Description

Technical Field

[0001] [Cross-references to related applications] This application claims priority to Korean Patent Application No. 10-2023-0089139, filed in Korea on July 10, 2023, the disclosure of which is incorporated herein by reference. [Technical Field] This disclosure relates to an electronic device, and more specifically, to an electronic device capable of separating a housed secondary battery without damage. Background Technology

[0003] Secondary batteries are highly adaptable to various product groups and possess high energy density electrical characteristics. Such secondary batteries are used not only in portable electronic devices but also in electric vehicles powered by these batteries, hybrid electric vehicles, and energy storage devices. Secondary batteries are attracting attention as a new energy source for improving environmental protection and energy efficiency because they not only have the major advantage of significantly reducing the use of fossil fuels but also produce no byproducts from energy use. Secondary battery packs used in electric vehicles, etc., have a structure that connects multiple secondary battery modules, including multiple secondary batteries, to achieve high power output.

[0004] Recently, research has been actively conducted to protect the environment and recycle resources, such as reducing carbon dioxide emissions by recycling or reusing secondary batteries that have already been used in electronic devices and are nearing the end of their lifespan. The burgeoning secondary battery recycling or reuse industry can reduce dependence on countries that possess secondary battery resources and has a positive impact on the virtuous cycle of the secondary battery supply chain.

[0005] However, for the recycling or reuse of secondary batteries, a technique is needed to separate the secondary battery from the electronic device without damage. When a structure is inserted into the gap between the electronic device and one side of the secondary battery to separate them and force is applied, the force is concentrated on one side or the other side of the secondary battery, causing damage, such as bending or warping. This makes it difficult to recycle or reuse the secondary battery. Therefore, there is a need to develop a technology to solve the above problems. Summary of the Invention

[0006] Technical issues This disclosure is designed to solve the above-mentioned problems, and therefore relates to providing an electronic device in which a secondary battery housed therein can be separated without damage for reuse.

[0007] Technical solution As an embodiment of this disclosure, this disclosure provides an electronic device, including: a main body portion having a receiving portion having a recessed shape; a secondary battery being received in the receiving portion; and an insertion unit, at least a portion of which is coupled to the secondary battery and configured to separate the secondary battery from the receiving portion as the insertion unit deforms, wherein the insertion unit includes: an operating portion; and a deformable portion connected to the operating portion and configured to deform by operation of the operating portion.

[0008] In addition, the operating part can be formed to be bent at a predetermined angle relative to the deformable part at the end of the deformable part, and can extend along the thickness direction of the secondary battery on one side of the secondary battery.

[0009] In addition, one end of the operating part is operated to move away from the secondary battery, so that the other end of the operating part connected to the deformation part can apply force in the direction of compressing the deformation part.

[0010] Additionally, the deformable portion may include: a joining portion, which joins to a surface of the secondary battery; and a non-joining portion, which extends from the joining portion and does not join to the secondary battery, wherein the non-joining portion may be configured to deform by operation of the operating portion so as to allow the secondary battery to be ejected.

[0011] Alternatively, the non-jointing portion can be configured to deform into a convex shape toward the secondary battery by the operation of the operating portion, thereby allowing the secondary battery to be ejected.

[0012] In addition, the operating part can have higher rigidity than the deformable part.

[0013] In addition, the deformable part may include a material that can be elastically deformed.

[0014] In addition, the deformable part can be formed to extend from the operating part and can be provided along the length or width direction of the secondary battery.

[0015] In addition, an insertion groove can be formed on one surface of the secondary battery in one direction, and the deformed part can be inserted into the insertion groove.

[0016] Additionally, the secondary battery may include: a first electrode assembly having at least one of a first positive electrode, a first negative electrode, and a first separator formed with a first area; a second electrode assembly having at least one of a second positive electrode, a second negative electrode, and a second separator formed with a second area smaller than the first area on the first electrode assembly, thereby forming an insertion groove; and a housing for accommodating the first electrode assembly and the second electrode assembly.

