[0028] The embodiments will be described in detail with reference to the drawings. However, the present invention is not limited to the following description. The present invention is not limited to the above embodiments, and various changes and modifications may be made in form and detail without departing from the spirit and scope of the present invention. Therefore, the present invention is based on the following embodiments. The present disclosure should not be construed as being limited to the contents of the preceding paragraph.

[0029] In the configuration of the invention described below, the same parts or parts having similar functions are The same reference numerals are used in common between different drawings, and repeated explanations thereof will be omitted. When referring to a function, the hatch pattern may be the same and no particular symbol may be assigned.

[0030] In each figure described in this specification, the size, layer thickness, or area of ​​each component is The figures may be exaggerated for clarity and are not necessarily limited to that scale. stomach.

[0031] In this specification, ordinal numbers such as "first" and "second" are used to avoid confusion of components. The number is not a numerical limitation.

[0032] (Embodiment 1) One aspect of the present invention is a connecting member having a pipe, a spring, and a pair of pivots. The connecting member is, for example, a part of a watch-type device that is connected to a housing (also called a main body or case). Used as a spring bar to attach a band (also called a strap or belt) Hereinafter, the connecting member according to one embodiment of the present invention may be referred to as a spring bar. .

[0033] The pivot of the connection member of one aspect of the present invention has a tip portion, a flange portion, a shaft portion, and a terminal portion. The pair of pivots are electrically insulated from each other. The portion and the shaft portion are electrically conductive, and their surfaces are electrically conductive.

[0034] The pivot shaft is electrically connected to one of the pair of battery electrodes (tabs, wiring, etc.). At this time, the pair of pivots of the connecting member are insulated from each other. This prevents a pair of electrodes of the battery from becoming electrically connected. The two ends of the connecting member are connected to either of the pair of electrodes of the battery. In other words, the two ends are electrically connected to one of the batteries. It can function as a pair of terminals.

[0035] In this way, by attaching the connection member to which the battery is connected to the electronic device, The battery can be used as an auxiliary power source for an electronic device. The connecting member is attached to a pair of bearings. Power from the battery is supplied to the electronic device.

[0036] In addition, when a secondary battery is used as the battery, the battery is connected to the bearing of the electronic device via the connecting member. In this case, the electronic device itself acts as the main power source. In this case, the battery may be attached via a connecting member, and It is possible to set in advance which of the batteries in the electronic device and the battery in the device itself will be charged first. Preferably, the setting is fixed or user selectable.

[0037] The battery uses a flexible film as the exterior body and is repeatedly bent and stretched. This allows the battery and the connection part to be used suitably. A part of the material can be disposed inside the band-shaped exterior body. The appearance and fit of the exterior body are similar to those of conventional bands (straps, belts, etc.) that do not have a battery. can be made equivalent to

[0038] If a battery that cannot be bent is used, a band-shaped The battery can be placed inside the unbent part of the exterior body. There are various types of batteries, such as coin (button) type batteries, cylindrical batteries, and prismatic batteries. Ponds can be used.

[0039] Such a band-shaped power supply device can be attached to an electronic device using the above-mentioned connecting member. For example, if the battery charge level becomes low, When the battery is deteriorated, or when a primary battery is used, If an auxiliary power supply is not required, the user can simply replace the conventional spring. The stick can also be used to replace a traditional (battery-less) band. Users can freely choose between a band-type power supply unit and a conventional band depending on their purpose and preference. It can be attached to an electronic device.

[0040] The electronic device to which the connecting member and the power supply device of one aspect of the present invention can be attached has a pair of shafts. The function of detecting the potential difference between the bearings, or the function of detecting whether the pair of bearings is in a conductive or insulated state. It is preferable that the device has a function to detect that the

[0041] For example, when the connecting member of one aspect of the present invention or a conventional spring bar is not attached, The pair of bearings are insulated from each other, and each bearing is electrically floating. In addition, when the connection member according to one aspect of the present invention is attached to a battery that is not connected, When the spring bar is attached, the pair of bearings are electrically insulated. If this happens, the spring bar will be in an insulated state or a conductive (short) state, depending on the material of the spring bar. In this way, when it is detected that the pair of bearings are in a conductive state or an insulated state, It is possible to determine that the connecting member to which the battery is connected is not attached, and The electronic device can be operated using the power of another battery that the device itself has.

[0042] On the other hand, when a connection member according to one aspect of the present invention to which a battery is connected is attached, A potential difference occurs between the pair of bearings according to the battery output voltage. This potential difference is detected By doing so, it is possible to determine that the connecting member to which the battery is connected is attached. The power supplied from the battery can be used to operate electronic devices.

[0043] Below, more specific configuration examples of the connection member, power supply device, and electronic device according to one embodiment of the present invention will be described. An example of a system according to an embodiment of the present invention will be described with reference to the drawings.

[0049] The switch 35 functions as one of the user interfaces. Push, pull, turn, or slide the switch 35 up and down or forward and backward. The electronic device 30 can perform the following operations in conjunction with such operations: You can launch applications, switch between them, or perform other operations. In this example, one switch 35 is provided on the housing 31, but other switches may also be provided. It may be possible.

[0050] The lug 33 is a part to which the connecting member 10 and other components such as a spring bar are attached. Alternatively, a part of the housing 31 may function as the lug 33. The pair of lugs 33 are arranged symmetrically. The bearings 34 are provided on the opposing surfaces. At 34, the connecting member 10 can be attached.

[0051] The bearing portion 34 is inserted into the tip portion 12a of the pivot 12 of the connecting member 10, which will be described later. The bearing portion 34 has a conductive portion, and the tip portion 12a has a recess. A potential is applied.

[0052] The power supply device 20a and the power supply device 20b are used for attaching the electronic device 30 to the arm or the like. It functions as a device for wearing (band, strap, belt, etc.).

[0053] The power supply device 20a and the power supply device 20b each have a strip-shaped exterior body 21. A battery 22 is provided inside the connector 10. The connector 10 is partially separated from the exterior body 21. The battery 22 has a pair of tabs 23, each of which The spring 23 is joined to a conductive member 25.

[0054] The pair of tabs 23 of the battery 22 are electrically connected to the bearing portion 34 via the connecting member 10. This allows the battery 22 to supply power to the electronic device 30, and The electronic device 30 is then able to charge the battery 22 .

[0055] Here, two power supply devices, the power supply device 20a and the power supply device 20b, are connected to the electronic device 30. The example shown is attached to the , but either one can be attached to a normal attachment (band, belt, strap, etc.). It may be replaced with a different word (such as a "top").

[0056] [Example of connection member configuration] FIG. 1(C) shows a schematic cross-sectional view of the connection member 10 in a direction parallel to the axial direction.

[0057] The connecting member 10 includes a pipe 11 , a pair of pivots 12 , and a spring 13 .

[0058] The pivot 12 has, from the outside, a tip portion 12a, a flange portion 12b, a shaft portion 12c, and an end portion 12d. It has.

