Here, when the antenna 150 for wireless power transmission is formed in a pattern on the circuit board, the circuit board may be formed integrally with the circuit board constituting the circuit unit 130 or may be a separate member .

The antenna 150 for wireless power transmission functions as an antenna for wireless power transmission for transmitting wireless power to the wireless power receiving antenna 18 provided in the portable electronic device 10, 130).

Here, the driving power of the circuit unit 130 for driving the antenna 150 may be a part of the power stored in the battery 120.

Here, the principle of power transmission / reception using the antenna 150 for wireless power transmission can be applied to both a known magnetic induction method and a self-resonance method for generating an electromagnetic field using a coil and transmitting electric power through the coil. Since the wireless charging technique using the magnetic induction method and the self-resonance method is a well-known technology, a detailed description thereof will be omitted.

At this time, a device accommodating portion 116 for preventing the flow of the portable electronic device 10 accommodated in the accommodating portion S may be provided inside the bag body 110 (see FIG. 6). The device housing part 116 may be formed at a position corresponding to the antenna 150 for wireless power transmission built in the bag body 110 and may be sized to accommodate the portable electronic device.

For example, the device housing part 116 may be provided to have a size approximately equal to at least one of a length and a width of a portable electronic device, for example, a portable terminal.

When the portable electronic device to be charged is inserted into the device housing portion 116, the wireless power receiving antenna 18 built in the portable electronic device 10 can receive the wireless power And is disposed at a position corresponding to the antenna 150 for transmission. In addition, since the portable electronic device 10 is prevented from flowing by the device housing portion 116, the wireless power transmission antenna 150 and the wireless power reception antenna 18 built in the portable electronic device are in an alignment state So that wireless charging can be smoothly performed.

Here, as an example of the fixing means for fixing the position of the portable electronic device 10 accommodated in the accommodating portion S, the pocket-type device accommodating portion 116 is exemplified. However, the present invention is not limited to this, A clip, and a Velcro-type portable electronic device can be fixed in the accommodation portion S or prevented from flowing, various known methods can be applied.

The battery 120 is installed in the bag body 110 and supplies power for charging the main battery of the portable electronic device 10.

The battery 120 may be a known battery having rigidity. However, even if the bag body 110 made of a soft material is deformed due to an external force during its use, Or a flexible battery having flexibility so that the problem of performance deterioration does not occur (see Fig. 11).

11 to 13, the flexible battery includes an electrode assembly 121 and exterior materials 127 and 128. The electrode assembly 121 is encapsulated in the exterior material 127 and 128 together with the electrolyte.

At this time, the electrode assembly 121 and the facings 127 and 128 may be provided with patterns 126 and 129 for contraction and relaxation, respectively. For example, the contraction and relaxation patterns 126 and 129 may be formed along the longitudinal direction or the width direction of the electrode assembly 121 and the facings 127 and 128, 129 and the second pattern 126 formed on the electrode assembly 121 may have the same directionality (refer to FIGS. 12 and 13).

Such patterns 126 and 129 can prevent or minimize the shrinkage or relaxation of the substrate itself by canceling the amount of change caused by the curvature at the time of deformation even if deformation of the bag body 110 occurs during use.

For example, when the bag body 110 is made of a soft material and deformation of the bag body 110 occurs during use, damage to the flexible battery built in the bag body 110 may be prevented do.

That is, since the amount of deformation of the substrate itself constituting the electrode assembly 121 and the facings 127 and 128 is prevented or minimized, the deformation of the bag body 110, for example, the deformation amount of the substrate itself, It is possible to prevent the electrode assembly 121 and the casing materials 127 and 128 from being damaged or deteriorated in performance.

The first pattern 129 and the second pattern 126 are disposed so that the first pattern 129 and the second pattern 126 coincide with each other in the same direction as the first pattern 129 and the second pattern 126. This is to ensure that the first pattern 129 and the second pattern 126 always have the same behavior.

In other words, when the battery 120 applied to the present invention is provided as a flexible battery, patterns 126 and 129 for shrinking and relaxing in the longitudinal direction, which are generated when the electrode assembly 121 and the casing materials 127 and 128 are bent, The electrode assemblies 121 and the cover members 127 and 128 can always maintain a uniform gap or contact state with respect to the entire length of the electrode assemblies 121 and the electrode assemblies 121, It is possible to prevent the performance of the battery from deteriorating due to uniform distribution of the electrolyte solution over the entire length.

This can be confirmed by the graph of FIG.

That is, when a force is applied to both ends of the flexible battery in an environment of a temperature of 25 ° C and a humidity of 65%, and the curvature in the bent portion is made to be 25 mm, and charging and discharging are performed 100 times, When the pattern was formed on both the electrode assembly 121 and the facings 127 and 128, the capacity (110 mAh) was reduced by about 15% compared to the capacity without the banding 130 mAh. (Example), a flexible battery having a pattern for shrinkage and relaxation only on the exterior material side showed a performance gradually falling from a capacity reduced by about 60% (52 mAh) compared to the initial capacity, and it was impossible to charge / In the case of the flexible battery having a simple plate shape in which no pattern is formed in both the casing and the electrode assembly, a capacity of about 80% reduced from the initial capacity (26 mAh) It was confirmed that charging and discharging were impossible when the deterioration occurred and exceeded 30 times (Comparative Example 2).

