Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composite battery having two or more types of battery voltages in one battery body.

In recent years, electronic devices with built-in batteries have become significantly lighter, thinner, and smaller, and there is naturally an increasing demand for batteries to be thin and capable of supplying a small power source. Particularly in small portable radios and pocket televisions, the large volume of the power supply section is one of the factors that determines the overall size and shape of the device.

In addition, portable cabin radios require only one power source battery,
Since the operating voltage is 1l-t, and the voltage is boosted not by one type but by a booster circuit or the like, the volume occupied by the device is also an obstacle to miniaturization and thinning. In addition, small and thin multi-voltage power supplies of the dot matrix type for component displays are expected to have great potential in promoting the miniaturization of liquid crystal displays in the future.

In order to meet these demands, the present invention provides a small and thin power source battery having multiple voltages in one battery body. Below is an example of a real gun? 8 will be explained in detail.

(Example 1) FIG. 1 is a sectional view of a composite battery of the present invention having two types of voltages, 6V and 6V. In the figure, 1 and 26 are negative electrode terminals that also serve as exterior materials, and are made of aluminum with a thickness of 20 μm.
This 50 μm long conductive plastic film (
(hereinafter referred to as conductive plastic) and laminated (hereinafter referred to as laminate).

The aluminum foils 1 and 23 need only have a minimum thickness to eliminate pinholes.

Further, the thickness of the aluminum foil mentioned above is set in order to make the overall thickness of the multiple batteries as thin as possible. Said 2 and 6, 10, 14.1B, 24° 28 conductor pullers are:
The base film 1, which is made of NBR and 4-bar vinyl as a pressure body, is mixed with carbon, which is a conductive material, and one without any pinholes is commercially available (Yuru.ro, 7, 11.15,
25.29 is mainly composed of sulfur particles, 30% by weight of zinc chloride, 5% by weight of ammonium chloride, and 2M of mercuric chloride. The negative electrode active material is thinly coated on the glass using a coating method such as screen printing.

It is preferable that 0.5% hydroxyethyl cellulose is added to the above 3 solutions to improve the printing drop quality. Yo V

The f-electrode active material layer is obtained by mixing 46% by weight of the electrolyte into the erized material and applying it to the conductive plastic and laminate by a screen printing method, an extrusion method, or the like.

It also serves as the positive terminal and exterior of the 2' Soike. In order to immobilize (A) and (B), the thickness of the aluminum was set to 50 μm, but the thickness is not particularly limited and may be 20 μm without pinholes.20°21.

Furthermore, the densities of the positive and negative electrode mixture layers were approximately 2.2 and 6.1, respectively. Table 1 shows the results of evaluating the batteries thus produced.

Although typical embodiments of composite batteries have been described above, the basic content of the present invention is that a single battery can be used without providing multiple battery storage spaces in electronic equipment that requires a multi-voltage power source. Just by setting up a storage space, you can create two or more types of '＋
The object of the present invention is to provide a battery for a multi-voltage power supply capable of supplying Ti voltage. Therefore, the examples shown in the above embodiments are merely representative of the true battery of the present invention.

By combining various battery shapes, sizes, and the types of voltage generated. A type of composite battery is considered.