[0017] Additionally, the secondary battery may include: a third electrode assembly, configured to be spaced apart from the second electrode assembly at a predetermined distance on the first electrode assembly to form an insertion groove, the third electrode assembly being stacked with a third area smaller than the first area, and having at least one of a third positive electrode, a third negative electrode, and a third separator stacked thereon.

[0018] As another embodiment of this disclosure, this disclosure provides an electronic device, including: a secondary battery; a main body portion having a receiving portion having a recessed shape to receive the secondary battery; and an insertion unit mounted on the receiving portion and configured to separate the secondary battery from the receiving portion as the insertion unit deforms, wherein the insertion unit includes: an operating portion; and a deformable portion connected to the operating portion and configured to deform according to the operation of the operating portion.

[0019] Additionally, the deformable portion may include: a fixed portion, fixed to one side of the receiving portion; and a non-fixed portion, configured to deform according to the operation of the operating portion so that the secondary battery can be ejected from the receiving portion.

[0020] Alternatively, the non-fixed part can be configured to deform into a convex shape toward the secondary battery by the operation of the operating part, thereby allowing the secondary battery to be pushed out.

[0021] In addition, the operating part can be formed to bend at a predetermined angle relative to the non-fixed part from the end of the non-fixed part, and can extend along the depth direction of the receiving part.

[0022] Beneficial effects The electronic device disclosed herein allows users to easily separate the secondary battery contained therein, and can minimize damage to the secondary battery during the separation process, thereby increasing the possibility of recycling or reusing the separated secondary battery.

[0032] In the following description, preferred embodiments of the present disclosure will be described in sufficient detail with reference to the accompanying drawings to enable those skilled in the art to readily implement the present disclosure. However, the present disclosure may be implemented in several different forms and is not limited to or construed as described below.

[0033] In order to clearly describe this disclosure, irrelevant descriptions or detailed descriptions of related known techniques that may unnecessarily obscure the essential points of this disclosure have been omitted, and throughout the specification, the same or similar reference numerals are attached to the same or similar elements when reference numerals are attached to the elements in the various figures.

[0034] Before the description, it should be understood that the terms or words used in the specification and appended claims should not be construed as limited to their general or dictionary meanings, but should be interpreted based on the principle that the inventors are allowed to appropriately define the terms for best description, and based on the meanings and concepts corresponding to the technical aspects of this disclosure.

[0035] Example 1 Reference Figure 1 As an embodiment of this disclosure, the electronic device 10 may include a main body 100, a secondary battery 300, and an insertion unit 400.

[0036] Electronic device 10 can refer to a device that is electrically powered by a secondary battery 300. For example, electronic device 10 can be a portable terminal, a laptop computer, etc., but is not limited to these.

[0037] The main body 100 may include electronic components required for an electrically driven electronic device, and a recessed receiving portion 110 may be formed in the main body 100 to receive a secondary battery 300 that serves as a power source for driving the electronic components.

[0038] The receiving portion 110 can accommodate the secondary battery 300, enabling electrical connection between the electronic components included in the main body 100 and the secondary battery 300. The secondary battery 300 can be inserted into the receiving portion 110 such that its flat surface faces the inner bottom surface of the receiving portion 110. The secondary battery 300 can be electrically connected to the electronic components included in the main body 100 by being inserted into the receiving portion 110, and can supply electrical energy.

[0039] The depth to which the receiving portion 110 is recessed into the main body portion 100 can be less than the thickness of the secondary battery 300. Since the thickness of the secondary battery 300 housed in the receiving portion 110 is greater than the depth of the receiving portion 110, one surface of the secondary battery 300 can protrude from the receiving portion 110.

[0040] Electronic device 10 may also include cover 200.

[0041] The cover 200 can cover one surface of the main body 100 so that the secondary battery 300 is not exposed to the outside of the electronic device 10, and the cover 200 can be combined with the main body 100.

[0042] The cover 200 can be formed to be recessed to a predetermined depth to accommodate the thickness of the secondary battery 300 protruding from the receiving portion 110.

