire diameter of 0.1 mm, the battery thickness after discharge is 0.05 m before discharge.
It swells from m to 0.59mm. However, the metal net wire diameter according to the present invention is 0.02 to 0.05, and the number of meshes is 50 to 50 when bleached.
In the case of 300 mesh, the battery thickness before discharge does not exceed 0.50 mm after the end of discharge, and on the contrary, in the case of the metal net wire diameter of 0.02 to 0.05 mm, the battery thickness after end of discharge is low.
また、上記金属ネット線径で目数を３００メツシュ以上

。Moreover, the number of meshes was set to 300 meshes or more using the metal net wire diameter, and the positive electrode active material was filled and rolled, but the positive electrode material came off from the metal net during rolling. This is because the positive electrode active material does not enter the openings because the metal net has a small opening ratio. On the other hand, if the mesh is less than 30, the strength of the metal net is very weak, and when the net is pulled, it deforms and cannot maintain its original shape, causing the net to unravel.
また、上記各金属ネットにおいて５０メツシュと３００
メツシュの放電後電池厚みが同様であったが、この実施
例では正極体の厚みを同じにして正極体の体積を同一に
していることから反応に関与しない金属ネットの占める
体積の少ない５０メツシュのものが電池容量の面で有利
である。In addition, in each of the above metal nets, 50 mesh and 300 mesh
Although the cell thicknesses of the meshes after discharge were the same, in this example, the thickness of the positive electrode body was the same and the volume of the positive electrode body was the same, so the 50 mesh battery had a smaller volume occupied by the metal net that did not participate in the reaction. This is advantageous in terms of battery capacity.

It was applied on a metal net of 11 x 300M, but when it was made into a long piece of several looms to increase mass production, the strength was weak (and there was a problem that the woven metal net could come off).
そこで、この金属ネット３を９００℃で焼鈍して金属線
どうしを融着して、強度を高めた。この焼鈍した金属ネ
ットを使用すると編んだ金属ネットがはずれることなく
、長尺においても可能となった。Therefore, this metal net 3 was annealed at 900° C. to fuse the metal wires together to increase its strength. By using this annealed metal net, the knitted metal net will not come off and can be made in long lengths.