[0059] The pipe 11 is hollow and has a narrowed end. Inside 11, a spring 13 and the end portions 12d of a pair of pivots 12 are provided. The spring 13 is provided in a state where its natural length is shorter than its natural length in the natural state. The force exerts a force on the pair of pivots 12 in the outward direction.

[0060] The tip portion 12a and the flange portion 12b are portions that protrude from the pipe 11 in a natural state. In addition, the shaft portion 12c has a portion that protrudes from the pipe 11 in its natural state. When an external force is applied in the direction in which the spring 13 compresses, a part of the shaft 12c is inserted into the pipe 11. The end portion 12d has a portion that is inserted into the pipe 11 in a natural state. Here, the natural state refers to a portion where the connecting member 10 is positioned in the axial direction (longitudinal direction) of the connecting member 10. This refers to a state in which no force is being applied from the part.

[0061] The diameter of the end portion 12d is larger than the diameter of the hole at the end of the pipe 11. The diameter of the shaft portion 12c is The diameter of the hole at the end of the pipe 11 is equal to or smaller than that of the hole at the end of the pipe 11. Even if force is applied to the bot 12, the pivot 12 will not jump out of the pipe 11. It can be prevented.

[0062] The tip portion 12a is a portion that is inserted into a hole in the bearing portion 34 of the electronic device 30. The flange portion 12b is a portion that engages with a recessed portion of the bearing portion 34. In addition, the flange portion 12b engages with a part of the bearing portion 34, thereby preventing the electronic device 30 from being damaged. When the connecting member 10 is attached to the

[0063] The flange 12b is a removal tool that can be used when attaching and detaching the connecting member 10. This allows the connection member 10 to be used as a part that engages with the electronic device 30. The flange portion 12b is easily attached to or detached from the electronic device 30. The shaft portion 12c has one or more portions with a larger diameter than the shaft portion 12a. In addition, if the flange portion 12b has two or more portions with a larger diameter than the other portions, it is more convenient. For example, inserting a removal tool between the two large diameter parts is preferable. can be done.

[0064] FIG. 1(C) shows a state in which a conductive member 25 is attached to the connection member 10. The conductive member 25 has a portion that fits onto the shaft portion 12c. By joining the conductive member 25, the conductive member 25 can be attached. It is preferable that the shaft portion 12c is attached to the shaft portion 12c so as to be slidable in the axial direction.

[0065] FIG. 1(D) shows a state in which a force is applied to the pair of pivots 12 from the outside in the state shown in FIG. 1(C). 1(D) is a schematic cross-sectional view of the spring 13 in a compressed state. When the spring 13 is compressed, a part of the shaft 12c enters the inside of the pipe 11. It becomes a state.

[0066] In FIG. 1(D), the axial width of the conductive member 25 and the length of the shaft portion 12c protruding from the pipe 11 are The conductive member 25 has one end connected to a pad. The other end of the flange 12b is in contact with the end of the flange 11. ) is a state in which the pivot 12 cannot slide further inward. It can also be said that the connecting member 10 is in the most contracted state.

[0067] Also, by loosening the external force from the state shown in Figure 1(D), the state changes to that shown in Figure 1(C). At this time, since the conductive member 25 is slidably attached to the shaft portion 12c, The position of the conductive member 25 remains as shown in FIG. 1(C).

[0068] Here, in Figs. 1(C) and (D), the tip portion 12a, the flange portion 12b, and the shaft portion 12c The surface of one part of the shaft portion 12c is electrically conductive. The surface is insulating. It is marked with a circle.

[0069] When the surface of the terminal portion 12d is insulating, the spring 13 is conductive. However, the pair of pivots 12 can be electrically insulated.

[0070] Furthermore, since the end portion 12d and a part of the shaft portion 12c are insulating, the pipe 11 can be easily introduced. Even if the pair of pivots 12 have electrical conductivity, they should be electrically insulated. At this time, as shown in FIG. 1(D), when the pivot 12 is positioned at the innermost position, In this case, it is sufficient that the portion of the shaft portion 12c that comes into contact with the end of the pipe 11 has insulating properties. As shown in FIG. 1C, when the pivot 12 is positioned at the outermost position, the conductive shaft 12c It is important that the portion having the conductive member 25 comes into contact with the conductive member 25.

[0071] The surface of the end of the pipe 11 and the surface of the end of the conductive member 25 are conductive. 1(C), the conductive member 25 and the pipe 11 come into contact with each other. Sometimes, a pair of conductive members 25 may be electrically shorted. As shown in FIG. 1(E), an insulating buffer material 14 is provided between the conductive member 25 and the pipe 11. The buffer material 14 is preferably a ring-shaped material such as rubber or plastic. The following structures can be used.

[0072] Here, the pipe 11, pivot 12 and spring 13 are typically made of metal such as stainless steel. When such metals are used, a part or the whole of the surface can be Insulation methods include oxidizing the surface and forming an insulating film by plating. Alternatively, the pipe 11, pivot 12, and spring 1 may be covered with insulating resin. An insulating material such as resin can be used for the conductor 3. When resin is used, the surface For example, a conductive film may be formed by plating or the like. There are ways to achieve this.

[0073] Here, the configuration of the connecting member 10 is not limited to the configuration shown in FIG. 1(C) etc., and may be a configuration in which a pair of pivots 1 2 is electrically insulated. Other examples of the connection member 10 will be described below. .

[0074] The pivot 12 of the connecting member 10 shown in FIG. 2(A) has a shaft portion 12c having a surface and an end The surfaces of the portions 12d and 12e are electrically conductive. The surface of the pipe 11 and the opening are insulating. 13a, spring 13b) and a buffer material 15 therebetween. The buffer material 15 has an insulating surface. It has sexuality.

[0075] In FIG. 2(A), springs 13a and 13b are separated by buffer material 15. The pipe 11, which the springs 13a and 13b contact, has an insulating surface. Therefore, the spring 13a and the spring 13b are electrically insulated from each other. Even if the bots 12 are electrically conductive, they are electrically connected via the springs 13a and 13b. These are electrically isolated from each other so that they cannot be shorted together.

[0076] In addition, by adopting such a configuration, the entire surface of the shaft portion 12c of the pivot 12 is made conductive. This increases the contact area between the shaft portion 12c and the conductive member 25. This allows the contact resistance therebetween to be reduced.

[0077] In FIG. 2(B), instead of the buffer material 15 shown in FIG. 2(A), the pipe 11 has a partition wall 11a. The partition wall 11a is located at the center of the pipe 11, and the spring 13a and the It has the function of separating Ne13b.

[0078] FIG. 2(C) shows a case where the surface of the pipe 11 and the surface of the spring 13 are both insulating. An example of this case is shown.

[0079] Here, in the above description, the conductive member 25 comes into contact with the shaft portion 12c of the pivot 12, and thus the conductive member Although the configuration in which the conductive member 25 and the pivot 12 are electrically connected has been shown, the present invention is not limited to this. Any configuration may be used as long as the conductive member 25 and the tip end 12a of the pivot 12 are electrically connected.