[0043] The secondary battery 300 may include a first electrode assembly (not shown), a second electrode assembly (not shown), and a housing (not shown).

[0044] The first electrode assembly is formed with a first area and may be formed having at least one of a first positive electrode, a first negative electrode, and a first diaphragm stacked on top of each other.

[0045] For example, the first electrode assembly may be, but is not limited to, a stacked electrode assembly formed by stacking a first positive electrode and a first negative electrode and stacking a diaphragm between the first positive electrode and the first negative electrode, a stacked folded electrode assembly that alternately stacks the first positive electrode and the first negative electrode by using a rectangular diaphragm that has a longer length in the horizontal direction than in the vertical direction to wind the electrode unit, and a wound electrode assembly that winds the first negative electrode, the first positive electrode, and the diaphragm inserted between the first negative electrode and the first positive electrode in one direction.

[0046] The second electrode assembly is formed with a second area smaller than the first area, and can be formed as having at least one of a second positive electrode, a second negative electrode, and a second diaphragm stacked on top of each other.

[0047] For example, the second electrode assembly may be, but is not limited to, a stacked electrode assembly formed by stacking a second positive electrode and a second negative electrode and stacking a diaphragm between the second positive electrode and the second negative electrode, a stacked folded electrode assembly that alternately stacks the second positive electrode and the second negative electrode by using a rectangular diaphragm that has a longer length in the horizontal direction than in the vertical direction to wind the electrode unit, and a wound electrode assembly that winds the second negative electrode, the second positive electrode and the diaphragm inserted between the second negative electrode and the second positive electrode in one direction.

[0048] Since the second electrode assembly is formed with a second area smaller than the first area and is configured to be stacked on the first electrode assembly, a step can be formed between the first electrode assembly and the second electrode assembly.

[0049] For example, the shape of the second electrode assembly is not limited to, but can be formed into, a rectangular shape, a curved shape, a shape with a groove recessed from one side, etc., and preferably can be formed into a rectangle for simple manufacturing process.

[0050] The secondary battery 300 may also include a third electrode assembly.

[0051] The third electrode assembly is formed with a third area and can be formed as having at least one of a third positive electrode, a third negative electrode, and a third diaphragm stacked on top of each other.

[0052] For example, the third electrode assembly may be, but is not limited to, a stacked electrode assembly formed by stacking a third positive electrode and a third negative electrode and stacking a diaphragm between the third positive electrode and the third negative electrode, a stacked folded electrode assembly that alternately stacks the third positive electrode and the third negative electrode by using a rectangular diaphragm that has a longer length in the horizontal direction than in the vertical direction to wind the electrode unit, and a wound electrode assembly that winds the third negative electrode, the third positive electrode, and the diaphragm inserted between the third negative electrode and the third positive electrode in one direction.

[0053] Since the third electrode assembly is formed with a third area smaller than the first area and is configured to be stacked on the first electrode assembly, a step can be formed between the first electrode assembly and the third electrode assembly.

[0054] For example, the shape of the third electrode assembly is not limited to, but can be formed into, a rectangular shape, a curved shape, a shape with a groove recessed from one side, etc., and preferably can be formed into a rectangle for simple manufacturing process.

[0055] The third electrode assembly can be positioned on the first electrode assembly and spaced apart from the second electrode assembly by a predetermined distance. Between the third and second electrode assemblies, a groove with a depth equal to the thickness of the second and third electrode assemblies can be formed along the surfaces facing the third and second electrode assemblies, due to a step formed by stacking the third and second electrode assemblies on the first electrode assembly. The groove is formed such that the shape of the housing corresponds to the shape of the groove when the first, second, and third electrode assemblies are housed within the housing, and an insertion slot 310 can be formed on the outer surface of the housing.

[0056] The casing forms the outer surface of the secondary battery and can house the first electrode assembly and the second electrode assembly. Additionally, the casing can house the first electrode assembly, the second electrode assembly, and the third electrode assembly.

[0057] The housing can be formed from a flexible, soft-pack material that includes a metal layer and an insulating layer.

