Description

  The present invention relates to a laminated battery in which an electrode body is covered with a laminated film outer package.

  Conventionally, a laminate type battery in which an electrode body is covered with a laminate film outer package is known. Such a laminated battery has a configuration in which the outer peripheral side of the laminate film exterior body is sealed in a state where the electrode body is covered with the laminate film exterior body. Therefore, the electrode body is disposed so as to be movable with respect to the laminate film exterior body.

  On the other hand, as disclosed in Patent Document 1, for example, a configuration is known in which a concave portion that is recessed in the thickness direction is provided in one laminate film exterior body of a pair of laminate film exterior bodies that sandwich the electrode body. By disposing the electrode body in the recess, when assembling the battery, the electrode body can be easily positioned with respect to the laminate film exterior body, and the electrode body with respect to the laminate film exterior body in the state of the battery Can be prevented from moving.

  Patent Document 1 also discloses a configuration in which a double-sided pressure-sensitive adhesive tape is disposed between a laminate film exterior body and an electrode body, and the electrode body is fixed to the laminate film exterior body. With the configuration disclosed in Patent Document 1, since the laminate film exterior body is fixed to the electrode body, it is possible to prevent the battery from being swollen due to gas generation at a high temperature.

JP 2003-151512 A

  By the way, when the recessed part as disclosed in the above-mentioned Patent Document 1 is not formed in the laminate film exterior body, it becomes difficult to position the electrode body with respect to the laminate film exterior body, and the assembly workability of the battery is lowered. To do.

  For example, in the case of a thin laminated battery using a thin electrode body, the electrode body is accommodated in the laminate film outer package according to the configuration disclosed in Patent Document 1 according to the thickness of the electrode body. It is difficult to form a recess for the purpose. That is, if the thickness of the electrode body is thin, there is a possibility that the shape does not remain as a recess even if the laminate film exterior body is deformed so as to form a recess according to the thickness. Therefore, in the case of such a thin laminated battery, it is difficult to position the electrode body with respect to the laminated film outer package, and the assembling workability of the battery is greatly reduced.

  Therefore, there is a need for a battery configuration that does not affect the battery assembly workability even when the laminate film exterior body does not have a recess as disclosed in Patent Document 1 described above.

  Furthermore, as disclosed in Patent Document 1 described above, when a double-sided pressure-sensitive adhesive tape is disposed between the laminate film outer package and the electrode body, the thickness of the entire battery increases by the amount of the double-sided pressure-sensitive adhesive tape. In addition, when the electrode body is thin, the rigidity of the electrode body becomes extremely low and it is difficult to grip the electrode body, so that it is difficult to fix the electrode body and the laminate film exterior body with a double-sided adhesive tape. .

  An object of the present invention is to realize a compact and easy assembly operation in a laminated battery in which an electrode body is covered with a laminated film exterior body.

  A laminated battery according to an embodiment of the present invention includes an electrode body, a laminate film exterior body that covers the electrode body, and an adhesive tape for fixing the electrode body to the laminate film exterior body. The adhesive tape is attached so as to straddle the electrode body and the laminate film exterior body when the laminate film exterior body is viewed in plan (first configuration).

  The electrode body can be fixed to the laminate film exterior body by fixing the electrode body and the laminate film exterior body with an adhesive tape. Thereby, even when the recessed part for accommodating an electrode body is not formed in the laminate film exterior body, the assembly workability | operativity of a battery can be improved.

  Moreover, since the adhesive tape is attached so as to straddle the electrode body and the laminate film exterior body when the laminate film exterior body is seen in a plane, the electrode body and laminate film exterior are provided like a double-sided adhesive tape. Both can be fixed without being arranged between the body. Thereby, it is possible to prevent the thickness of the entire battery from increasing.

  In the first configuration, the adhesive tape has an adhesive layer only on one side (second configuration). Thereby, since an adhesive tape is not pinched between an electrode body and a laminate film exterior body, it can prevent more reliably that the thickness of a battery increases with this adhesive tape.

  In the first or second configuration, a connection terminal provided to protrude outward from the electrode body is further provided. The adhesive tape fixes a portion of the electrode body where the connection terminal is provided and a portion located on a side opposite to the protruding direction of the connection terminal to the laminate film exterior body. (Third configuration).

