Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same components are denoted by the same reference numerals, and the description thereof is omitted as appropriate.
Fig. 1 is a perspective view of a battery 10 according to an embodiment. Fig. 2 is an enlarged plan view of a part of the battery 10 shown in fig. 1.
The outline of the battery 10 will be described with reference to fig. 1. The battery 10 includes a laminate 100 and an external device 200. The stack 100 includes a 1 st electrode 110, a 2 nd electrode 120, and a separator 130. The laminate 100 has a 1 st surface 102a, a 2 nd surface 102b, a 1 st side surface 104a, a 2 nd side surface 104b, a 3 rd side surface 104c, a 4 th side surface 104d, and a 1 st corner 106 a. The 2 nd surface 102b is located opposite to the 1 st surface 102 a. The 1 st side surface 104a is located between the 1 st surface 102a and the 2 nd surface 102 b. A 1 st lead 112 is formed on the 1 st side surface 104 a. The 2 nd side 104b intersects the 1 st side 104 a. The 3 rd side surface 104c is located opposite to the 1 st side surface 104 a. The 4 th side surface 104d is located opposite the 2 nd side surface 104 b. The 1 st corner 106a is located between the 1 st side 104a and the 2 nd side 104 b. The package 200 is folded back from the 1 st surface 102a to the 2 nd surface 102b of the laminate 100 via the 4 th side surface 104 d. The outer fitting 200 has a 1 st part 210 and a 2 nd part 220. The 1 st part 210 and the 2 nd part 220 are bonded to the outside of the 1 st side surface 104a and the 2 nd side surface 104b of the laminate 100. Part 1 210 and part 2 220 of the outer fitting 200 have deformations 202a (1 st deformation). The deformation 202a extends from the 1 st corner 106a of the stack 100.
According to the above configuration, the storage space of the stacked body 100 formed of the external equipment 200 can be reduced. Specifically, in the above-described structure, the 1 st part 210 and the 2 nd part 220 of the outer fitting 200 have the deformation 202 a. When the 1 st part 210 and the 2 nd part 220 of the external device 200 are bonded in the region close to the 2 nd side surface 104b of the laminate 100, the 1 st part 210 and the 2 nd part 220 of the external device 200 are deformed so as to eliminate a bulge 204a (for example, fig. 5) described later, thereby forming a deformation 202 a. Thus, the presence of the deformation 202a indicates: the 1 st part 210 and the 2 nd part 220 of the package 200 are bonded to each other in a region close to the 2 nd side surface 104b of the laminate 100, that is, the accommodation space of the laminate 100 formed by the package 200 is reduced.
In the example shown in fig. 1, the 2 nd lead 122 is formed on the 3 rd side surface 104c of the laminate 100. The stack 100 has a 2 nd corner 106 b. The 2 nd corner 106b is located between the 3 rd side 104c and the 2 nd side 104 b. The 1 st part 210 and the 2 nd part 220 of the outer package 200 are bonded to the outside of the 3 rd side surface 104c of the laminate 100. Part 1 210 and part 2 220 of the outer fitting 200 have deformations 202b (2 nd deformation). The deformation 202b extends from the 2 nd corner 106b of the stack 100.
In another example, both the 1 st lead 112 and the 2 nd lead 122 may be formed on a common surface of the laminate 100, for example, the 1 st side surface 104a or the 3 rd side surface 104 c. When both the 1 st lead 112 and the 2 nd lead 122 are formed on the 1 st side surface 104a, the 1 st portion 210 and the 2 nd portion 220 are bonded to the outside of the 1 st side surface 104a and the 2 nd side surface 104b of the laminate 100, and have a deformation 202 a.
The laminated body 100 will be described in detail with reference to fig. 1.