[0080] FIG. 2(D) shows a pipe 11 having a pair of conductive portions 11b and a pair of conductive portions 11b. The pair of portions 11b are electrically insulated from each other. The conductive member 25 is fitted into the portion 11b. Therefore, the pivot 12 and the conductive member 25 are electrically connected via the portion 11b. do.

[0081] Here, as shown in FIG. 2(D), the portion 11b and the portion 11c have a screw structure. It is preferable that they are fastened together by this method. However, they may also be joined together with an adhesive or the like.

[0082] FIG. 2(D) shows an example in which the springs 13a and 13b are separated by a buffer material 15. However, they may be separated by a partition wall 11a of the pipe 11, as in FIG. 2(B). As shown in FIG. 2(E), a spring 13 having an insulating surface is provided without a buffer material 15. This may also be configured as follows.

[0083] The above is the description of the connecting member.

[0100] This concludes the explanation of the battery.

[0101] [Conductive material] Hereinafter, a conductive member for electrically connecting the electrode (tab) of the battery and the connection member 10 will be described. An example of the functional member 25 will be described.

[0102] FIG. 4(A) is a schematic diagram showing the conductive member 25 and a part of the shaft portion 12c of the pivot 12. Here, an example in which the conductive member 25 is connected to the shaft portion 12c is shown. By increasing the diameter of the conductive member 25, it is possible to connect the conductive member 25 to a part of the pipe 11 as shown in FIG. 2(D) and the like. It may also be configured so that the two are connected to each other.

[0103] The conductive member 25 shown in FIG. 4(A) includes a cylindrical portion having a hole into which the shaft portion 12c is fitted, In the example shown in FIG. 4(A), the conductive member 25 has legs that are joined to tabs of the battery, etc. The cross section of the cylindrical portion is annular, and the cross section of the shaft portion 12c is circular. As shown by the arrow in the figure, the conductive member 25 and the shaft portion 12c are rotated in the direction of rotation with respect to the shaft portion 12c. The shaft portion 12c can be configured to be rotatable and slidable in the extending direction of the shaft portion 12c.

[0104] FIG. 4(B) shows an example in which the cross section of the shaft portion 12c has a shape in which a part of a circle is cut out. The shape of the hole in the conductive member 25 is also adjusted to fit the shaft portion 12c. By adopting such a configuration, the conductive member 25 and the shaft portion 12 and c are fixed in the rotation direction and are slidable in the extension direction of the shaft portion 12c. The member 25 can be connected to the shaft portion 12c.

[0105] As shown in FIG. 4(C), the cross section of the shaft portion 12c has a substantially polygonal shape. FIG. 4(C) shows an example in which the cross section of the shaft portion 12c is a rectangle with rounded corners. With this configuration, the conductive member 25 and the shaft portion 12c are fixed in the rotation direction. The conductive member 25 and the shaft portion 12c are connected together in a state where they are slidable in the extending direction of the shaft portion 12c. It can be connected.

[0106] As shown in FIGS. 4(A), (B), and (C), a part of the conductive member 25 is formed into a cylindrical shape. This is preferable because it increases the contact area between the conductive member 25 and the shaft portion 12c. When the conductive member 25 is formed in a cylindrical shape, for example, a material that shrinks due to heat or the like is used for the conductive member 25. The material is inserted from the tip end 12a side in a state where the diameter is larger than that of the flange portion 12b. Alternatively, a strip-shaped member may be wound around the shaft portion 12c. The cylindrical portion of the conductive member 25 may be formed by bonding the conductive member 25 to the cylindrical portion.

[0107] FIG. 4(D) shows a conductive member 25 having a cylindrical shape with a part cut out (the cross section may be arc-shaped). In Fig. 4(D), a part on the opposite side of the leg is cut off. By adopting such a configuration, the shaft portion 12c and the conductive This allows the member 25 to be easily attached and detached.

[0108] In FIG. 4(D), the conductive member 25 and the shaft portion 12c are rotated in the rotation direction relative to the shaft portion 12c. The shaft portion 12c is connected in a slidable state in the extending direction of the shaft portion 12c.

[0109] FIG. 4(E) shows an example in which the position of the notched portion of the conductive member 25 is different from that of FIG. 4(D). This shows:

[0110] Also, Fig. 4(F) and Fig. 4(G) show examples in which the cross section of the shaft portion 12c is not circular. With this configuration, the conductive member 25 and the shaft portion 12c are fixed in the rotation direction. The conductive member 25 and the shaft 12c are fixed to each other and are slidable in the extending direction of the shaft 12c. In addition, the conductive member 25 and the shaft portion 12c can be easily detached from each other. can be done.

[0111] The above is the description of the conductive member.

[0112] [Power supply configuration example] An example of a power supply device that can be attached to an electronic device will be described below. In particular, a power supply device applicable to a wristwatch-type electronic device 30 will be described.

[0114] The power supply device 20a includes a connection member 10, a battery 22, an exterior body 21a, an exterior body 21b, and It has a buckle 51 etc. A part of the connection member 10 protrudes from the power supply device 20a.

[0115] As shown in FIG. 5(B), the battery 22 is sandwiched between the exterior body 21a and the exterior body 21b. A space for installing the battery 22 is secured on the inner surfaces of the exterior body 21a and the exterior body 21b. This allows the area where the battery 22 is provided to be separated from the area where the battery 22 is provided. The thickness can be made uniform between the areas where the mask is not installed, making the wearing comfort good. This can be done.

[0116] The exterior body 21a and the exterior body 21b may be a normal band (without a battery) or the like. Similar materials can be used, such as rubber, leather, cloth, metal, resin, etc. In particular, when rubber or resin is used, molding is easy, which is preferable. stomach.

[0117] 6(A) and 6(B) show perspective schematic views of the power supply device 20b that is paired with the power supply device 20a. The power supply device 20b includes a connection member 10, a battery 22, an exterior body 21c, and an exterior body 21. d etc.

[0118] The exterior body 21c and the exterior body 21d have a plurality of holes 52 instead of the buckle 51, which is different from the above. It is different from the exterior body 21a and the exterior body 21b.

[0119] In this way, power supply unit 20a and power supply unit 20b are not limited to conventional spring bars and conventional (battery) A combination of a band, belt, strap, or other attachment (not having a strap, etc.), It is possible to make the shape such that there is almost no difference in appearance.

In addition to the function as a power source, it can also function as an auxiliary power source or a main power source for the electronic device 30. can be done.

[0121] By using the power supply device 20a or 20b according to one embodiment of the present invention, a separate auxiliary This increases convenience as there is no need to carry a power source. Since there is no need to connect a separate auxiliary power supply to the slave device 30, it can be used even with the auxiliary power supply connected. It is possible to realize an electronic device that is not bulky and allows easy movement even when worn. There is no need to connect the auxiliary power supply with a connector, so there is no risk of the auxiliary power supply coming off and slipping off. In addition, since there is no need to provide a terminal for inserting the connector in the electronic device 30, This allows for improved waterproofing and allows for the realization of electronic devices with a highly aesthetic design.