[0058] The housing can be formed in a shape that corresponds to or is similar to the stacked shape of the electrode assembly housed therein.

[0059] Reference Figure 2 An insertion groove 310 can be formed on the outer surface of the secondary battery 300, which is recessed to a predetermined depth from one end edge along one direction.

[0060] An insertion slot 310 can be formed along the width or length of the secondary battery 300.

[0061] By forming a step around the first electrode assembly and the second and third electrode assemblies stacked on the first electrode assembly, such that the housing corresponds to the step, an insertion groove 310 can be formed on the outer surface of the housing.

[0062] The secondary battery 300 is accommodated such that the insertion slot 310 faces the bottom surface of the receiving portion 110, therefore the bottom surface of the insertion slot 310 can be spaced apart from the bottom surface of the receiving portion 110 by the depth of the insertion slot 310. The insertion unit 400 can be inserted into the insertion slot 310.

[0063] Reference Figure 2 The insertion unit 400 is configured to separate the secondary battery 300 inserted into the receiving portion 110 of the main body portion 100 from the receiving portion 110. The insertion unit 400 may be configured to prevent damage when the secondary battery 300 is separated from the receiving portion 110.

[0064] The insertion unit 400 may include an operation part 410 and a deformation part 420.

[0065] Reference Figures 2 to 4The insertion unit 400 may include a curved shape. The operating part 410 may be formed to bend at a predetermined angle relative to the deformable part 420 at its end. Since the operating part 410 is formed to bend at a predetermined angle relative to the deformable part 420, one end of the operating part 410 is operated to move away from the secondary battery 300, such that the other end of the operating part 410 connected to the deformable part 420 can apply a force in the direction of compressing the deformable part 420, and the deformable part 420 under the applied force can deform due to the operating part 410.

[0066] The operating part 410 can be formed to extend from the deformed part 420 along the thickness direction of the secondary battery 300 on one side of the secondary battery 300. Since the length of the operating part 410 is formed to be longer than the depth of the receiving part 110, the operating part 410 can be formed to protrude from the receiving part 110. The operating part 410 protruding from the receiving part 110 can be held and operated by the user.

[0067] The operating part 410 can be formed of a rigid material so that its shape will not deform even when the user holds and operates the operating part 410. When the user operates one end of the operating part 410 to move it away from the secondary battery 300, the operating part 410 can contact the inner wall edge of the receiving part 110, and the length of the operating part 410 is longer than the depth of the receiving part 110, so that the operating part 410 is supported by the inner wall edge of the receiving part 110 that contacts the operating part 410, and can apply force in the direction of the compression deformation part 420 by lever principle.

[0068] The operating part 410 can be formed of a rigid material so that the shape of the operating part 410 will not deform even when a force is applied and the force can be applied to the deformable part 420, and it can be formed of, for example, plastic, metal, etc., but is not limited thereto. The operating part 410 can be formed to have a higher rigidity than the deformable part 420.

[0069] The deformable part 420 deforms in the insertion groove 310 according to the operation of the operation part 410, and the deformable part 420 can be configured to separate the secondary battery 300 from the receiving part 110.

[0070] The deformable part 420 is formed to extend from the operating part 410 and can be provided along the length or width direction of the secondary battery 300.

[0071] The deformable part 420 can be configured to be inserted into the insertion slot 310. Since the insertion slot 310 is formed in the secondary battery 300, even after the deformable part 420 is inserted into the insertion slot 310 and the secondary battery 300 is housed in the receiving part 110, the problem of damage to the secondary battery 300 due to the thickness of the deformable part 420 can be prevented.

[0072] According to the operation of the operation unit 410, the deformation part 420 is subjected to a compressive force along the length direction, and at least a portion of the deformation part 420 subjected to the force deforms protrudingly toward the secondary battery 300, and the secondary battery 300 can be pushed outward from the receiving part 110 to separate the secondary battery 300 from the receiving part 110.

[0073] The deformable part 420 may include an elastically deformable material to elastically deform according to the operation of the operating part 410. For example, the material of the deformable part 420 may be, but is not limited to, plastic, metal, etc.

