This invention relates to a battery having a structure in which a terminal surface of a unit cell inside an outer case and an external terminal provided on the outer case are electrically connected. As mentioned above, many batteries, represented by single-type alkaline batteries, have a terminal surface (the outer surface of the metal can that also serves as the terminal) of the unit cell housed in the outer case, and
The structure is such that an external terminal provided in the outer case (forming a part of the outer case) is electrically connected inside the outer case. In this type of battery, the metal can of the cell is generally made of iron, nickel or tin-plated iron, or stainless steel, and the external terminal is made of nickel or tin-plated iron, or stainless steel. It is structured as follows. The metal can of the unit cell and the external terminal can be connected to each other by simply mechanically contacting them, or by spot welding them together. In the above-mentioned conventional batteries, where the cell metal can and the external terminal are connected only by mechanical contact, it is extremely difficult to maintain a stable contact pressure over a long period of time, and both As an insulating passive film is gradually formed on the contact surface, the contact resistance between the two may be small at first, but it cannot be kept stable over a long period of time, and if stored for a long period of time, the contact resistance may increase rapidly or the product may deteriorate. There were drawbacks such as large variations between the methods. Furthermore, in the case where the unit cell metal can and the external terminal are spot welded, the electrical connection between the two is good and stable, except for some welding failures. However, the first drawback is that it requires expensive machinery and equipment for spot welding, and the production process becomes complicated. Another serious drawback is that if the process of spot welding is not adequately controlled, many defective products due to the above-mentioned welding failures will occur. Furthermore, in order to perform spot welding well, there are restrictions on the materials (material and type of plating) for the cell metal can and external terminals.
Another drawback is that there is less freedom in selecting and combining materials. Therefore, conventional batteries have a structure in which a spring is interposed between the terminal surface of the unit cell and the external terminal, and grease containing a conductive material is further interposed on the contact surface between the spring and the terminal surface of the unit cell. had been proposed. In this battery, the terminal side of the unit cell and the external terminal side are electrically connected using a spring and grease containing a conductive material, instead of using spot welding, which has various problems as described above. This allows for relatively good electrical contact between the cell terminal surface and the external terminals, without being subject to restrictions on the materials of the cell side and the external terminal side, and even with relatively simple mechanical equipment. (Refer to Japanese Patent Application Laid-Open No. 149766/1983). However, this also requires a spring to be interposed between the unit cell terminal surface and the external terminal, and this spring is a relatively large proportion of the components of this type of battery in terms of cost. It occupies the Therefore, the problem arises that the cost increases accordingly, and furthermore, the process of interposing the spring member between the terminal surface of the unit cell and the external terminal also becomes troublesome. Additionally, grease containing a conductive material may indeed be able to provide good electrical contact when it is initially interposed between the spring and the cell terminal surface; however, For example, under relatively high-temperature storage conditions, the grease tends to flow out with the conductive material and lose its initial effectiveness, and in some cases, the conductive material that has flowed out with the grease may adhere to other locations. In the worst case, the leaked grease and conductive material may cause an internal short circuit or self-discharge. In other words, this battery was also unable to maintain good and stable electrical contact between the unit cell terminal surface and the external terminal over a long period of time. This idea was devised in view of the above-mentioned conventional problems, and its purpose was to be able to manufacture it through a simple assembly process that does not require expensive mechanical equipment, without any restrictions on materials, and without increasing the number of parts. To provide a battery capable of stably maintaining electrical contact between a unit cell terminal surface and an external terminal in a good state over a long period of time without increasing cost or complicating the process. In order to achieve the above object, this invention provides a battery having a unit cell A, an exterior case B, an anode external terminal 8, a cathode external terminal 12, and a conductive adhesive 9, the unit cell A is the terminal surface 1a, 5
a, 13a, the exterior case B houses the unit cell A therein, and has the anode external terminal 8 and the cathode external terminal 12, and the conductive adhesive 9 is , the terminal surface 1 of the unit cell A
A, 5a, 13a and the external terminals 8, 12. FIG. 1 shows a cylindrical alkaline battery according to a first embodiment of this invention. First, a cylindrical anode can 1, which also serves as a case for a unit cell A, contains inside it an anode active material 2 mainly composed of manganese dioxide, a separator 3 made of vinylon fiber, for example, containing an alkaline electrolyte, and a separator 3 made of, for example, vinylon fiber, containing gel-like zinc. The lower end of the anode can 1 is closed with a cathode sealing plate 11 connected to a cathode current collector 5, thereby forming a unit cell A. The outer periphery of the anode can of unit cell A is covered with an insulating heat-shrinkable tube 6, as shown in the enlarged view a. This unit cell A is housed within an exterior cylindrical body 7 that is the main body of an exterior case B. A cathode external terminal plate 1 is provided at the lower end of this exterior cylindrical body 7.
