Abstract

PROBLEM TO BE SOLVED: To make such processing unnecessary as special spacing or folding even when a plurality of batteries are mounted on a single equipment. SOLUTION: Electrodes 2a, 3a, 2b, 3b are disposed by biasing from the center P of an edge side of flat rectangle main bodies 1a, 1b. When two batteries are mounted on a single equipment, one battery is disposed by turning it over so that an edge side with electrodes 2a, 3a and another edge side with electrodes 2b, 3b face each other. The electrodes 2a, 3a and 2b, 3b can be disposed by butting mutually close in such a manner as almost in contact with the counterpart's main body.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery used for a small electronic device.

[0002]

2. Description of the Related Art There are various types of batteries used as power supplies for small electronic devices. One of them is the lithium polymer battery shown in FIG. 1, which is commercially available. As shown in FIG. 1, this battery has a flat rectangular main body 1, and a battery 1 extending outward from one end of the rectangular main body 1.
It comprises a pair of electrodes 2 and 3. The electrodes 2, 3 are
Of course, one is a positive electrode and the other is a negative electrode, but each has a thin foil shape.

[0003]

The above-mentioned conventional flat type lithium polymer battery is disposed symmetrically with respect to the center of the edge where the pair of electrodes are disposed.
Therefore, when a plurality of batteries are mounted on a device and used in series or parallel connection, as shown in FIG. 2, the electrodes 2a and 3a of one battery and the electrodes 2b and 3b of the other battery are used.
Even if the batteries are placed face-to-face with each other,
Even if one side is the back side, it will face up, and depending on the case, in order to avoid the contact of the electrodes, the electrodes of both batteries are spaced apart so that they do not come close or the electrodes are bent or the like. For this reason, a space is required when batteries are spaced. In addition, there is a problem that the bending is time-consuming and may cause damage to the electrode due to the bending.

[0004] The present invention has been made in view of the above problems, and provides a battery that does not require a special space or a bending process even when a plurality of batteries are mounted on one device. It is an object.

[0005]

According to the battery of the present invention, the main body is flat and rectangular, and one of the four sides of the rectangular portion is provided.
In a configuration in which a pair of thin foil-shaped electrodes are provided on the end sides, the pair of electrodes are arranged so as to be offset with respect to the center position of one end side to be arranged.

In the battery according to the present invention, the pair of electrodes are arranged so as to be offset with respect to the center of one end, so that if one of them is turned upside down, the electrodes of one and the other will not face each other.
Since they are arranged at shifted positions and the electrodes of one battery can be arranged close to contact with the main body of the other battery, the interval between both batteries is reduced, that is, without taking up much space, Multiple batteries can be installed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail with reference to embodiments. FIG. 3 is an external perspective view of a lithium polymer battery according to one embodiment of the present invention. This embodiment of the lithium polymer battery includes a main body 1
Is flat and rectangular, and the electrodes 2 and 3 extend outward from one end side, which is the same as the conventional one shown in FIG.

However, the lithium polymer battery according to this embodiment is characterized in that the electrodes 2 and 3 are arranged at a position deviated from the center position P of one end of the main body 1 of the battery, that is, at one end of one end. This is different from the conventional one shown in FIG. In the lithium polymer battery of this embodiment, since the electrodes 2 and 3 are arranged so as to be deviated from the center position P, for example, when two batteries are mounted on a device, one of the batteries is turned upside down. When the batteries are arranged such that the electrodes face each other, as shown in FIG. 4, the electrodes 2a and 3a of one battery and the electrodes 2b and 3b of the other battery are located at the edges where the other electrode is not arranged. Therefore, the batteries can be arranged close to each other so as to be in contact with each other, and no space is required for providing an interval, and there is no need to bend the electrodes.

FIG. 5 is an external perspective view of a lithium polymer battery according to another embodiment of the present invention. This embodiment of the lithium polymer battery also differs from the conventional battery shown in FIG. 1 in that the main body 1 is flat and rectangular, and the electrodes 2 and 3 extend outward from one end. The same is true.

However, the lithium polymer battery according to this embodiment is arranged such that the center position P of one end of the battery body 1 is
It is different from the conventional battery shown in FIG. 1 in that the electrodes 2 and 3 are arranged in a biased manner. 3 differs from that shown in FIG. 3 in that one electrode 2 and the other electrode 3 are arranged on the left and right sides of the center position P. The distance from the center position P to the electrode 2 is set to be different from the distance from the center position P to the electrode 3.

As described above, in the lithium polymer battery of this embodiment, the electrodes 2 and 3 are arranged on the left and right with respect to the center position P at one end, and the distance from the center position P to the electrode is set to a different value. For example, when two batteries are mounted on a device, if one of the batteries is turned upside down and the batteries are arranged so that the electrodes face each other, FIG.
As shown in (1), the other batteries 2b, 3b are opposed to the electrodes 2a, 3a of one of the batteries in a manner shifted from each other, that is, to the edges where the other battery is not arranged, and the batteries come into contact with each other. The batteries can be arranged close to each other, and no space is required for providing a space between the batteries, and the batteries do not need to be bent.

In the lithium polymer battery of each of the above embodiments, even if the dimensions such as length and width differ depending on the application, the distance L between the electrode 2 and the electrode 3 shown in FIG.
By keeping the constant, it is possible to connect batteries of different dimensions to a charge / discharge device or a test / measurement device using the same connector.

Although the above embodiment has described a lithium polymer battery, the present invention is not limited to this.
The present invention can also be applied to other types of batteries in which the main body has a flat rectangular shape and a pair of electrodes extend outward from one end.

[0014]

According to the present invention, since a pair of electrodes are arranged so as to be deviated from the center of one end where the pair of electrodes are arranged, even when a plurality of batteries are mounted on one device, It is not necessary to provide a space for avoiding contact of the electrodes, and it is not necessary to perform a process such as bending of the electrodes. Therefore, it is possible to save labor and reduce the risk of breakage.