[0122] Here, the battery 22 included in the power supply device 20a and the power supply device 20b is enclosed in its exterior body 26. By providing the surface with an uneven shape, the reliability of the battery 22 can be improved when the battery 22 is repeatedly bent. It is possible.

[0123] FIG. 7(A) shows an example in which the surface of the exterior body 26 has a mesh-like embossed pattern. In addition, in FIG. 7(B), the surface of the exterior body 26 has a stripe-shaped embossed pattern. An example is shown.

[0124] If the exterior body 26 has an uneven shape, when the battery 22 is bent, the battery 22 is located on the outside of the bend. The outer casing 26 is configured such that the convex and concave portions located on the inside of the bend expand, and the convex and concave portions located on the inside of the bend contract. This allows the stress applied to the exterior body 26 to be alleviated.

[0125] This concludes the description of the power supply device.

[0126] [Example of electronic device configuration] The following describes more specific examples of electronic devices that can receive power from the power supply device described above. An example of such a configuration will be described.

Here, the power supply voltage of the power supply device 20 is supplied to the control unit 61 and the functional circuit 63. The power supply may have a function of converting the power supply voltage into a voltage suitable for use in the power supply.

The exterior covering the connection member 10, the conductive member 25, and the tab 42 is also shown. The body 21 is shown in dashed lines.

[0135] The bearing portion 34 provided on the lug 33 is connected to the terminal 71 which engages with the tip portion 12a of the connecting member 10. The terminal 71 is electrically connected to a wiring 72.

[0136] 8(B), a part of the lug 33 is provided with a flange 12b of the connecting member 10 for engagement therewith. It is preferable that a recess is formed so that the connection member 10 can be securely connected. This can improve quality.

[0137] In FIG. 8B, the power supply control unit 62 is in the form of an IC chip and is mounted on a substrate 75. The substrate 75 may be, for example, a PCB. 4 and the substrate 75 are electrically connected by wiring 72.

[0142] Here, the bearing portion 34 has a seal material that prevents water and dust from entering the housing 31. In particular, if water comes into contact with the terminal 71 of the bearing portion 34, the battery 22 may short-circuit. However, since there is a risk of a large current flowing, it is effective to provide a seal.

[0146] In the drawings attached to this specification, the components are classified by function and are separated into blocks independent of each other. Although the block diagram is shown as a block, the actual components are completely separated by function. This is difficult, and one component may be involved in multiple functions.

[0155] The power supply control unit 62 has a function of controlling the charging and discharging of the battery 65 and the battery 22 . The power supply control unit 62 also controls the remaining battery power of the battery 65 and the battery 22. It is preferable that the unit 61 has a function of transmitting the information to the unit 61.

[0156] The sensor 64 detects the potential difference between the pair of bearings 34 and outputs the information to the control unit 61. For example, a comparison circuit or the like is used to calculate a digital value corresponding to the potential difference between the bearing portions 34. A signal corresponding to the potential difference between the bearings 34 may be output to the control unit 61. In this case, the sensor 64 and the control unit 61 may be configured to output an analog signal indicating the temperature of the sensor 64 to the control unit 61. It is preferable to use an analog-to-digital conversion circuit between the control unit 61 and the analog-to-digital conversion circuit.

[0165] In addition, the control unit 61 and ICs of other components have an oxidized layer in the channel forming region. It is also possible to use transistors that use semiconductors and have extremely low off-state current. Since the off-state current of the transistor is extremely low, the transistor can be used as a memory element. Used as a switch to hold the charge (data) that has flowed into the functioning capacitive element This allows the data to be retained for a long period of time. By using it as a register or cache memory, the control unit 61 can be operated only when necessary, and other In this case, the information of the immediately preceding process is saved in the memory element, so that the normally off-line computer This allows for low power consumption of the electronic device 30.

As a power saving function, when it is detected that there is no input to the electronic device 30 for a certain period of time, the control unit 61 The clock frequency is lowered or the clock input is stopped, and the operation of the control unit 61 itself is stopped. It stops the operation of the auxiliary memory, and reduces the power supplied to each component. These functions include reducing power consumption by reducing the power consumption. It can be performed by control unit 62 alone or in conjunction with control unit 61 .

[0172] [Battery] The battery 65 and the battery 22 each include, for example, one or more primary batteries or secondary batteries. Examples of secondary batteries that can be used for the battery 65 include lithium ion secondary batteries and The battery 65 may be a lithium ion polymer secondary battery. In addition, a protection circuit may be provided to prevent overcharging and overdischarging.

Metal films are easy to emboss and have excellent mechanical properties. When concave or convex portions are formed by embossing, the surface area of ​​the film exposed to the outside air increases. Therefore, it has excellent heat dissipation effect.

[0178] Especially for laminated bags, metal film with concave and convex parts formed by embossing is used. When a laminated bag having the above structure is used, the strain caused by the stress applied to the laminated bag is reduced. As a result, the laminated bag does not tear when the secondary battery is bent. This is preferable because it can effectively reduce problems such as the sagging of the paper.

[0215] [Example of how the system works] Next, the operation of the system 50 shown in FIG. 9(A) will be described.

[0216] [Operation method example 1] 10 is a flowchart showing the operation of the system 50. This is an example of a case where the power source is operated to use either the power of the power supply 61 or the battery 65. The following operations are mainly executed by the control unit 61.

[0217] First, the operation starts in step S00. For example, when the electronic device 30 is turned on, Or, the system 50 may be activated by a user. Alternatively, the bearing portion 34 may be fitted with a connecting member 10 or a conventional spring bar or other member. The operation may be initiated when an operation such as inserting or removing the device is performed.

[0218] Next, in step S01, information on the potential of the pair of bearing portions 34 (hereinafter also referred to as potential information) is More specifically, the control unit 61 acquires information on the potential between the pair of bearings 34. The sensor 64 then controls the control unit 61 to obtain the potential. Output information.

[0219] Next, in step S02, the pair of bearings 34 are in a short-circuited state or an insulated state. If it is determined that the pair of bearings 34 are in a short-circuited state or an insulated state, In this case, the process proceeds to step S05, and the pair of bearing portions 34 is in a short-circuited state or an insulated state. If it is determined that there is no such information, the process proceeds to step S03.

[0220] Step S02 determines whether the power supply device 20 is connected to the electronic device 30. corresponds to a step.

[0221] Specifically, when the potential difference between the pair of bearing portions 34 is 0 V or close to 0 V, It is determined that the pair of bearings 34 is in a short-circuited state or an insulated state. The power supply unit 20 including at least the battery 22 is not connected to the power supply unit 34. Cut.

[0222] On the other hand, when the potential difference between the pair of bearing portions 34 is, for example, 0.5 V or more, or 1 V or more, In this case, it is determined that there is no short circuit or insulation. It can be determined that the power supply device 20 is connected to the unit 34.

[0223] Next, in step S03, the potential difference between the pair of bearing portions 34 is determined to be within a predetermined range of potential difference. If it is within the predetermined range of the potential difference, the process proceeds to step S04. On the other hand, if the potential difference is not within the predetermined range, the process proceeds to step S05.