1 and an anode external terminal plate 8 are provided at the upper end, respectively, and an exterior case B is constituted by these. As shown in the enlarged view b, the anode external terminal plate 8 is mechanically connected to the terminal surface 1a of the anode can 1 of the unit cell A by a conductive adhesive 9, and also has a ring-shaped washer 10. Through this, the outer phase part is fixed by tightening the collecting part by the curl shaping tip part of the exterior cylindrical body 7. The above-mentioned conductive adhesive is made by dispersing conductive substances such as silver, carbon black, graphite, etc. in fine particles in an epoxy adhesive, and connects the anode can 1 to the anode through the conductive adhesive 9. An external terminal board 8 is electrically connected. Note that a conductive adhesive 9 having the same structure as described above is also interposed between the terminal surface 5a of the cathode current collector 5 and the cathode external terminal plate 11. Since the battery of this invention is constructed as described above, even if the clamping force of the anode external terminal 8 by the curled tip between the outer cylinders 7 is uneven or weakens over time, the anode External terminal 8 and anode can 1
are bonded with conductive adhesive 9 and are electrically connected at the same time, so the electrical contact resistance is kept small and stable over a long period of time without being affected by the reduction in the tightening force mentioned above. can be kept. In addition, since the joint surface between the anode external terminal 8 and the anode can 1 is coated with the conductive adhesive 9, an insulating passive film is not formed on this part, and therefore there is no contact between the two. The resistance can be kept low and stable for a long period of time. In addition, expensive mechanical equipment such as spot welding is not required, and the bonding process using the conductive adhesive 9 is simpler than spot welding and is easier to manage.
It has good mass productivity, and there are fewer defects such as welding defects. Furthermore, there are no restrictions on materials as in the case of spot welding. The conductive adhesive 9 is fixed between the anode external terminal 8 and the anode can 1 without fear of flowing out like grease, and provides a stable mechanical and electrical connection between the two over a long period of time. I can continue. Further, there is no need to interpose a component such as a spring between the anode external terminal 8 and the anode can 1, and the two can be directly mechanically and electrically connected. Therefore, the number of parts is small, the construction can be made at low cost, and there is almost no increase in the complexity of the process. Furthermore, since the conductive adhesive 9 is stably fixed to the part where it is used over a long period of time,
There is no fear that it may leak out and cause an internal short circuit or self-discharge. The same applies to the conductive adhesive 9 used on the cathode side. FIG. 2 shows another embodiment of this invention. The battery in this embodiment is an alkaline battery having a structure in which four unit cells A are housed in a stacked manner in an exterior case B, and these unit cells A are connected in series and connected to an anode external terminal 8 and a cathode external terminal 12. It is a button type battery. Here, the anode external terminal 8
and the terminal surface 1a of the anode can 1, the cathode external terminal 1
2 and the terminal surface 13a of the cathode terminal 13, the anode can 1 and the anode terminal 13 of each unit cell A are mechanically and electrically connected by a conductive adhesive 9, respectively. Next, we will compare the battery according to this invention constructed as described above with a battery of the same type made by conventional mechanical contact and spot welding, and examine the changes over time in the contact resistance between each anode external terminal 8 and anode can 1. The test results are shown in Table 1. The storage conditions for this test are temperature 45
℃ and 90% humidity, and the test results for each battery are
Shown as an average of 100 items.

Furthermore, it does not require much troublesome process control and is highly suitable for production.
