本発明は、複数個の扁平型電池を並列接続した集合電池
に関する。DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a battery assembly in which a plurality of flat batteries are connected in parallel.
近年、電子機器の小形化、薄型化に伴い、それらの電源
となる電池にも薄型化の要求が高まっている。しかしな
がら、従来のボタン型、コイン型の電池では、その厚さ
は最低でも１．０麿程度までしか薄型化できず、前記要
求を充分満足させるものではなかった。In recent years, as electronic devices have become smaller and thinner, there has been an increasing demand for thinner batteries that power these devices. However, in conventional button-type and coin-type batteries, the thickness can only be reduced to at least about 1.0 mm, and the above requirements cannot be fully satisfied.
このようなことから、正極及び負極の端子板間に例えば
ポリエチレン等からなる枠状の絶縁封口′板を介在させ
、これら端子板と枠状絶縁封口板とにより形成された空
間内に発電要素を収納し、前記正負極の両端子板と絶縁
封口板とを加熱融着して前記電池要素を密封口した構造
の扁平型電池が提案されている。なお、前記発電要素は
金属ハロゲン化物又は酸化物からなる正極合剤シートと
リチウム等の軽金属からなる負極シートと、これら合剤
シート及び負極シートの間に介在され、非水電解液を含
浸したセパレータとからなるものである。こうした構造
の扁平型電池では、その厚さを１．０ｊＩｌより薄くで
き、その要求を満足することができる。For this reason, a frame-shaped insulating sealing plate made of polyethylene or the like is interposed between the positive electrode and negative electrode terminal plates, and the power generation element is placed in the space formed by these terminal plates and the frame-shaped insulating sealing plate. A flat type battery has been proposed in which the battery element is housed and sealed by heat-sealing both the positive and negative terminal plates and an insulating sealing plate. The power generation element includes a positive electrode mixture sheet made of a metal halide or oxide, a negative electrode sheet made of a light metal such as lithium, and a separator interposed between these mixture sheets and the negative electrode sheet and impregnated with a non-aqueous electrolyte. It consists of. In a flat battery having such a structure, the thickness can be made thinner than 1.0jIl, and this requirement can be satisfied.
ところで、電子機器によっては、より大きな容量を必要

及び負極端子板同志に電気溶接して接続した構造のもの
が知られている。By the way, some electronic devices require a larger capacity, and in such cases, an assembled battery is used in which a plurality of the above-mentioned flat batteries are connected in parallel depending on the required discharge state. Conventionally, such an assembled battery is known to have a structure in which metal lead terminals are electrically welded to the positive terminal plates and negative terminal plates of adjacent flat batteries.
しかしながら、集合する厚さ１．０ａｗ＊の扁平型電池

あった。また、集合電池全体の厚さを薄くするために、

いて接続不良を生じる。更に、電気溶接を採用するため
に集合扁平電池の組立てが繁雑となる。However, since the terminal plate of the assembled flat type battery having a thickness of 1.0 aw* is thin, there is a risk that a hole may be made in the terminal plate due to the heat generated during electric welding of the lead terminal. In addition, in order to reduce the overall thickness of the assembled battery,
The lead terminals used also need to be thin, but if a thin lead terminal is used, a hole will be created in the lead terminal during electric welding, resulting in poor connection. Furthermore, the use of electric welding makes assembly of the flat battery assembly complicated.

ものである。[Summary of the Invention] The present invention provides a method in which a frame-shaped insulating sealing plate is interposed between both terminal plates of sheet-shaped positive and negative electrodes, and a battery power generating element is housed in a space surrounded by both terminal plates and the sealing plate. The battery is characterized in that flat batteries with sealed openings are connected in parallel by bonding the positive terminal plates and the negative terminal plates together using an adhesive conductive film.

As shown in FIG. 2, these batteries 1L to 1L are formed by interposing a rod-shaped insulating sealing plate 4 between the terminal plates 2.3 of the positive and negative electrodes, and these terminal plates 2.3 and the frame-shaped insulating sealing plate 4. The J power generating element 5 is housed in the space, and the battery element 5 is sealed by heat-sealing the positive and negative terminal plates 2.3 and the insulating sealing plate 4.

れる。The upper L to upper portions of each of the flat batteries are arranged adjacent to each other in a plane so that the positive terminal plate 2 and the negative terminal plate 3 are located on the same side, respectively. Then, on each battery L-
Adhesive conductive films 9 are adhered to the upper and lower surfaces of ~jJ- and are connected in parallel to each other. That is, the conductive film 9 is bonded so that the positive terminal plates 2 and the negative terminal plates 3 of each battery 1L-13 are connected to each other. The conductive film 9 is made by dispersing carbon powder, silver powder, or copper powder in a heat-fusible resin such as an ethylene-vinyl acetate copolymer or an ionic copolymer obtained by ionically crosslinking an ethylene-acrylic acid copolymer. A copper foil coated with conductive adhesive on both sides is used. When the former conductive film is used, it is adhered to each battery by heat fusion, and when the latter conductive film is used, it is adhered as is.

ことができる。According to the present invention, since the upper L to upper ends of each flat battery are connected in parallel with each other using the adhesive conductive film 9, holes are not made in the thin positive and negative terminal plates 2.3. A battery assembly that is easily and firmly connected can be obtained.

When thermal bonding was performed at 120° C. using an adhesive conductive film (based on a heat-fusible resin), an assembled battery with good connection strength could be obtained. On the other hand, using nickel foil with a thickness of 0.05 mm instead of the conductive film, three similar flat batteries with a thickness of 0.5 m were electrically welded to reduce the thickness of the positive and negative terminal plates and the nickel foil. Because it was extremely thin, the heat generated during electric welding caused it to melt, resulting in poor connection between the batteries. Such defects were found in 27 sets of assembled batteries out of 100 sets.