  Thereby, an electrode body can be more reliably fixed with respect to a laminate film exterior body. Since the portion of the electrode body where the connection terminal is provided is heavier than the other portion of the electrode body, it is easy to move relative to the laminate film exterior body. Therefore, by fixing the portion to the laminate film exterior body with an adhesive tape, and fixing the portion located on the opposite side to the protruding direction of the connection terminal relative to the portion to the laminate film exterior body with an adhesive tape, The movement of the electrode body relative to the laminate film exterior body can be prevented more reliably.

  In any one of the first to third configurations, the electrode body is configured by laminating a sheet-like positive electrode, a negative electrode, and a separator, respectively (fourth configuration).

  Thus, when an electrode body is constituted by a laminate in which sheet-like positive electrodes, negative electrodes, and separators are laminated, conventionally, a tape or the like is applied to the electrode body so as to sandwich the electrode body in the thickness direction. The positive electrode, the negative electrode, and the separator are fixed in the thickness direction by pasting in a letter shape. However, when the thickness of the electrode body is reduced, the work of fixing in the thickness direction with a tape or the like becomes difficult.

  On the other hand, the positive electrode, the negative electrode, and the separator of the electrode body can be easily fixed with the adhesive tape by fixing the electrode body to the laminate film outer package with the adhesive tape as in the first to third configurations described above. it can.

  Therefore, by applying the first to third configurations in the above-described configuration, it is possible to improve the assembling workability of the laminated battery having the electrode body composed of the laminated body.

  In any one of the first to fourth configurations, the laminate film exterior body has a flat sheet shape in which a recess for housing the electrode body is not formed (fifth configuration). .

  As described above, in the case where the concave portion for housing the electrode body is not formed in the laminate film exterior body, it is difficult to position the electrode body with respect to the laminate film exterior body. In addition, the electrode body may move with respect to the laminate film outer package.

  On the other hand, in the configuration as described above, the electrode body can be easily fixed to the laminate film exterior body by applying the first configuration described above. Therefore, a laminated battery can be easily manufactured.

  A method for manufacturing a laminated battery according to an embodiment of the present invention includes a step of forming an electrode body by laminating a sheet-like positive electrode, a negative electrode, and a separator, and the electrode body is disposed on a laminate film exterior body. A step of attaching an adhesive tape so as to straddle the electrode body and the laminate film exterior body when the laminate film exterior body is viewed in a plane, and between the laminate film exterior body and the laminate film exterior body And a step of welding the laminate film outer package disposed so as to sandwich the electrode body on the outer peripheral side thereof (first method).

  Thereby, an electrode body can be easily fixed with respect to a laminate film exterior body. That is, by sticking the adhesive tape across the electrode body and the laminate film exterior body, it is possible to prevent the electrode body from being deformed while fixing the electrode body to the laminate film exterior body. Therefore, the assembly workability of the laminated battery can be improved.

  According to the laminated battery according to one embodiment of the present invention, the adhesive tape is applied so as to straddle the electrode body and the laminate film exterior body when the laminate film exterior body is seen in a plan view. Thereby, a laminate-type battery which is compact and has good assembly workability can be obtained.

FIG. 3 is a diagram schematically showing a state in which the electrode body is fixed to the laminate film exterior body with an adhesive tape. FIG. 4 is a diagram schematically showing a state in which the outer peripheral portion of the laminate film outer package is welded.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The same or corresponding parts in the drawings are denoted by the same reference numerals and description thereof will not be repeated.

(overall structure)
FIG. 1 is a view showing an appearance of a laminated battery 1 according to an embodiment of the present invention. FIG. 2 is a cross-sectional view showing a schematic configuration of the laminated battery 1. This laminated battery 1 is a secondary battery in which an electrode body 10 that functions as a power generator is covered with a laminate film outer package 20. The laminated battery 1 is used as a battery of a thin wearable device, for example.

  As shown in FIGS. 1 and 2, the laminated battery 1 includes an electrode body 10 and a laminate film exterior body 20 that covers the electrode body 10. The laminated battery 1 includes a positive electrode connection terminal 41 and a negative electrode connection terminal 42 (connection terminal) connected to the positive electrode 11 and the negative electrode 12 of the electrode body 10, respectively. Note that a non-aqueous electrolyte is also enclosed in the laminated battery 1.

  The laminate film outer package 20 is made of a material in which one surface side of an aluminum metal foil is covered with nylon and the other surface side is covered with polypropylene. That is, the laminate film outer package 20 is made of a material obtained by laminating aluminum with nylon and polypropylene. Thereby, the laminate film exterior body 20 is mutually adhere | attached by applying a pressure, heating in the state which laminated | stacked laminate film exterior body 20 mutually. The metal foil is not limited to aluminum but may be formed of other metal materials such as stainless steel. The thickness of the laminate film outer package 20 is, for example, about 85 μm.