[0224] Step S03 corresponds to a step of checking the remaining capacity of the battery 22 of the power supply device 20. Here, the remaining capacity of the battery 22 is determined based on the output voltage within a range defined by the rated voltage range, etc. For example, within the rated voltage range, the voltage of the fully charged battery can be measured. The voltage in the discharged state can be set to 100%, the voltage in the discharged state can be set to 0%, etc. In this case, step S In the case of 03, the potential difference between the pair of bearing parts 34 is 0% or more and less than 5% within the range of the rated voltage. When the potential difference is 0% or more and less than 3%, the remaining charge of the battery 22 is sufficient. It can be determined that it is not.

[0225] Step S03 is also performed to check whether the output voltage of the battery 22 exceeds the assumed voltage range. This step also corresponds to excluding the output voltage of the battery 22 from the expected voltage. If the voltage is too large, there is a risk that each component in the electronic device 30 may fail. The potential difference between the pair of bearing portions 34 is set to a predetermined maximum value that can be input to the electronic device 30. If the voltage value is exceeded, it is determined that the potential difference is not within the predetermined range.

[0226] In this case, the remaining capacity of the battery 22 is measured using the potential difference between the pair of bearings 34. However, the present invention is not limited to this, and measurement may be performed using, for example, the amount of current or the amount of power.

[0227] Next, in step S04, it is determined whether or not to use the power supplied from the bearing portion 34. If it is to be used, the process proceeds to step S06. If it is not to be used, the process proceeds to step S07. Proceed to S05.

The control unit 61 controls the power supply control unit 62 so that the power supply control unit 62 outputs the signal to the Migrate.

[0230] In step S06, the electronic device 30 is driven using the power supplied from the pair of bearings 34. Specifically, the battery 22 of the power supply device 20 supplies power to the connection member 10 and the The control unit 61 outputs the power input via the bearing unit 34 to each component. controls the power supply control unit 62. After that, the process proceeds to step S07.

[0231] In step S07, the operation ends.

[0232] This concludes the description of the flow shown in FIG.

[0235] First, the operation starts in step S10.

[0236] Subsequently, in step S11, it is determined whether or not the device is in a power receiving state. It is determined whether the power receiving unit 66 is receiving power. If it is receiving power, The process proceeds to step S12, and if the mobile phone is not in a power receiving state, the process proceeds to step S18.

[0237] In step S12, the potential information is acquired.

[0238] In step S13, it is determined whether the pair of bearings 34 are in a short-circuited state or an insulated state. If it is determined that the pair of bearings 34 are in a short-circuited state or an insulated state, In this case, the process proceeds to step S17, and if the pair of bearing portions 34 are in a short-circuited state or an insulated state, If it is determined that there is no such file, the process proceeds to step S14.

[0239] In step S14, it is determined whether the potential difference between the pair of bearing portions 34 is smaller than a predetermined potential difference. If the potential difference is smaller than the predetermined potential difference, the process proceeds to step S15. If the potential difference is equal to or greater than the predetermined potential difference, the process proceeds to step S17.

[0240] Step S14 checks whether the battery 22 of the power supply device 20 is fully charged. For example, the predetermined potential difference in step S14 is Battery 22 is fully charged (output voltage is 100% within the rated voltage range). It can be a corresponding potential difference.

[0241] In step S15, power is output to the pair of bearings 34, thereby Specifically, the power supplied from the power receiving unit 66 is output to the pair of bearing units 34. The control unit 61 controls the power supply control unit 62 so that the pair of axes A potential difference is applied to the receiving portion 34 to charge the battery 22. The battery 22 can be charged via the device 10. Then, the process proceeds to step S16. do.

[0242] Step S15 continues until the battery 22 is fully charged or in a state close to that. Specifically, the potential difference between the pair of bearing portions 34 corresponds to the fully charged state of the battery 22. Charging is completed when the potential difference is equal to or greater than 95% of the corresponding potential difference. The potential difference is less than 100% or less than 95% battery charge. If the potential difference is equal to 0.5 V, charging continues.

[0243] In step S16, it is determined whether or not charging of the battery 65 is complete. If the charging of the battery 65 is completed, the process proceeds to step S18. If charging of the battery 5 is not completed, the process proceeds to step S17.

[0244] Specifically, when the charge state of the battery 65 is fully charged or 95% or more, On the other hand, if the battery 65 is less than 100% charged, If the battery level is below 95% or 95%, it is determined that charging is not complete.

[0245] In step S17, the battery 65 is powered up by outputting power to the battery 65. Specifically, the power supplied from the power receiving unit 66 is output to the battery 65. Then, the control unit 61 controls the power supply control unit 62. After that, the process proceeds to step S18.

[0246] Step S17 is the same as step S15 in that it is determined whether the battery 65 is fully charged or not. This continues until the neighboring state is reached.

[0247] In step S18, the operation ends. At this point, the battery 22 and the battery 65 This means that both devices have completed charging.

[0248] The above is the explanation of the second example of the operation method.

[0249] [Operation method example 3] 12 is a flowchart showing the operation of the system 50. 12 shows the flow of the operation of charging the battery 65. This is an example of a case where charging is performed first. The following operations are mainly executed by the control unit 61.

[0250] First, the operation starts in step S20.

[0251] Next, in step S21, it is determined whether or not the device is in a power receiving state. If the power is received, the process proceeds to step S22, and if the power is not received, the process proceeds to step S27. do.

[0252] In step S22, the battery 65 is powered up by outputting power to the battery 65. Specifically, the power supplied from the power receiving unit 66 is output to the battery 65. Then, the control unit 61 controls the power supply control unit 62. After the charging is completed, the process proceeds to step S23. do.

[0253] In step S23, the potential information is acquired.

[0254] In step S24, it is determined whether the pair of bearings 34 are in a short-circuited state or an insulated state. If it is determined that the pair of bearings 34 are in a short-circuited state or an insulated state, In this case, the process proceeds to step S27, and if the pair of bearing portions 34 are in a short-circuited state or an insulated state, If it is determined that there is no such file, the process proceeds to step S25.

[0255] In step S25, it is determined whether the potential difference between the pair of bearing portions 34 is smaller than a predetermined potential difference. If the potential difference is smaller than the predetermined potential difference, the process proceeds to step S26. If the potential difference is equal to or greater than the predetermined potential difference, the process proceeds to step S27.

[0256] The above can be applied to the criteria for step S25.

[0257] In step S26, power is output to the pair of bearings 34, thereby After charging is completed, the process proceeds to step S27.

[0258] In step S27, the operation ends. At this point, the battery 22 and the battery 65 This means that both devices have completed charging.

It is more preferable that the content of the conductive additive with respect to the total amount of the positive electrode active material layer 502 is 1 wt %. The content is preferably from 1 wt % to 10 wt %, and more preferably from 1 wt % to 5 wt %.

[0321] When the positive electrode active material layer 502 is formed by the coating method, the positive electrode active material, the binder, and the conductive additive are mixed.