The stack 100 includes a 1 st electrode 110, a 2 nd electrode 120, and a separator 130. The 1 st electrode 110 and the 2 nd electrode 120 have different polarities from each other, and may be a positive electrode and a negative electrode, or may be a negative electrode and a positive electrode, respectively. The 1 st electrode 110, the 2 nd electrode 120, and the separator 130 are laminated from the 1 st face 102a to the 2 nd face 102b such that the 1 st electrode 110 and the 2 nd electrode 120 are separated by the separator 130. The stack 100 may also include a plurality of 1 st electrodes 110 and a plurality of 2 nd electrodes 120. In this case, the adjacent 1 st and 2 nd electrodes 110 and 120 are separated by a separator 130.
The laminate 100 has a substantially rectangular parallelepiped shape. The laminate 100 has a thickness between the 1 st surface 102a and the 2 nd surface 102b, a length between the 1 st side surface 104a and the 3 rd side surface 104c, and a width between the 2 nd side surface 104b and the 4 th side surface 104 d.
In the example shown in fig. 1, the length of the stacked body 100 (between the 1 st side surface 104a and the 3 rd side surface 104 c) is larger than the width of the stacked body 100 (between the 2 nd side surface 104b and the 4 th side surface 104 d). If the ratio of the length to the width is large, the laminate 100 can be easily placed so that the 2 nd side surface 104b or the 4 th side surface 104d of the laminate 100 faces downward. The ratio can be, for example, more than 2.0 in order to stably place the laminate 100 with the 2 nd side surface 104b or the 4 th side surface 104d of the laminate 100 directed downward.
The 1 st lead 112 protrudes from the 1 st side surface 104a of the laminate 100. The 1 st lead 112 is electrically connected to the 1 st electrode 110 of the stack 100.
The 2 nd lead 122 protrudes from the 2 nd side surface 104b of the laminate 100. The 2 nd lead 122 is electrically connected to the 2 nd electrode 120 of the stack 100.
As described later, this embodiment is particularly significant when the thickness between the 1 st surface 102a and the 2 nd surface 102b is large. The laminate 100 may have a thickness of, for example, 5.0mm or more, 7.5mm or more, or 10.0mm or more between the 1 st surface 102a and the 2 nd surface 102 b.
The package 200 will be described in detail with reference to fig. 1.
The outer package 200 defines a space for housing the stacked body 100. In this space of the package 200, the laminate 100 and the electrolyte are housed. In this way, the outer package 200 seals the laminate 100.
In the example shown in fig. 1, the housing space of the stack 100 formed by the external device 200 is not formed by molding (emboss). The exterior part 200 is bent along the corner between the 1 st surface 102a and the 4 th side surface 104d and the corner between the 2 nd surface 102b and the 4 th side surface 104d of the laminate 100 so as to wrap the laminate 100. Further, the package 200 includes a portion extending along the 4 th side surface 104d of the laminate 100. In general, molding for forming a deep depression requires a complicated technique. Therefore, as the thickness of the laminate 100 increases, a more complicated technique is required to form the housing space of the laminate 100 formed of the external device 200 by pressing. In contrast, in the present embodiment, the use of embossing is not required. Therefore, even if the thickness of the laminate 100 is large, the housing space of the laminate 100 formed of the external device 200 can be easily formed.
The deformation 202a of the package 200 will be described in detail with reference to fig. 1 and 2.
The deformation 202a extends from the 1 st corner 106a of the laminate 100 to the edge of the outer package 200 (the edge along the 1 st side 104a of the laminate 100). In the cross section of the outer fitting 200, the 1 st and 2 nd parts 210, 220 of the outer fitting 200 in the deformation 202a are curved to be convex. The deformation 202b also has the same shape as the deformation 202 a.
Fig. 3 to 7 are diagrams for explaining an example of the method for manufacturing the battery 10 shown in fig. 1 and 2.
First, as shown in fig. 3, the package 200 is folded back from the 1 st surface 102a (fig. 1) to the 2 nd surface 102b (fig. 1) of the laminate 100 via the 4 th side surface 104 d. In this way, the 1 st part 210 and the 2 nd part 220 in the package 200 are overlapped outside the 1 st side surface 104a, the 2 nd side surface 104b, and the 3 rd side surface 104c of the laminate 100.