[0074] The operating part 410 can be formed to have higher rigidity than the deformable part 420, so that its shape will not be deformed according to the user's operation, and all force can be applied to the deformable part 420.

[0075] The deformable portion 420 may include a joint portion 421 and a non-joint portion 422.

[0076] A connecting portion 421 is formed at the end of the deformable portion 420 and can be configured to engage with a surface of the secondary battery 300. The position of the connecting portion 421 on a surface of the secondary battery 300 is fixed, such that when the deformable portion 420 is deformed by the operation of the operating portion 410, the deformable portion 420 can be guided to deform into a convex shape toward the secondary battery 300. More specifically, the connecting portion 421 can engage with a surface of the insertion groove 310 of the secondary battery 300.

[0077] For example, the joint 421 may be formed at the end of the insertion groove 310, but is not limited thereto.

[0078] The non-joining portion 422 is the area in the deformed portion 420 that is not joined to the secondary battery 300, and can be formed to extend from the joining portion 421 along the insertion groove 310.

[0079] A non-connecting portion 422 is disposed between the connecting portion 421 and the operating portion 410. If the deformable portion 420 is subjected to compressive force according to the operation of the operating portion 410, the end of the non-connecting portion 422 is fixed to the secondary battery 300 through the connecting portion 421. Therefore, the non-connecting portion 422 can be deformed by bending protruding toward the secondary battery 300. The non-connecting portion 422 with the deformable shape can push the secondary battery 300 outward from the receiving portion 110 to separate the secondary battery 300 from the receiving portion 110.

[0080] In addition, since the non-joint portion 422 is formed of an elastically deformable material, the non-joint portion 422 can buffer any impact that the secondary battery 300 can receive when the secondary battery 300 is pushed out, thereby minimizing damage to the secondary battery 300.

[0081] The non-connecting portion 422 is disposed between the secondary battery 300 and the bottom surface of the receiving portion 110, and the lower surface of the secondary battery 300 in contact with the non-connecting portion 422 can be pushed outward toward the receiving portion 110, thereby preventing the secondary battery 300 from warping or bending when it is separated from the receiving portion 110 and causing damage to the electrode assembly housed therein.

[0082] Example 2 Reference Figure 5 and Figure 6 As an embodiment 2 according to the present disclosure, the electronic device may include a main body 100, a cover, a secondary battery 300, and an insertion unit 500.

[0083] The descriptions of the main body 100, the cover, and the secondary battery 300 are the same as those described above, and therefore can be substituted.

[0084] The insertion unit 500 may include an operation part 510 and a deformation part 520.

[0085] The insertion unit 500 may include a curved shape. An operating portion 510 is formed at both ends of the deformable portion 520 and may be formed to be bent at a predetermined angle relative to the deformable portion 520. Because the operating portion 510 is formed to be bent at a predetermined angle relative to the deformable portion 520, one end of the operating portion 510 is operated to move away from the secondary battery 300, such that the other end of the operating portion 510 connected to the deformable portion 520 can apply a force in the direction of compressing the deformable portion 520, and the deformable portion 520 subjected to the applied force can deform due to the operating portion 510.

[0086] The operating part 510 can be formed symmetrically with the two ends of the deformable part 520.

[0087] The operating part 510 can be formed to extend from the deformed part 520 along the thickness direction of the secondary battery 300 on both sides of the secondary battery 300. Since the length of the operating part 510 is longer than the depth of the receiving part 110, the operating part 510 can be formed to protrude from the receiving part 110. The operating part 510 protruding from the receiving part 110 can be held and operated by the user.

[0088] The operating part 510 can be formed of a rigid material so that its shape will not deform even when the user holds and operates the operating part 510. When the user operates one end of the operating part 510 to move it away from the secondary battery 300, the operating part 510 can contact the inner wall edge of the receiving part 110, and the length of the operating part 510 is longer than the depth of the receiving part 110, so that the operating part 510 is supported by the inner wall edge of the receiving part 110 that contacts the operating part 510, and a force can be applied in the direction of the compression deformation part 520 by lever principle.

