造工程を第４図に示している。<<Prior Art>> One typical structure of a thin battery is one in which a frame-like frame is interposed in the peripheral seal portion of an exterior film. A conventional manufacturing process for a thin battery having this configuration is shown in FIG.
まず第４図Ａのように、プラスチツクを主体に
したラミネートフイルムからなる四角形の外装フ
イルム１０を用意し、その周縁部を除く上面側に
負極集電板１２を接着するとともに、このフイル
ム１０とほぼ同じ外径寸法の合成樹脂製の枠体１
４を外装フイルム１０の上面周縁部に接着する。 First, as shown in FIG. 4A, a rectangular exterior film 10 made of a laminate film mainly made of plastic is prepared, a negative electrode current collector plate 12 is adhered to the upper surface side excluding the peripheral edge, and the film 10 is approximately Synthetic resin frame 1 with the same outer diameter dimensions
4 is adhered to the upper peripheral edge of the exterior film 10.
次にＢのように、枠体１４の内部における負極

と同様なもう１枚の外装フイルム２４の下面側に
正極集電板２６を接着しておき、それを前記発電
要素および枠体１４の上面側に被せる。 Next, as shown in B, a thin-layer power generation element formed by laminating the gelled negative electrode 18, the separator 20, and the positive electrode mixture 22 in this order is loaded on the upper surface of the negative electrode current collector plate 12 inside the frame 14. Next, the exterior film 10
A positive electrode current collector plate 26 is adhered to the lower surface side of another exterior film 24 similar to the above, and the positive electrode current collector plate 26 is placed over the upper surface side of the power generating element and the frame body 14.

用の端子部となる。 Then, as shown in C, the peripheral edges of the two exterior films 10 and 24 are thermocompression bonded to the upper and lower surfaces of the frame 14 to seal the inside of the battery. Note that terminal window holes 16 and 28 are formed in the centers of the exterior films 10 and 24, and the negative electrode current collector plate 12 and the positive electrode current collector plate 26 are exposed in these portions, respectively, and these serve as terminal portions for external connection. becomes.
《発明が解決しようとする問題点》
上記の薄形電池において、２枚の外装フイルム
１０と２４で内部の発電要素を挾み込み、発電要
素の各層間の密着性を良好にするために、第４図
Ｃに示すように、電池組立後の枠体１４の厚さは
内部の発電要素の厚さよりある程度小さくしなけ
ればならない。<<Problems to be Solved by the Invention>> In the thin battery described above, in order to sandwich the internal power generation element between the two exterior films 10 and 24 and improve the adhesion between each layer of the power generation element, As shown in FIG. 4C, the thickness of the frame 14 after the battery is assembled must be somewhat smaller than the thickness of the power generation element inside.
そのため従来は第４図Ｂのように、発電要素の
厚さ（集電板も含む）Ｈよりも小さな厚さｈの枠
体１４を用いていた。 Therefore, conventionally, as shown in FIG. 4B, a frame 14 having a thickness h smaller than the thickness H of the power generation element (including the current collector plate) has been used.
ところが、枠体１４の初期の厚さｈが発電要素
の厚さＨより小さいことから、第４図Ｂに示す組
立工程や前述の熱圧着工程で次のような問題を生
じていた。 However, since the initial thickness h of the frame 14 is smaller than the thickness H of the power generation element, the following problems have occurred in the assembly process shown in FIG. 4B and the above-mentioned thermocompression bonding process.
枠体１４の内部空間に薄層状の発電要素を順次
装填する際に、正極合剤２２の粉末や電解液など
を枠体１４の上面に付着させてしまつたり、セパ
レータ２０の端部の繊維を枠体１４の上面と外装
フイルム２４の間に挾み込んだりしやすい。枠体
１４の上面を不純物で汚染したり、あるいは繊維
を噛み込んだりしたままで枠体１４と外装フイル
ム２４とが熱圧着で接合しても、その部分でシー
ル不良が発生しやすい。 When sequentially loading thin-layer power generation elements into the internal space of the frame 14, powder of the positive electrode mixture 22, electrolyte, etc. may adhere to the upper surface of the frame 14, or the fibers at the ends of the separator 20 may can be easily inserted between the upper surface of the frame 14 and the exterior film 24. Even if the frame 14 and the exterior film 24 are bonded by thermocompression bonding while the upper surface of the frame 14 is contaminated with impurities or fibers are caught, sealing failure is likely to occur in that part.
つまり、枠体１４の上面の高さが発電要素の厚
さより低くなるため、枠体１４の大切な上面シー
ル部を汚染したり、不要な繊維を噛み込んだりし
やすく、外装フイルム２４との接着不良が生じや
すい。そのような接着不良部分からは電解液など
が容易に漏出するため、耐漏液性能が著しく低下
する。 In other words, since the height of the upper surface of the frame body 14 is lower than the thickness of the power generation element, the important upper sealing part of the frame body 14 is easily contaminated, unnecessary fibers are easily caught, and the adhesion with the exterior film 24 is increased. Defects are likely to occur. Since electrolytic solution and the like easily leak from such a portion with poor adhesion, the leakage resistance performance is significantly reduced.
この発明は前述した従来の問題点に鑑みなされ
たものであり、その目的は、特に製造工程を煩雑
なものにすることなく、枠体の上面と外装フイル

