とすれば、発電要素を薄くシなければならず、電池容量
が小さくなる欠点があった。In conventional batteries, a power generation element is covered with a synthetic resin film, and a current collector terminal is arranged on the inner surface of the synthetic resin film and extends to the outside. Since this conventional battery uses a synthetic resin film and a current collector terminal stacked on top of each other, if the thickness of the battery is kept constant, the power generation element must be made thinner, which has the disadvantage of reducing the battery capacity.
また、従来の電池は集電体を兼ねた封口板を用いている

れる平板型電池を提供することができた。In order to solve the above problems, the present invention provides a flat plate battery in which a power generation element is housed between a positive terminal plate and a negative terminal plate, which also serve as exteriors, and the peripheries of the positive and negative terminal plates are sealed with a sealing material. By providing protrusions on the outer peripheries of the positive terminal plate and the negative terminal plate, it was possible to provide a flat battery that can collect current even at these protrusions.

この突起部でもリードが取り出せる。In the present invention, since the power generation element is housed between the positive terminal plate and the negative terminal plate, which also serve as the exterior, it is advantageous in increasing the battery capacity when the battery thickness is constant. In addition, for electrical connections between batteries and devices containing batteries, in addition to being able to take out the leads from both the top and bottom of the battery,
The lead can also be taken out from this protrusion.

０のＩＣカードも十分実用化できる訳である。For example, an IC with a thickness of 0.76++m that complies with the Is○ standard
If the card has a built-in battery, the battery thickness should be Q, 47n+
If so, the resin thickness of the IC card alone would be 0.14 mm, and if you consider the battery thickness, the tolerance of the resin thickness, the margin in the thickness direction, etc., it would be very difficult to design a lead to take out the leads from the top and bottom of the battery. However, if the protrusion is provided in the horizontal direction of the battery as in the present invention, the thickness is 0.76
0 IC cards can also be put to practical use.