  The laminate film exterior body 20 has a flat sheet shape in which no recess for accommodating the electrode body 10 is formed. That is, in the conventional configuration, in order to position the electrode body 10 with respect to the laminate film exterior body 20, the laminate film exterior body 20 is formed with a recess recessed in the thickness direction. However, in this embodiment, such a recess is not formed in the laminate film exterior body 20.

  Moreover, the laminate film exterior body 20 is formed in a substantially rectangular shape. By welding the outer peripheral sides of the laminate film exterior body 20 with the electrode body 10 sandwiched between the pair of laminate film exterior bodies 20, the bulging portion 1a and the seal portion 1b as shown in FIGS. Is formed. That is, the swelled portion 1a is formed by covering the electrode body 10 with the laminate film exterior body 20, and the swelled portion 1a is surrounded by adhering the laminate film exterior body 20 around the swelled portion 1a. A seal portion 1b is formed.

  The electrode body 10 is a laminated body formed by superimposing a positive electrode 11 and a negative electrode 12 each formed in a sheet shape so that a sheet-like separator 13 is positioned between them. In the present embodiment, the electrode body 10 is a laminated body in which the sheet-like positive electrode 11, the negative electrode 12 and the separator 13 are laminated. However, the present invention is not limited to this, and the positive electrode 11, the negative electrode 12 and the separator 13 are laminated. It may be a wound body formed into a flat shape by being crushed after being wound in a state.

  The electrode body 10 of the present embodiment is a thin electrode body in which a conventional concave portion cannot be formed in the laminate film exterior body 20. That is, conventionally, in order to be able to position the electrode body with respect to the laminate film exterior body, a recess is formed in the laminate film exterior body in accordance with the thickness of the electrode body (for example, the thickness of the electrode body is 2.8 mm). And the depth of the recess is 2.5 mm). However, when the thickness of the electrode body is thin, it is difficult to form a shallow concave portion in the laminate film exterior body accordingly. As an example of such a thin electrode body 10, as shown in FIG. 2, there are five configurations including a positive electrode 11 and a negative electrode 12. In this case, the electrode body 10 has a thickness of, for example, 0.9 mm. In addition, the thickness of the electrode body 10 of the laminated battery 1 to which the configuration of the present embodiment is applied is preferably less than 2 mm.

  In the present embodiment, as shown in FIG. 2, the electrode body 10 is a laminated body in which the positive electrode 11 and the negative electrode 12 are laminated in a total of five layers. There may be 6 or more laminated bodies. In the laminated battery to which the configuration of the present embodiment is applied, it is preferable that the electrode body 10 has such a thickness that a concave portion cannot be formed in the laminate film exterior body 20, but this is not a limitation, and the electrode body 10 thicker than that. May be used.

In the positive electrode 11, a positive electrode active material layer containing a positive electrode active material is provided on both surfaces or one surface of a positive electrode current collector made of a metal foil such as aluminum. Specifically, the positive electrode 11 is formed by applying a positive electrode mixture containing a positive electrode active material that is a lithium-containing oxide capable of occluding and releasing lithium ions, a conductive additive, and a binder onto a positive electrode current collector made of aluminum foil or the like. And then dried. As the lithium-containing oxide as the positive electrode active material, for example, a lithium composite oxide such as lithium cobalt oxide such as LiCoO ₂ , lithium manganese oxide such as LiMn ₂ O ₄ , lithium nickel oxide such as LiNiO ₂ is used. Is preferred. Note that only one type of material may be used as the positive electrode active material, or two or more types of materials may be used. Further, the positive electrode active material is not limited to the above-described materials.

  In the negative electrode 12, negative electrode active material layers containing a negative electrode active material are provided on both sides of a negative electrode current collector made of a metal foil such as copper. Specifically, the negative electrode 12 is formed by applying and drying a negative electrode mixture containing a negative electrode active material capable of occluding and releasing lithium ions, a conductive additive and a binder on a negative electrode current collector made of copper foil or the like. It is formed. As the negative electrode active material, for example, it is preferable to use a carbon material (such as graphite, pyrolytic carbon, coke, or glassy carbon) that can occlude and release lithium ions. The negative electrode active material is not limited to the above-described materials.