漏液性能に優れた薄形電池を歩留り良く生産でき
るようにする点にある。 This invention was made in view of the above-mentioned conventional problems, and its purpose is to reduce seal failure between the upper surface of the frame and the exterior film without particularly complicating the manufacturing process. The object of the present invention is to enable the production of thin batteries with high yield and excellent leakage resistance.
《問題点を解決するための手段》
この発明に係る薄形電池の製造方法は、上記熱
圧着工程前の上記枠体の厚さが上記発電要素の厚
さより大きくしておき、熱圧着工程で枠体を圧縮
変形することで、最終的な枠体の厚さが発電要素
の厚さより小さくなるようにした。<Means for Solving the Problems> In the method for manufacturing a thin battery according to the present invention, the thickness of the frame body before the thermocompression bonding process is made larger than the thickness of the power generation element, and the thickness of the frame body before the thermocompression bonding process is By compressively deforming the frame, the final thickness of the frame was made smaller than the thickness of the power generation element.

In addition, the fibers at the ends of the separator are less likely to be caught in the upper surface of the frame.

出している。 First, as shown in Figure 1A, a polyester layer
12μm + aluminum foil 9μm + nylon layer 15μm +
An exterior film 10 made of a laminate film with a polyethylene layer of 50 μm is prepared, and a negative electrode current collector plate 12 made of copper foil is adhered to the inner surface of the battery (the polyethylene layer side) via an epoxy resin adhesive and a hot melt adhesive. The negative electrode current collector plate 12 is not bonded to the upper peripheral edge of the exterior film 10, and a frame 14, which is an integrally molded polyethylene product, is bonded to that portion. Thickness h of this frame 14
1 is sufficiently larger than that of a conventional thin battery of the same size, and is larger than the thickness of the power generating element described above. Note that a terminal window hole 16 is formed in the center of the exterior film 10, and the negative electrode current collector plate 12 is exposed at that portion.
次に第１図Ｂに示すように、枠体１４の内部の

層装填する訳である。 Next, as shown in FIG. 1B, a thin-layer power generation element consisting of the gelled negative electrode 18, the separator 20, and the positive electrode mixture 22 is sequentially loaded onto the negative electrode current collector plate 12 inside the frame 14. This embodiment is an alkaline battery, and the gel negative electrode 18 is a gel made of amalgamated zinc powder, sodium polyacrylate, and potassium hydroxide solution. Separator 20 is made of vinylon nonwoven fabric. The positive electrode mixture 22 is made of a mixture of manganese dioxide, graphite, etc., and is formed into a thin pellet shape. These are stacked and loaded into the frame 14 one after another.
ここで注目すべきことは、枠体１４の厚さｈ１

の上面側に載せてしまうことも極めて少くなる。 What should be noted here is the thickness h1 of the frame 14
is larger than the thickness H of the entire power generation element. Therefore, the powder of the positive electrode mixture 22, the electrolyte, etc. are less likely to adhere to the upper surface of the frame 14, and the end fibers of the separator 20 are less likely to be attached to the upper surface of the frame 14.
It is also extremely unlikely to be placed on the top side of the screen.

よび枠体１４の上面側に被せる。 In addition, a positive electrode current collector plate 26 (a nickel-plated iron foil ) are adhered using hot melt adhesive and epoxy resin adhesive. The positive electrode current collector plate 26 is not bonded around the lower surface of the exterior film 24 . Further, a terminal window hole 28 is formed in the center of the exterior film 24, and the positive electrode current collector plate 26 is exposed at that portion. This exterior film 24 is placed over the power generation element and the upper surface of the frame 14 .

ることができる。 Then, as shown in FIG. 1C, the upper and lower surfaces of the frame 14 are sandwiched between the peripheral edges of the exterior films 10 and 24, respectively, and these portions are further sandwiched with a heating jig and heated and pressurized. Now the exterior film is 10,
24 is thermocompression bonded to the frame 14, and the frame 1
4 is compressed and deformed. Frame 14 after this compression deformation
The thickness h2 of is made smaller than the thickness H of the power generation element. In this case, the amount of compression of the frame 14 is greater than in the past, but the frame 14 made of synthetic resin such as polyethylene can be easily compressed by applying pressure while heating.

的容易である。 In the embodiment shown in FIG. 1, the cross-sectional shape of the frame 14 is rectangular, but the present invention is not limited to this, and the frame 14 may have a shape as shown in FIG. 2 or 3. Good too. In the embodiment shown in FIG. 2, the upper surface of the frame 14 is an inclined surface 14a that is higher on the inside. In the embodiment shown in FIG. 3, a thin rising peripheral wall 14b is integrally formed on the upper surface of the inner surface of the frame 14. According to the embodiment shown in FIG. 2 or 3, it is relatively easy to deform the frame 14 having the maximum thickness h1 to the thickness h2 shown in FIG. 1 by heat compression.