Next, as shown in fig. 4, the 1 st part 210 and the 2 nd part 220 of the external fitting 200 are attached to the 1 st region 232. The 1 st region 232 is along the 1 st side 104a of the stack 100.
The ridge 204a (1 st ridge) is formed on the 1 st part 210 by the attachment of the 1 st part 210 and the 2 nd part 220 in the 1 st region 232. The protuberance 204a extends from the 1 st corner 106a to the 1 st area 232. The width of the ridge 204a is narrower the further away from the 1 st corner 106 a. The ridge 204a results from the deformation in the outer fitting 200 caused by narrowing the spacing between the 1 st part 210 and the 2 nd part 220 from the 1 st corner 106a of the laminate 100 to the 1 st region 232 of the outer fitting 200.
By the adhesion of the 1 st portion 210 and the 2 nd portion 220 in the 1 st region 232, a ridge is formed on the 2 nd portion 220 on the opposite side of the ridge 204a as in the ridge 204a of the 1 st portion 210.
As shown in fig. 4, the 1 st portion 210 and the 2 nd portion 220 of the outer fitting 200 are attached in the 3 rd region 236. Zone 3 236 is along side 3 of the stack 100, 104 c. Thus, the ridge 204b (2 nd ridge) is formed in the 1 st part 210, as is the ridge 204a of the 1 st part 210. The protuberance 204b extends from the 2 nd corner 106b to the 3 rd region 236. The width of the ridge 204b is narrower the further away from the 2 nd corner 106 b.
By the adhesion of the 1 st part 210 and the 2 nd part 220 in the 3 rd region 236, a ridge is formed on the 2 nd part 220 on the opposite side of the ridge 204b, similarly to the ridge 204b of the 1 st part 210.
Next, as shown in fig. 5, the package 200 is folded along the 2 nd side surface 104b of the laminate 100. The single-dot chain line in fig. 5 indicates a line along the bending line of the outer fitting 200. By bending the external device 200, the ridges 204a and 204b can be brought closer to the stacked body 100. The reason for bending the outer package 200 will be described later.
Next, as shown in fig. 6, the 1 st part 210 and the 2 nd part 220 of the external device 200 are attached to the 1 st part region 234a and the 2 nd part region 234 b. The 1 st partial region 234a is located on the opposite side of the 1 st corner 106a with respect to the 2 nd side surface 104b of the stack 100. The 2 nd partial region 234b is located on the opposite side of the 2 nd corner 106b with respect to the 2 nd side surface 104b of the stack 100. The reason for bonding the 1 st part 210 and the 2 nd part 220 to the 1 st part 234a and the 2 nd part 234b will be described later.
Next, as shown in fig. 7, the 1 st part 210 and the 2 nd part 220 of the outer package 200 are attached to each other in the 2 nd region 234. The 2 nd region 234 is along the 2 nd side 104b of the stack 100. In the step shown in fig. 7, the pressure in the storage space of the laminate 100 formed of the external package 200 is set lower than the atmospheric pressure, and the 1 st part 210 and the 2 nd part 220 are bonded to each other while reducing the pressure to a vacuum, for example. The 2 nd region 234 may or may not overlap the 1 st and 2 nd subregion 234a, 234 b.
Next, the outer portion of the 2 nd region 234 in the outer fitting 200 is removed.
Thus, the battery 10 is manufactured.
In the method shown in fig. 3 to 7, the bonding of the 1 st part 210 and the 2 nd part 220 in the 1 st region 232, the 2 nd region 234, and the 3 rd region 236 can be performed by welding the 1 st part 210 and the 2 nd part 220, for example.