On the other hand, in the environment of a temperature of 25 ° C and a humidity of 65%, the middle of the length of the flexible battery was completely folded back to the original state, and the voltage in the battery was measured with time. As a result, 121 and the exterior materials 127 and 128, a change in voltage value did not occur (Example), but a flexible battery having a pattern for contraction and relaxation only on the exterior material side (Comparative Example 1) And the flexible battery (Comparative Example 2) having a simple plate-like shape in which no pattern was formed in both of the electrode assemblies and the electrode assemblies was found to be deteriorated in voltage value.

In other words, in the case where the patterns 126 and 129 for contraction and relaxation are formed so as to coincide with the facings 127 and 128 and the electrode assembly 121, even if banding occurs, the degradation of performance does not occur largely, Cracks are generated by bending or leakage of electrolyte occurs, and the performance of the battery deteriorates.

As described above, the flexible battery according to the present invention is formed such that the patterns 126 and 129 for contraction and relaxation in the longitudinal direction, which are generated when the electrode assembly 121 and the facings 127 and 128 are bent, Since the electrode assembly 121 and the facings 127 and 128 can always maintain uniform spacing or contact with the entire length thereof, the electrolyte solution sealed together with the electrode assembly 121 is uniformly distributed over the entire length, It is possible to prevent degradation of performance.

At this time, the pattern may be formed entirely or partially in the flexible battery.

For example, when the flexible battery is formed of a single cylinder and is simultaneously embedded in the lid part 114 and the rear part 112, the flexible battery can be installed in the boundary area 115 between the lid part 114 and the rear part 112 A pattern for contraction and relaxation may be formed in a direction parallel to the width direction of the rear portion 112 or the lid portion 114 (see FIG. 7).

Accordingly, even if the boundary region 115 is repeatedly bent in the process of opening and closing the upper portion of the accommodating portion S through the lid portion 114, the amount of change in length caused during bending is canceled by the pattern It is possible to prevent the flexible battery from being damaged or deteriorated in performance.

As another example, a flexible battery made up of one cylinder can be built in at least one of the front part 111 and the rear part 112 together with the bottom part 113. In this case, the flexible battery may include a front portion 111 or a rear portion (not shown) formed at a portion of the entire length that is disposed in the boundary region between the bottom portion 113 and the front portion 111, or between the bottom portion 113 and the rear portion 112 A pattern for contraction and relaxation may be formed in a direction parallel to the width direction of the electrodes 112a and 112a.

Accordingly, even if a portion disposed in the boundary region is bent, it is possible to prevent the flexible battery from being damaged or deteriorated in performance by being protected through the pattern.

The first pattern 129 and the second pattern 126 may be formed in a direction parallel to the width direction of the casing members 127 and 128 and the electrode assembly 121, 127 and 128 and the electrode assembly 121 along the longitudinal direction of the electrode assembly 121 (see FIG. 12).

The first pattern 129 and the second pattern 126 may be formed such that the first and second patterns 129 and 126 are formed at the same positions, 126 may conform to each other.

The patterns 126 and 129 may be continuously formed in a direction parallel to the width direction of the electrode assembly 121 and the facings 127 and 128 or may be formed discontinuously. 127,128, and may be partially formed with respect to a part of the length.

The crests and valleys may be formed to have arcuate cross-sections including semicircles, polygonal cross-sections including triangular or rectangular cross-sections, and cross-sections of various shapes in which arc-shaped cross-sections and polygonal cross-sections are mutually combined. Pitch and width, but they may be provided to have different pitches and widths.

In addition, the first pattern 129 and the second pattern 126 may be formed such that the intervals between adjacent horns or intervals between the valleys are the same or may be different from each other, Gaps may be provided in a combined form.

The electrode assembly 121 is encapsulated with an electrolytic solution in the casing materials 127 and 128 and includes an anode 122, a cathode 124 and a separator 123 (see FIG. 13).

However, the wireless power transmission antenna 150 may be a wireless And may be used as an antenna for receiving wireless power for receiving power.

That is, the antenna 150 for wireless power transmission according to the present invention can perform the function of an antenna for wireless power transmission or the function of an antenna for wireless power reception according to the purpose of use through one antenna.

At this time, if the inductance of the antenna 150 for wireless power transmission changes during the transmission of the power signal by the antenna 150 for wireless power transmission and another power signal transmitted from the outside is not detected, The amount of power stored in the battery 120 is consumed by adjusting the amount of power according to the load demanded by the device, thereby charging the battery of the portable electronic device.