  The positive electrode 11 of the electrode body 10 is connected to a positive electrode connection terminal 41 in a current collector exposed region (not shown) where a positive electrode active material layer is not formed and the positive electrode current collector is exposed. On the other hand, the negative electrode 12 has a negative electrode connection terminal 42 connected to a current collector exposed region (not shown) where the negative electrode active material layer is not formed and the negative electrode current collector is exposed. As shown in FIG. 1, the positive electrode connection terminal 41 and the negative electrode connection terminal 42 are partially exposed to the outside of the laminate film exterior body 20. Thereby, an impedance can be made small compared with the structure which draws out a connection terminal outside through other connection components.

(Adhesive tape)
As shown in FIG. 3, the electrode body 10 configured by laminating a plurality of sheet-like positive electrodes 11 and negative electrodes 12 is fixed to the laminate film exterior body 20 with an adhesive tape 30. That is, the electrode body 10 is the side of the electrode body 10 where the positive electrode connection terminal 41 and the negative electrode connection terminal 42 are provided in the electrode body 10, and the opposite side of the electrode body 10. And the both sides of the width direction of the electrode body 10 in the center part of the longitudinal direction of the electrode body 10 are being fixed by the adhesive tape 30, respectively. Note that the hatched portion in FIG. 3 indicates the bonding location of the adhesive tape 30.

  The adhesive tape 30 is made of a resin material such as polypropylene (PP) or polyphenylene sulfide (PPS), and an adhesive layer is formed only on one side. A part of the adhesive tape 30 is bonded to the laminate film outer package 20, and the other part is bonded to the electrode body 10. That is, the adhesive tape 30 is attached to the laminate film exterior body 20 and the electrode body 10 so as to straddle the laminate film exterior body 20 in a plan view.

  With such a configuration, the electrode body 10 can be easily fixed to the laminate film exterior body 20 by the adhesive tape 30. Moreover, the positive electrode 11, the negative electrode 12, and the separator 13 of the electrode body 10 can also be fixed by the adhesive tape 30 by fixing the electrode body 10, which is a laminate, to the laminate film exterior body 20 with the adhesive tape 30 as described above. it can. That is, the adhesive tape 30 can fix the electrode body 10 to the laminate film exterior body 20 while preventing the electrode body 10 from being deformed.

  Moreover, as described above, the positive electrode connection terminal 41 and the negative electrode connection terminal 42 side of the electrode body 10 and the opposite side of the electrode body 10 are fixed to the laminate film outer package 20 by the adhesive tape 30, respectively. The electrode body 10 can be more reliably fixed to the body 20. That is, in the electrode body 10, the portion where the positive electrode connection terminal 41 and the negative electrode connection terminal 42 are provided is heavier than the other portions, and thus the portion is displaced with respect to the laminate film exterior body 20. Cheap. By fixing such a portion with respect to the laminate film exterior body 20 with the adhesive tape 30 as described above, the electrode body 10 can be more reliably prevented from moving relative to the laminate film exterior body 20.

  In the present embodiment, in the electrode body 10, the side opposite to the side where the positive electrode connection terminal 41 and the negative electrode connection terminal 42 are provided, and the central portion in the width direction of the electrode body 10, and the longitudinal direction of the electrode body 10 Both sides in the width direction of the electrode body 10 are fixed to the laminate film exterior body 20 by the adhesive tape 30 at the center portion of the laminated body. However, in the electrode body 10, the laminate film exterior body is covered with the adhesive tape 30 on the side opposite to the side where the positive electrode connection terminal 41 and the negative electrode connection terminal 42 are provided and on both sides or only one side in the width direction of the electrode body 10. You may fix to 20.

(Laminated battery manufacturing method)
Next, a method for manufacturing the laminated battery 1 having the above-described configuration will be described.

  First, the electrode body 10 is formed by superimposing the positive electrode 11, the negative electrode 12, and the separator 13 each formed in a sheet shape. A positive electrode connection terminal 41 and a negative electrode connection terminal 42 are connected to the positive electrode 11 and the negative electrode 12, respectively.

  In a state where the electrode body 10 is disposed on the laminate film exterior body 20, an adhesive tape 30 is applied so as to straddle the electrode body 20 and the laminate film exterior body 20, as shown in FIG. At this time, as shown in FIG. 3, the portion of the electrode body 10 on the positive electrode connection terminal 41 and negative electrode connection terminal 42 side, the opposite side and the center portion in the width direction of the electrode body 10, and the longitudinal direction of the electrode body 10 The both sides of the electrode body 10 in the center portion in the width direction are bonded and fixed to the laminate film exterior body 20 with the adhesive tape 30.