According to the methods shown in fig. 3 to 7, the stacked body 100 can be sealed with high reliability. Specifically, in this method, as shown in fig. 6, the 1 st part 210 and the 2 nd part 220 of the outer package 200 are attached to each other in the 1 st part region 234 a. This prevents the bulge 204a from spreading to the 2 nd region 234 at the time of decompression in fig. 7. In other words, the contact between the 1 st portion 210 and the 2 nd portion 220 in the 1 st partial region 234a functions as a stopper for restricting the expansion of the bulge 204 a. If the ridge 204a extends to the 2 nd region 234, the ridge 204a located in the 2 nd region 234 is pressed by the adhesion of the 1 st part 210 and the 2 nd part 220 in the 2 nd region 234, and thus wrinkles (for example, wrinkles 206 shown in fig. 8 described later) are formed on the surface of the external device 200. Such wrinkles form a leak path from the storage space of the laminate 100 formed by the outer package 200 to a space outside the outer package 200. In contrast, in the examples shown in fig. 6 and 7, such wrinkles can be suppressed. Therefore, the laminate 100 can be sealed with high reliability.
According to the method shown in fig. 3 to 7, deformations 202a (deformations 202b) are formed in the 1 st part 210 and the 2 nd part 220 of the outer fitting 200. Specifically, in this method, ridge 204a does not extend to region 2 234, as described above. Nevertheless, if the 1 st portion 210 and the 2 nd portion 220 are attached in the 2 nd region 234 such that the ridge 204a is planarized, the deformation 202a is formed to eliminate the ridge 204 a. The deformation 202a itself cannot form a leakage path leading from the housing space of the stacked body 100 formed of the package 200 to the space outside the package 200. Therefore, the laminate 100 can be sealed with high reliability.
According to the method shown in fig. 3 to 7, the storage space of the stacked body 100 formed of the external equipment 200 can be reduced. Specifically, in this method, as shown in fig. 5, the package 200 is bent along the 2 nd side surface 104b of the laminate 100 so that the ridge 204a and the ridge 204b approach the laminate 100. In order to suppress wrinkles in the 2 nd region 234, it is necessary that the ridge 204a and the ridge 204b do not overlap with the 2 nd region 234, the 1 st partial region 234a, and the 2 nd partial region 234 b. Therefore, the closer the ridge 204a and the ridge 204b are to the 2 nd side surface 104b of the laminate 100, the closer the 2 nd region 234 is to the 2 nd side surface 104b of the laminate 100. Therefore, the storage space of the stacked body 100 formed of the external equipment 200 can be reduced.
Other examples of methods may not include the steps shown in fig. 5. In this example, after the step shown in fig. 4 is performed, the step shown in fig. 6 is performed without going through the step shown in fig. 5. In this example, wrinkles in the 2 nd region 234 can also be suppressed by making the ridge 204a and the ridge 204b not overlap with the 1 st partial region 234a and the 2 nd partial region 234b, respectively.
Fig. 8 is a view showing a modification of fig. 2. The battery 10 according to the modification is the same as the battery 10 according to the embodiment, except for the following points.
In the example shown in fig. 8, the battery 10 is manufactured without going through the process shown in fig. 6. In the example shown in figure 8, the outer package 200 comprises a pleat 206. As described with reference to fig. 3 to 7, the wrinkle 206 is formed by bonding the 1 st part 210 and the 2 nd part 220 to the 2 nd region 234 in a state where the ridge 204a extends to the 2 nd region 234.
In the example shown in fig. 8, a deformation 202a is also formed. Even if the 1 st part 210 and the 2 nd part 220 are not bonded to the 1 st part region 234a shown in fig. 6, the 1 st part 210 and the 2 nd part 220 of the package 200 are bonded to a region close to the 2 nd side surface 104b of the laminate 100, and the distortion 202a is formed so as to eliminate a part of the bulge 204 a.
In the example shown in fig. 8, the storage space of the stacked body 100 formed of the external package 200 can be reduced.
While the embodiments of the present invention have been described above with reference to the drawings, these are illustrative of the present invention, and various configurations other than the above-described configurations can be adopted.