[0322] [Negative electrode] The negative electrode 515 is composed of a negative electrode current collector 505 and a negative electrode active material layer 5 formed on the negative electrode current collector 505. 16, one side of a sheet-shaped (or strip-shaped) negative electrode current collector 505 One negative electrode 515 having a negative electrode active material layer 506 on one side, and one negative electrode 515 having a negative electrode active material layer 506 on both sides. Although an example in which one negative electrode 515 is provided is shown, one embodiment of the present invention is not limited to this. It is also possible to use only the negative electrode 515 having the negative electrode active material layer 506 on one surface of the electrode 505. In this case, the negative electrode current collectors 505 are arranged so that the surfaces thereof not having the negative electrode active material layers 506 are in contact with each other. This allows the formation of a contact surface with less friction, and reduces the stress when the secondary battery 102 is bent. In addition, the negative electrode having the negative electrode active material layer 506 on both sides of the negative electrode current collector 505 is preferable. Alternatively, only the negative electrode 515 may be used. This allows the capacity of the secondary battery 102 to be increased. By increasing the number of negative electrodes 515 included in the secondary battery 102, The capacity of the secondary battery 102 can be increased.

[0323] The negative electrode current collector 505 is made of metals such as stainless steel, gold, platinum, iron, copper, titanium, and the like, and It is recommended to use a material that has high conductivity and does not alloy with carrier ions such as lithium, such as an alloy of In addition, heat-resistant materials such as silicon, titanium, neodymium, scandium, and molybdenum can be used. An aluminum alloy containing an element that improves the resistance can be used. 05: foil, plate (sheet), mesh, punched metal, expanded metal, etc. The negative electrode current collector 505 has a thickness of 5 μm or more and 30 μm or less. It is also preferable to use graphite or the like on the surface of the negative electrode current collector 505. An undercoat layer may be provided.

[0324] The negative electrode active material layer 506 contains, in addition to the negative electrode active material, a binder ( The negative electrode active material layer 506 may contain a binder, a conductive additive for increasing the conductivity of the negative electrode active material layer 506, and the like.

[0325] The negative electrode active material is a material that can dissolve and deposit lithium or insert and extract lithium ions. The material of the negative electrode active material layer 506 is not particularly limited as long as it is a material. In addition to lithium phosphate, examples include carbon-based materials and alloy-based materials that are common in the field of energy storage.

[0326] Lithium metal has a low redox potential (-3.045 V vs. the standard hydrogen electrode) and is lightweight. and high specific capacity per volume (3860mAh / g and 2062mAh / cm, respectively). 3 ) is therefore preferable.

[0327] Carbon materials include graphite, easily graphitizable carbon (soft carbon), and non-graphitizable carbon (hard carbon). carbon nanotubes, graphene, carbon black, etc. .

[0328] As graphite, mesocarbon microbeads (MCMB), coke-based artificial graphite, Examples of the graphite include artificial graphite such as titanium-based artificial graphite, and natural graphite such as spheroidized natural graphite.

[0329] When lithium ions are inserted between the layers of graphite (the formation of lithium-graphite intercalation compounds), Sometimes), it shows a potential as low as that of lithium metal (0.1 to 0.3 V vs. Li / L i + This allows lithium-ion batteries to exhibit high operating voltages. Graphite has a relatively high capacity per unit volume, small volume expansion, is inexpensive, and is a lithium It is preferable because it has advantages such as higher safety compared to metals.

[0330] As a negative electrode active material, it can carry out charge-discharge reactions by alloying and dealloying reactions with lithium. Possible alloy materials or oxides can also be used. In this case, examples of alloy materials include Mg, Ca, Al, Si, Ge, Sn, and Pb. , Sb, Bi, Ag, Au, Zn, Cd, Hg, In, etc. These elements have a large capacity compared to carbon, and silicon in particular has a theoretical capacity The capacity is dramatically high at 4200mAh / g. Therefore, using silicon as the negative electrode active material As alloy materials using such elements, for example, Mg2Si, Mg2 Ge, Mg2Sn, SnS2, V2Sn3, FeSn2, CoSn2, Ni3Sn2, C u6Sn5, Ag3Sn, Ag3Sb, Ni2MnSb, CeSb3, LaSn3, La 3Co2Sn7, CoSb3, InSb, SbSn, etc.

[0332] In addition, the negative electrode active material is a composite nitride of lithium and transition metals, which has a Li3N structure. つLi (3-x) M x N (M=Co, Ni, Cu) can be used. For example, Li 2.6 Co 0.4 N3 has a large charge / discharge capacity (900mAh / g, 1890mAh / cm 3 ) and is preferred.

[0333] When a composite nitride of lithium and transition metals is used, lithium ions are included in the negative electrode active material, As a positive electrode active material, materials that do not contain lithium ions, such as V2O5 and Cr3O8, are used. In addition, when a material containing lithium ions is used as the positive electrode active material, However, by first removing the lithium ions contained in the positive electrode active material, As the substrate, a complex nitride of lithium and a transition metal can be used.

[0334] In addition, a material that undergoes a conversion reaction can also be used as the negative electrode active material. For example, lithium oxides such as cobalt oxide (CoO), nickel oxide (NiO), and iron oxide (FeO) A transition metal oxide that does not undergo an alloying reaction with the metal may be used as the negative electrode active material. Further materials that can react include Fe2O3, CuO, Cu2O, RuO2, Cr2 Oxides such as O3, CoS 0.89 , sulfides such as NiS and CuS, Zn3N2, Cu3N, Nitrides such as Ge3N4, phosphides such as NiP2, FeP2, CoP3, FeF3, BiF 3. Since the potential of the above fluorides is high, they are often used as positive electrode active materials. It may be used.

[0335] When the negative electrode active material layer 506 is formed by a coating method, the negative electrode active material and the binder are mixed. A negative electrode paste (slurry) is prepared, applied onto the negative electrode current collector 505, and dried. A conductive additive may be added to the negative electrode paste.

[0336] Graphene may be formed on the surface of the negative electrode active material layer 506. When the material is silicon, the charge-discharge cycle causes the charge-discharge cycle to Since the change in area is large, the adhesion between the negative electrode current collector 505 and the negative electrode active material layer 506 decreases, and the charging The battery characteristics deteriorate due to discharge. When graphene is formed on the surface, the volume of silicon changes during the charge / discharge cycle. Even if the negative electrode current collector 505 and the negative electrode active material layer 506 are not adhered to each other, a decrease in the adhesion between the negative electrode current collector 505 and the negative electrode active material layer 506 can be suppressed. This is preferable because it reduces the deterioration of the battery characteristics.

[0337] In addition, a coating of oxide or the like may be formed on the surface of the negative electrode active material layer 506. The coating formed by the decomposition of the electrolyte releases the amount of charge consumed during its formation. In contrast, a film of oxide or the like is formed on the negative electrode active material in advance, and irreversible capacity is formed. By providing the electrode on the surface of the porous layer 506, it is possible to suppress or prevent the occurrence of irreversible capacitance. do.