  Next, the outer peripheral side is welded in a state where another laminate film exterior body 20 is superimposed on the laminate film exterior body 20 to which the electrode body 10 is fixed by the adhesive tape 30. Specifically, first, in a state in which the two laminate film exterior bodies 20 are overlapped, a portion corresponding to three sides other than one side in the longitudinal direction of the electrode body 10 is welded, and the laminate film exterior body is started from the unwelded portion. A non-aqueous electrolyte is injected between the 20 members. Then, the laminated battery 1 as shown in FIG. 1 is obtained by welding the part which is not welded by the laminate film exterior bodies 20 mutually.

  Here, when the laminate film outer bodies 20 are welded to each other, the welding is performed at a position that does not overlap the adhesive tape 30. In FIG. 4, the welded portion of the laminate film outer package 20 is denoted by reference numeral 21. This is because if the adhesive tape 30 and the welded portion overlap, the sealing performance at that portion may be impaired. In addition, in the laminated film exterior body 20, since the part of the outer peripheral side rather than a welding part is an excess part, it cut | disconnects.

(Effect of embodiment)
In the present embodiment, the electrode body 10 is fixed to the laminate film exterior body 20 that covers the electrode body 10 by the adhesive tape 30. Thereby, even if the electrode body 10 is a thin electrode body in which a conventional concave portion cannot be formed in the laminate film exterior body 20, the electrode body 10 can be easily fixed to the laminate film exterior body 20. it can.

  Moreover, the adhesive tape 30 is attached to the adhesive tape 30 across the electrode body 10 and the laminate film exterior body 20 when the laminate film exterior body 20 is viewed in a plan view. Can be fixed easily. Further, by fixing the electrode body 10 and the laminate film exterior body 20 with the adhesive tape 30 as described above, the sheet-like positive electrode 11, negative electrode 12, and separator 13 constituting the electrode body 10 are fixed with the adhesive tape 30. can do. That is, it is possible to prevent the electrode body 10 from being deformed while the electrode body 10 is fixed to the laminate film exterior body 20 by the adhesive tape 30.

  Therefore, according to the configuration of the present embodiment, there is no need to form a recess in the laminate film exterior body 20 as in the conventional case. Therefore, since the manufacturing process of the laminate type battery is reduced accordingly, the manufacturing process of the laminate type battery can be simplified.

  The adhesive tape 30 has an adhesive layer only on one side. Thereby, the electrode body 10 can be easily fixed to the laminate film exterior body 20 by the adhesive tape 30. And since it is not necessary to arrange | position between adhesion objects like a double-sided tape, it can prevent that the thickness of the whole battery becomes large like the case where a double-sided tape is used.

  In the present embodiment, a portion on the positive electrode connecting member 41 and negative electrode connecting member 42 side in the electrode body 10 and a portion located on the opposite side are fixed to the laminate film exterior body 20 by the adhesive tape 30. As a result, the heavy portion of the electrode body 10 on the side of the positive electrode connecting member 41 and the negative electrode connecting member 42 can be more reliably fixed to the laminate film exterior body 20 by the adhesive tape 30. Therefore, it is possible to prevent the portions on the positive electrode connecting member 41 and the negative electrode connecting member 42 side of the electrode body 10 from moving with respect to the laminate film exterior body 20.

  In the embodiment, the positive electrode connecting member 41 and the negative electrode connecting member 42 side of the electrode body 10 are fixed to the laminate film exterior body 20 with the adhesive tape 30. However, the portion where the electrode body 10 is fixed by the adhesive tape 30 may be a portion other than the positive electrode connecting member 41 and the negative electrode connecting member 42 side in the electrode body 10. The attachment position of the adhesive tape 30 to the electrode body 10 may be one on each side of the rectangular electrode body 10 in a plan view, or may be a plurality of positions among those sides, or each corner of the electrode body 10 One part or a plurality of corners may be provided.

  In the embodiment, the positive electrode connection terminal 41 and the negative electrode connection terminal 42 are connected to the electrode body 10 one by one. However, a plurality of positive electrode connection terminals 41 and a plurality of negative electrode connection terminals 42 may be connected to the electrode body 10. Also in this case, it is preferable that the plurality of positive electrode connection terminals 41 and negative electrode connection terminals 42 in the electrode body 10 are fixed to the laminate film exterior body 20 with the adhesive tape 30.

  In the embodiment, a tape having an adhesive layer only on one side is used as the adhesive tape 30. However, a double-sided adhesive tape having adhesive layers on both sides may be used as the adhesive tape 30.
