Accordingly, even if at least a part of the flexible battery 140 is embedded in the band unit 112 side made of a flexible material or embedded in the wearing unit 110 in a bent state with a predetermined curvature, performance of the battery may be prevented from deteriorating. Can be. In addition, since the flexible battery 140 is implemented as a thin battery, the flexible battery 140 can be implemented with a high capacity while being relatively light in weight as compared with a conventional battery such as a square battery or a coin battery.

Such a flexible battery 140 may be built in the wearing unit 110, and may be electrically connected to a circuit board 132 embedded in the body 111.

In this case, the flexible battery 140 may be formed only on the side of the band part 112, but may be disposed to be simultaneously embedded in the body part 111 and the band part 112.

That is, as shown in FIGS. 4 and 5, the flexible battery 140 may be disposed such that the length of a part including both ends of the entire length is located inside the band part 112. It may be disposed to be located inside the body portion 111.

As described above, the flexible battery 140 applied to the present invention increases the overall length as compared with the band part 112 and the body part 111, which is embedded only in the band part 112 or only the body part 111. It is possible to increase the storage capacity further.

In addition, the flexible battery 140 may be protected by the body part 111 except for a part embedded in the band part 112 by only a part of the entire length is built in the band part 112 side. The portion embedded in the body portion 111 in the use process can prevent the bending occurs. In other words, even if the band portion 112 is made of a soft material, even if repeated bending occurs in the use process, the flexible battery 140 minimizes the occurrence of repeated bending among the entire lengths, thereby remarkably reducing the possibility of performance degradation or damage as a battery. Can be reduced.

In addition, since only a part of the entire length of the flexible battery 140 is accommodated in the receiving groove 114 side of the band part 112, the receiving groove 114 is also formed only in a part of the entire length of the band part 112. Can be. Accordingly, when both ends of the band part 112 are fastened to each other by means of restraining means corresponding to each other so that the band part 112 is formed of two members and maintained on the user's body, the both ends of the band part 112 are restrained. Constraints for can be implemented in a variety of ways.

Such a flexible battery 140 may include exterior materials 147 and 148 and an electrode assembly 141 as shown in FIG. 10, and the electrode assembly 141 is encapsulated inside the exterior materials 147 and 148 together with an electrolyte solution. It may be in the form.

In this case, the flexible battery 140 applied to the present invention may be provided with patterns 146 and 149 for contraction and relaxation in the longitudinal direction on the electrode assembly 141 and the exterior members 147 and 148, respectively.

Preferably, the first pattern 149 formed on the exterior members 147 and 148 and the second pattern 146 formed on the electrode assembly 141 may be provided to have the same directivity.

Such patterns 146 and 149 shrink the substrate itself by offsetting the amount of change in length caused by curvature even when the flexible battery 140 is built into the wearing unit 110 and the banding 112 occurs during use. Can be prevented or minimized.

In particular, the patterns 146 and 149 include a part embedded in the band part 112 of the entire length when the flexible battery 140 applied to the present invention is disposed to be embedded in both the body part 111 and the band part 112. It may be formed so as to include, the boundary area of the band portion 112 and the body portion 111 may also be formed.

That is, when the band portion 112 is made of a soft material, when the band portion 112 is repeatedly bent in use, the flexible battery 140 disposed in the accommodating groove 114 may also be repeatedly banded. . In addition, the flexible battery 140 disposed at the boundary area between the band part 112 and the body part 111 may be bent at a predetermined curvature.

In the present invention, the pattern 146 and 149 are formed in a portion where repetitive bending occurs and a portion arranged in a predetermined curvature to cope with the repeated bending and curvature, thereby preventing the occurrence of performance degradation or damage as a battery. To prevent it.

That is, the flexible battery 140 applied to the present invention prevents or minimizes the deformation amount of the substrate constituting the electrode assembly 141 and the exterior members 147 and 148 through the patterns 146 and 149 so that bending occurs even when bending occurs. By minimizing the amount of deformation of the substrate itself, which may occur, the electrode assembly 141 and the exterior members 147 and 148 may be prevented from being damaged or the performance of the battery may be degraded.

However, the formation positions of the patterns 146 and 149 are not limited thereto, and may be formed with respect to the entire length of the flexible battery 140 or may be partially formed with respect to some length. In this case, the patterns 146 and 149 may be continuously formed in a direction parallel to the width direction of the electrode assembly 141 and the exterior members 147 and 148, or may be formed discontinuously.

In this case, the first pattern 149 and the second pattern 146 applied to the present invention may be formed such that the first pattern 149 and the second pattern 146 coincide with each other as well as the same direction. This is to allow the same behavior to always occur between the first pattern 149 and the second pattern 146.

As described above, the flexible battery 140 applied to the present invention is formed on the electrode assembly 141 and the exterior members 147 and 148 so that the patterns 146 and 149 for the contraction and relaxation in the longitudinal direction generated during bending match each other. Even if bending in the longitudinal direction occurs, the electrode assembly 141 and the exterior members 147 and 148 may always maintain a uniform interval or contact state with respect to the entire length. For this reason, since the electrolyte solution encapsulated with the electrode assembly 141 is uniformly distributed over the entire length, it is possible to prevent the performance of the battery from being lowered.

For example, each of the peaks and valleys of the first pattern 149 and the second pattern 146 may be formed in a direction parallel to the width direction of the exterior members 147 and 148 and the electrode assembly 141. The ridges and valleys may be alternately disposed along the lengths of the 147 and 148 and the electrode assembly 141. In addition, the peaks and valleys constituting the first pattern 149 and the second pattern 146 are formed at the same position as the peaks and valleys between the peaks and the valleys, so that the first pattern 149 and the second pattern ( 146 may coincide with each other.

Specifically, the peaks and valleys of the first pattern 149 and the second pattern 146 may be formed in a direction parallel to a straight line parallel to the width direction of the exterior members 147 and 148 and the electrode assembly 141. The peaks and valleys may be repeatedly arranged along the longitudinal direction (see FIG. 9).

The peaks and valleys may be provided to have the same pitch and width, but may be provided to have different pitches and widths.

As a result, even when the exterior members 147 and 148 and the electrode assembly 141 are embedded in a bent state, fatigue applied to the substrate itself through the patterns 146 and 149 may be reduced.

Meanwhile, as illustrated in FIG. 9, the first pattern 149 and the second pattern 146 may be formed at equal intervals or may be provided at different intervals between valleys adjacent to each other. In addition, the same interval and different intervals may be provided in combination.

It may also be in the form of a portion of the phase exposed.

In this case, the positive electrode active material 142b and the negative electrode active material 144b may contain a PTFE (Polytetrafluoroethylene) component. This is to prevent the positive electrode active materials 142b and 144b and the negative electrode active material 144b from being peeled or cracks from the current collectors 142a and 144a during bending.

Meanwhile, the separator 143 disposed between the anode 142 and the cathode 144 may have a nanofiber web layer 143b interposed on one surface or both surfaces of the nonwoven fabric layer 143a.

Here, the nanofiber web layer 143b may be a nanofiber containing at least one selected from polyacrylonitrile nanofibers and polyvinylidene fluoride nanofibers.

Preferably, the nanofiber web layer 143b may be composed of only polyacrylonitrile nanofibers to ensure radioactive and uniform pores.

The exterior members 147 and 148 may be formed of a plate-shaped member having a predetermined area, and the electrode assembly 141 and the electrolyte may be accommodated therein to protect the electrode assembly 141 from external force.