[0338] The coating that coats the negative electrode active material layer 506 may contain niobium, titanium, vanadium, tantalum, or the like. Ta, tungsten, zirconium, molybdenum, hafnium, chromium, aluminum or silicon oxide film, or a film containing one of these elements and lithium Such a coating is not susceptible to damage caused by the decomposition products of conventional electrolytes. This film is sufficiently dense compared to the coating formed on the outermost surface.

[0339] For example, niobium oxide (Nb2O5) has an electrical conductivity of 10 -9 Low S / cm and high Therefore, the niobium oxide film prevents the electrochemical decomposition reaction between the negative electrode active material and the electrolyte. On the other hand, the lithium diffusion coefficient of niobium oxide is 10 -9 cm 2 / sec, and high It has high lithium ion conductivity, which allows lithium ions to pass through. Silicon oxide or aluminum oxide may also be used.

[0340] The film that covers the negative electrode active material layer 506 can be formed by, for example, a sol-gel method. The sol-gel method is a method in which a solution of metal alkoxides or metal salts is subjected to a hydrolysis reaction. This method involves forming a gel that has lost its fluidity through a polycondensation reaction, and then baking this gel to form a thin film. The sol-gel method is a method for forming thin films from a liquid phase, so the raw materials must be homogenized at the molecular level. Therefore, the raw material of the metal oxide film at the solvent stage can be mixed with a negative electrode active material such as graphite. By adding a binder, the active material can be easily dispersed in the gel. A coating can be formed on the surface of the negative electrode active material layer 506. By using the coating, This can prevent a decrease in the capacity of the battery.

Nonwoven fabrics such as glass fiber and gas A membrane made of a composite of lath fiber and polymer fiber may also be used.

[0342] [Electrolyte] The electrolytic solution 504 is an electrolyte in which carrier ions can move and A material containing lithium ions is used. Typical examples of electrolytes include LiPF6, LiClO4, LiAsF6, LiBF4, LiCF3SO3, Li(CF3SO2)2 N, Li(C2F5SO2)2N, Li(SO2F)2N, etc. The electrolytes may be used alone or in any combination and ratio of two or more. Good too.

[0343] The solvent of the electrolytic solution 504 is a material in which carrier ions can move. The solvent for the liquid is preferably an aprotic organic solvent. Typical examples of the aprotic organic solvent are: Examples include ethylene carbonate (EC), propylene carbonate, and dimethyl carbonate. diethyl carbonate (DEC), ethyl methyl carbonate (EMC), γ-butyl These include lactone, acetonitrile, dimethoxyethane, and tetrahydrofuran. In addition, a polymer that can be gelled as a solvent for the electrolyte can be used. By using materials, or adding polymer materials to the electrolyte for gelation, leakage etc. can be reduced. This improves safety against battery damage. It also makes it possible to make the storage battery thinner and lighter. Representative examples of molecular materials are silicone gel, acrylic gel, acrylonitrile gel, poly Polyethylene oxide gel, polypropylene oxide gel, fluorine polymer gel In addition, ionic liquids (solvents at room temperature) that are flame-retardant and non-volatile are used as solvents for electrolytes. By using one or more molten salts, the internal temperature of the battery can be reduced by an internal short circuit or overcharging. Even if the temperature rises, the battery can be prevented from exploding or catching fire. Ionic liquids are salts in a state where cations and The ionic liquid contains ethylmethylimidazolium (EMI) cation and anion. Ionic liquids containing methyl methyl piperidinium (PP) 13 ) Click Examples include ionic liquids containing ions.

[0344] [Exterior body] There are various types of secondary battery structures, but in this embodiment, the shape of the exterior body 507 is The film used to form the exterior body 507 is a metal film ( Aluminum, stainless steel, nickel steel, etc.), plastic film made from organic materials , hybrids containing organic materials (such as organic resins and fibers) and inorganic materials (such as ceramics) Material films, carbon-containing inorganic films (carbon films, graphite films, etc.) A single layer film selected from the above or a laminated film made up of a plurality of these is used. The rubber is easy to emboss, and when recesses or protrusions are formed by embossing, the outer Since the surface area of ​​the exterior body 507 that comes into contact with the air increases, the heat dissipation effect is excellent.

[0345] In addition, when the shape of the secondary battery 102 is changed by applying an external force, the shape of the secondary battery 102 When external bending stress is applied to the exterior body 507, a part of the exterior body 507 is deformed or broken. By forming a recess or a protrusion on the exterior body 507, Therefore, the strain caused by the stress applied to the secondary battery 10 can be alleviated. This can improve the reliability of 2. Note that strain is the change in the length of an object relative to its reference length (initial state). It is a measure of deformation that indicates the displacement of a material point in an object. This reduces the effect of strain caused by applying external force to the storage battery to within an acceptable range. Therefore, it is possible to provide a highly reliable electricity storage unit.

[0346] The above is a description of the configuration example.

[0347] [Example of manufacturing method] An example of a method for manufacturing the secondary battery 102 will be described below.

[0348] [Prepare the positive electrode and cover it with a separator] First, a positive electrode 511 having a positive electrode active material layer 502 formed thereon is placed on a separator 503 ( See Figure 17(A). In Figure 17(A), the slits are formed to create a meandering shape. 5 shows an example in which the positive electrode current collector 501 has positive electrode active material layers 502 on both sides.

[0349] By forming a slit in the positive electrode current collector 501, when the secondary battery 102 is bent, It is possible to prevent the positions of the ends of the multiple current collectors from shifting. This can reduce the tension applied to the thin current collector.

[0350] In addition, when the negative electrode 515 is superimposed on the negative electrode 515 in a later step, the region 5 that overlaps with the slit of the negative electrode 515 The positive electrode active material layer 502 is not provided on the negative electrode 515. When the positive electrode active material layer 502 is provided on the surface 511a, the negative electrode active material is formed in the region overlapping with the positive electrode active material layer 502. The substance layer 506 is absent, which may cause problems during the battery reaction. Carrier ions emitted from the positive electrode active material layer 502 are introduced into the negative electrode active material layer 506 closest to the slit. As a result, there is a risk that carrier ions will be concentrated in the negative electrode active material layer 506. Therefore, the positive electrode active material layer 502 is not provided in the region 511a that overlaps with the slit of the negative electrode 515. Therefore, the deposition of carrier ions into the negative electrode active material layer 506 can be suppressed.

[0351] Next, the separator 503 is folded along the dotted line in FIG. 17(A), and the separator 50 3 sandwiches the positive electrode 511. Next, the outer peripheral portion of the separator 503 on the outside of the positive electrode 511 is joined. The separator 503 is formed in a pouch shape (see FIG. 17(B)). The outer periphery may be joined using an adhesive, ultrasonic welding, or heat fusion. It may also be carried out by

[0352] In this embodiment, polypropylene is used as separator 503, and separator 50 The outer periphery of the 3 is bonded by heating. The bonded portion 503a is shown in FIG. 17(B). The positive electrode 511 can be covered with a separator 503. The separator 503 is a positive electrode active material. It is only necessary to form the layer so as to cover the substance layer 502 , and it is not necessary to cover the entire positive electrode 511 .