第１表
第１表より明らかなように、従来電池に比べて本発明電
池の容量は約２倍大きいことが分かる。As is clear from Table 1, the capacity of the battery of the present invention is approximately twice as large as that of the conventional battery.
この理由は次のようである。本発明電池が外装と集電体
を兼ねて封口端子板の厚みが３０μなので、電池厚み０
．４７ｍで発電要素の厚みが０．４１である。The reason for this is as follows. In the battery of the present invention, the thickness of the sealed terminal plate that serves as the exterior and the current collector is 30μ, so the battery thickness is 0.
．． It is 47 m long and the thickness of the power generation element is 0.41.
一方、従来電池は外装フィルムがポリエステル／Ａ１／
ポリエステルの三層ラミネートで厚みが各々４０，２０
．４０μで合計１００μである。On the other hand, the outer film of conventional batteries is polyester/A1/
Three-layer polyester laminate with thicknesses of 40 and 20 mm respectively
．． 40μ for a total of 100μ.
さらに、この外装フィルム内面に配された集電体厚みが
３０μである。Furthermore, the thickness of the current collector disposed on the inner surface of this exterior film was 30 μm.
従って、従来電池の外装厚みは１３０μとなり、電池厚
み０．４７ｍに対して発電要素は０．２１ｍｍと本発明
電池の約５０％と減ってしまうことになる。Therefore, the exterior thickness of the conventional battery is 130 μm, and the power generating element is 0.21 mm compared to the battery thickness of 0.47 m, which is about 50% of that of the battery of the present invention.
次に、本発明電池の貯蔵性を調べた。Next, the storability of the battery of the present invention was investigated.
試験方法は電池を６０℃、Ｒ８９０〜９５％の恒温恒湿
槽に貯蔵し、回路電圧（Ｖｏｃ）、内部抵抗（Ｒｉ）、
厚み（Ｈ）の変化を調べた。この結果を第２表に示す。The test method is to store the battery in a constant temperature and humidity chamber at 60°C and R890-95%, and measure the circuit voltage (Voc), internal resistance (Ri),
Changes in thickness (H) were investigated. The results are shown in Table 2.
データはｎ＝２４である。The data are n=24.
表中、Ｘはデータｎ−２４の平均値、Ｒはデータの最大
値と最小値の差を示す。また、Ｖｏｃ。In the table, X indicates the average value of data n-24, and R indicates the difference between the maximum value and minimum value of the data. Also, Voc.
Ｒｉ＋Ｈの単位は各々、■、Ω、ｆｌである。The units of Ri+H are ■, Ω, and fl, respectively.
第２表から明らかなように、本発明電池は回路電圧の維
持性が良好で、内部抵抗の上昇も少なく良好であること
が分かる。さらに、電池厚みの増加も極めて小さいこと
が分かる。As is clear from Table 2, it can be seen that the battery of the present invention has a good ability to maintain circuit voltage and has a small increase in internal resistance. Furthermore, it can be seen that the increase in battery thickness is also extremely small.
このように、本発明電池が優れていることの理由は従来
例２に示した従来電池に比べて、正極端子板に予め絞り
加工を施しているため、電池発電要素を内蔵しても電池
外周部のヒートシール時にこのシール部に無理な力が加
わらないためである。In this way, the reason why the battery of the present invention is superior is that compared to the conventional battery shown in Conventional Example 2, the positive terminal plate is drawn in advance, so even if the battery power generating element is built in, the battery outer periphery is This is to prevent excessive force from being applied to the sealed portion during heat sealing.
以上のように、正極端子板と負極端子板の外形寸法を０
．６〜１．０ｍｍ相違させれば、電池外周部をヒートシ
ールにより封口するときに発生するショートを防止する
ことができる。As mentioned above, the external dimensions of the positive terminal plate and negative terminal plate are set to 0.
．． If the difference is 6 to 1.0 mm, it is possible to prevent short circuits that occur when sealing the outer circumference of the battery by heat sealing.
また、リード端子の役割を果たす前記突起部の長さの半
分以上はヒートシール時にハミ出した封口材で被われる
ことなく、露出するようにさせることにより、ＩＣカー
ド電源接続部と電池が確実に電気的に接続されるように
なる。In addition, more than half of the length of the protrusion, which serves as a lead terminal, is exposed without being covered with the sealing material that comes out during heat sealing, so that the IC card power supply connection part and battery can be securely connected. become electrically connected.
さらに、負極端子板にニッケル、ステンレス、正極端子
板にアルミニウム、ステンレスを用いることにより、電
池の外装と集電体をこの正・負極端子板が兼ねるので電
池を謹めて薄く出来る。Furthermore, by using nickel or stainless steel for the negative terminal plate and aluminum or stainless steel for the positive terminal plate, the positive and negative terminal plates serve as the exterior of the battery and the current collector, so the battery can be made thinner.
また、正・負極端子板の一部が突起部なので、電池上下
方向から電池押えバネでリードを取ることができるし、
この突起部からもリードが取れる。Also, since some of the positive and negative terminal plates are protrusions, you can take the leads from the top and bottom of the battery using the battery holding spring.
Leads can also be taken from this protrusion.
さらに、この突起部は正・負極端子板と一体となってい
るので、改めて電池にリード端子を溶接したり、ハンダ
付したりする必要がない。Furthermore, since the projections are integrated with the positive and negative terminal plates, there is no need to weld or solder the lead terminals to the battery.
また、この実施例では、正・負極端子板の厚みを３０〜
３５μとすることにより、電池ケースを極限まで薄くし
て発電要素を出来る限り多くして電池容量を大きくする
と同時に、リード端子を兼ねる突起部の強度保証をして
いる。In addition, in this example, the thickness of the positive and negative terminal plates is 30~
By setting the thickness to 35μ, the battery case is made as thin as possible and the number of power generating elements is increased as much as possible to increase the battery capacity, while at the same time ensuring the strength of the protrusions that also serve as lead terminals.

ド端子として使用できる。As described in detail above, the present invention is a flat plate battery in which a power generating element is housed between a positive terminal plate and a negative terminal plate which also serve as an exterior, and the peripheries of the positive and negative terminal plates are sealed with a sealing plate. ,
By providing protrusions on the outer peripheries of the positive terminal plate and the negative terminal plate, the protrusions can be used as lead terminals for taking out electricity from the battery.
また、リチウムを負極活物質とする１次電池および２次
電池に適用すれば、１．５Ｖ系の電池や水溶液系の電池
に比べて電圧が高く、漏液の心配がないので５〜１０年
使用する電池として有効である。In addition, if applied to primary and secondary batteries that use lithium as the negative electrode active material, the voltage is higher than that of 1.5V batteries or aqueous batteries, and there is no need to worry about leakage, so it can last for 5 to 10 years. It is effective as a battery to use.
