The present invention relates to a built-in battery characterized by a method for minimizing the thickness, length, and width, which are increased when a battery is manufactured from a battery.

In general, in the early stages of the release of mobile technology, a special layer was used to transmit and receive radios. Today, due to the advances in semiconductor design technology, technologies for miniaturization and multifunctionality, which are easy to carry and have many functions and excellent performance, are being developed.

This is especially true in the field of batteries, and many technologies have been advanced.In the early stages, the cover and the battery are integrated, so if the cover is damaged due to external shock or the battery reaches the end of its life, it is inevitable to replace it with a new pack. As a result, it was impossible to recycle resources. However, due to the advances in technology as of today, it is now common to separate batteries and packs, and much effort has been made in the battery parts, but it seems to be insufficient to develop satisfactory technology. Therefore, in order to solve this problem in the present technology, the following problems were selected.

Fastening and separation can be accomplished by ultrasonic welding of the parts that need to be protected from external influences and positioning of nickel plates, protection circuits, etc. to protect lithium-ion batteries and lead + -electrode. It aims to provide a built-in battery that is convenient and excellent in positioning, dimension safety, strength and robustness.

Minimization of thickness, length, and width that are increased when manufacturing a battery pack of a battery, and easily deformed by external impact among assemblies such as a secondary battery, a protection circuit, a ptc, and a connection terminal. It is for explaining the structure of the battery and the protection circuit assembly which is described with reference to the accompanying drawings as follows.

1 is an elevational view of a built-in battery, a basic unit that directly changes chemical energy to provide an electrical energy source, a rechargeable secondary battery in which electrical capacity is induced from oxidation and reduction of lithium, and a lithium ion battery (Li-Ion). When an overcurrent flows into the circuit at one side fastening portion 2 of the electronics 1, the polyswitch changes from a low resistance to a high resistance by the heat generated by this current, thereby limiting the overcurrent to limit the internal current of the device. A fuse that protects the circuit. When the overcurrent factor is eliminated and the temperature of the device decreases, the resistance value returns to the initial low value, so that the normal operation of the circuit is possible. Battery charge on the B " + " pole Ni-plate 4 connected to the positive electrode of the ion battery 1, and the B "-" pole Ni-plate plate 5 connected to the negative electrode of the lithium ion battery 1 In case of abnormal discharge / discharge To protect the battery from the risk of explosion, and to maintain a long life and high performance of the battery (positive temperature coefficient) (6) fastening the lithium ion battery (1) on top of the flexible both sides to induce induced electromotive force After designing the antenna with fpcb (flexible circuit board) and combining the insulator which minimizes the electric effect of the cell phone battery, it is embedded in the cell phone battery and the loop antenna 7 for RF communication of 13.56MHz is fastened. It is the part that is combined with the top case lower to cover the 1/2 section of the protection circuit (6) of the one, and the other side of the upper case upper (8) with the welding end installed to enable the ultrasonic welding. Top case lower equipped with ultrasonic welding end for positioning of protection circuit and terminal, securing safety and strength by ultrasonic welding Wer (9) is engaged and engaged, and double-sided tape is attached to the inside of the case to prevent the battery from coming off and to fix the bottom case (10) that protects the battery and the roof antenna The main purpose of the battery is to prevent the short circuit of the battery on the back of the loop antenna, and to fasten the insulating tape 11 which protects the battery from external shock, and the model mark of the product is placed thereon. And a label 12 attached to display characteristics, methods of use, precautions, and the like.

FIG. 2 is a fastening elevation view of a vertical internal battery, in which an outer upper portion of the protection circuit 6 is fastened to a top case lower 9 and a top case upper 8, and a lower portion thereof is a bottom case 10. By fastening the outer structure to the label 12 is shown.

3 is a side cross-sectional view of a vertical internal battery, in which a ptc plate 3 and a B " + " pole Ni-plate plate (1) are connected to one side fastening portion 2 of a Li-ion battery 1; 4), the protection circuit 6 of which the protection circuit 6 is fastened on the B "-" pole Ni-plate plate 5 and the loop antenna 7 is fastened on the lithium ion battery 1. When the top case upper (8) is fastened to the opposite side of the fastened upper case upper (8) to cover the half of the part, the upper case lower (9) is engaged with the ultrasonic welding mount (13). The bottom case 10 is fixed to the bottom of the lithium ion battery, and an insulating tape 11 is fastened to the back of the loop antenna, and a label 12 is placed thereon. The complete structure is shown.