[0353] In addition, in FIGS. 17(A) and (B), the separator 503 is folded. The embodiment is not limited to this. For example, the positive electrode 511 is sandwiched between two separators. In this case, the joint portion 503a may be formed so as to surround most of the four sides.

[0354] The outer periphery of the separator 503 may be joined intermittently or at regular intervals. The bonding may be in the form of dots.

[0355] Alternatively, joining may be performed on only one side of the outer periphery. Alternatively, joining may be performed on only two sides of the outer periphery. Alternatively, joining may be performed on the four sides of the outer periphery. All four sides can be made even.

[0356] In addition, in FIGS. 17(A) and 17(B), the positive electrode 511 is covered with the separator 503. However, one embodiment of the present invention is not limited to this case. 1 may not be covered with the separator 503. For example, instead of the positive electrode 511, The pole 515 may be covered by a separator 503 .

[0357] [Prepare the negative electrode] Next, a negative electrode 515 is prepared (see FIG. 17(C)). In FIG. 17(C), a slit is formed. The negative electrode current collector 505 has a meandering shape formed by forming a negative electrode active material layer 506 on both sides. Here is an example:

[0358] By forming a slit in the negative electrode current collector 505, when the secondary battery 102 is bent, It is possible to prevent the positions of the ends of multiple current collectors from shifting. This allows the tension applied to the current collector to be reduced.

[0359] [Put the positive and negative electrodes together and connect the leads] Next, the positive electrode 511 and the negative electrode 515 are stacked (see FIG. 18(A)). In this embodiment, an example is shown in which two positive electrodes 511 and two negative electrodes 515 are used.

[0360] Next, the positive electrode tabs of the plurality of positive electrode current collectors 501 and the positive electrode lead 521 having the sealing layer 520 are The two parts are electrically connected by applying pressure and irradiating them with ultrasonic waves (ultrasonic welding).

[0361] In addition, the leads may crack or break due to stress caused by external force applied after the capacitor is manufactured. Disconnection is likely to occur.

[0362] Therefore, when ultrasonically welding the positive electrode lead 521, it is sandwiched by a bonding die having a protrusion. This allows the positive electrode tab to have a connection region and a curved portion (FIG. 18(B)).

[0363] By providing this curved portion, it is possible to prevent the secondary battery 102 from being subjected to external force after fabrication. Therefore, the reliability of the secondary battery 102 can be improved. do.

[0364] Furthermore, the positive electrode tab is not limited to being curved, and the material of the positive electrode current collector may be stainless steel. The thickness of the positive electrode current collector is set to 10 μm or less, which makes it easy to fabricate a secondary battery. The structure may be such that stress caused by application of external force after manufacturing can be easily alleviated.

[0365] Of course, it goes without saying that a combination of these may be used to alleviate stress concentration on the positive electrode tab. None.

[0366] Similarly to the positive electrode current collector 501, the negative electrode tab of the negative electrode current collector 505 and the sealing layer 520 are The negative electrode lead 525 is electrically connected by ultrasonic welding.

[0367] [Prepare an outer casing to cover the positive and negative electrodes] The film used for the exterior is folded and one of the overlapping sides is bonded by thermocompression. 8(B), the portion where one side of the exterior body 507 is joined by thermocompression is shown as a joint portion 507a. Positive electrode 511 and negative electrode 515 are covered with this exterior body 507 .

[0368] [Inject the electrolyte] Next, the sealing layer 520 of the positive electrode lead 521 and the sealing layer 525 of the negative electrode lead 525 are The side of the exterior body 507 that overlaps with 520 is thermocompressed in the same manner as above (FIG. 19(A)). After that, the electrolyte 507 is poured from the unsealed side 507b of the package 507 shown in FIG. 04 is placed in the area covered by the exterior body 507.

[0369] Then, the remaining side of the exterior body 507 is sealed while vacuuming, heating and pressurizing. A secondary battery 102 is obtained (FIG. 19(B)). The injection of the electrolyte and the sealing are performed by a globe box. The vacuum sealer and the injection device are used in an oxygen-free environment. It is recommended to use a sealer or similar. It is also recommended to clamp the seal between two heatable bars of the sealer. Heating and pressure can be applied by the following method. For example, the vacuum level is 60kJ. The temperature can be adjusted to 190°C, the pressure to 0.1 MPa, and the time can be set to 3 seconds. The sealing may be performed with the exterior body 507 pressed down from above. Air bubbles that may have been mixed in when the liquid was poured can be removed from between the positive and negative electrodes.

[0370] [Modification] As a modification of the secondary battery 102, a secondary battery 102 is shown in FIG. 20(A). The secondary battery 102 shown in FIG. 15 has a positive electrode lead 521 and a negative electrode lead 15. Specifically, the secondary battery 102 of FIG. The negative electrode lead 525 is disposed on the same side of the exterior body 507, but the negative electrode lead 525 is disposed on the same side of the exterior body 507. In 02, the positive electrode lead 521 and the negative electrode lead 525 are attached to different sides of the outer casing 507. In this way, the secondary battery according to one embodiment of the present invention allows the leads to be freely arranged. Therefore, the degree of freedom in designing a product using the secondary battery of one embodiment of the present invention is high. In addition, the productivity of a product using the secondary battery of one embodiment of the present invention can be improved. can be increased.

[0371] FIG. 20B is a diagram illustrating the manufacturing process of the secondary battery 102 of FIG. 20B, the manufacturing method of the secondary battery 102 in FIG. 15 can be referred to. The electrolyte 504 is omitted.

[0372] In addition, in order to make the surface of the film used for the exterior body 507 uneven in advance, press processing, e.g. For example, embossing may be performed. By providing the film surface with irregularities, it is possible to improve the properties of the film as a secondary battery. Flexibility and stress relief are improved. Embossing improves the film surface (or The recessed or protruding portions formed on the back surface of the film are the volume of the space that makes the film a part of the wall of the sealing structure. This closed space is formed by the concave or convex parts of the film forming a bellows structure. It can be said that it is formed as a bellows structure. Any method that can form a relief on a part of a film may be used, regardless of the method.

[0373] Note that one embodiment of the present invention is not limited to these. Since various inventive aspects have been described, it is understood that one aspect of the present invention is not limited to any particular aspect. For example, as one embodiment of the present invention, an example in which the present invention is applied to a lithium ion secondary battery is shown below. One aspect of the present invention is to provide a battery that can be used in a variety of secondary batteries, lead-acid batteries, lithium batteries, etc. nickel-ion polymer secondary battery, nickel-metal hydride battery, nickel-cadmium battery, Nickel-iron batteries, nickel-zinc batteries, silver-oxide-zinc batteries, solid-state batteries, air batteries, The present invention may be applied to secondary batteries, capacitors, lithium ion capacitors, etc. The above embodiment does not necessarily have to be applied to lithium ion secondary batteries.