[0089] The operating part 510 can be formed of a rigid material so that the shape of the operating part 510 will not deform even when a force is applied and the force can be applied to the deformable part 520, and it can be formed of, for example, plastic, metal, etc., but is not limited thereto. The operating part 510 can be formed to have a higher rigidity than the deformable part 520.

[0090] The deformable part 520 deforms according to the operation of the operation part 510, and the deformable part 520 can be configured to separate the secondary battery 300 from the receiving part 110.

[0091] The deformable part 520 is formed to extend from the operating part 510 and can be provided along the length or width direction of the secondary battery 300.

[0092] The deformable part 520 can be configured to be inserted into the insertion slot 310. Since the insertion slot 310 is formed in the secondary battery 300, even after the deformable part 520 is inserted into the insertion slot 310 and the secondary battery 300 is housed in the receiving part 110, the problem of damage to the secondary battery 300 due to the thickness of the deformable part 520 can be prevented.

[0093] According to the operation of the operation portion 510 formed on both sides of the deformable portion 520, the deformable portion 520 is subjected to a compressive force along the length direction, and at least a portion of the deformable portion 520 subjected to the force deforms protruding towards the secondary battery 300, and the secondary battery 300 can be pushed outward from the receiving portion 110 to separate the secondary battery 300 from the receiving portion 110.

[0094] The deformable part 520 may include an elastically deformable material to elastically deform according to the operation of the operating part 510. For example, it may be, but is not limited to, plastic, metal, etc.

[0095] The operating part 510 can be formed to have higher rigidity than the deformable part 520, so that its shape will not be deformed according to the user's operation, and full force can be applied to the deformable part 520.

[0096] The deformable portion 520 may include a joining portion 521 and a non-jointing portion 522.

[0097] The engagement portion 521 is formed near the center of the deformable portion 520 in the longitudinal direction and can be configured to engage with a surface of the secondary battery 300. The position of the engagement portion 521 on the surface of the secondary battery 300 is fixed, such that when the deformable portion 520 is deformed due to the operation of the operating portion 510, the deformable portion 520 can be guided to deform into a convex shape toward the secondary battery 300. More specifically, the engagement portion 521 can engage with the center of the insertion groove 310 of the secondary battery 300 in the longitudinal direction.

[0098] For example, the joint 521 may be formed at the center of the insertion groove 310, but is not limited thereto.

[0099] When the deformable part 520 deforms, the joint part 521 can be pushed out of the receiving part along with the non-joint part 522.

[0100] The non-joining portion 522 is the area in the deformable portion 520 that is not joined to the secondary battery 300, and can be formed to extend along the insertion groove 310 in two directions from the joining portion 521 located near the center of the deformable portion 520.

[0101] A non-connecting portion 522 is disposed between the connecting portion 521 and the operating portion 510. If the deformable portion 520 is subjected to compressive force according to the operation of the operating portion 510, the end of the non-connecting portion 522 is fixed to the secondary battery 300 through the connecting portion 521. Therefore, the non-connecting portion 522 can be deformed by bending protruding toward the secondary battery 300. The non-connecting portion 522 with the deformable shape can push the secondary battery 300 outward from the receiving portion 110 together with the connecting portion 521 to separate the secondary battery 300 from the receiving portion 110.

[0102] Since the non-jointing portion 522 is provided between the secondary battery 300 and the bottom surface of the receiving portion 110, in the event of deformation, the non-jointing portion 522 pushes the secondary battery 300 from the bottom of the secondary battery 300 toward the outside of the receiving portion 110. Therefore, compared with the case where a structure is installed in the gap between the end of the secondary battery 300 and the receiving portion 110 to separate the secondary battery 300 from the receiving portion 110, damage to the secondary battery 300 can be reduced. In addition, by means of the operating portions 510 symmetrically provided at both ends of the deformable portion 520, the deformable portion 520 can be guided to deform symmetrically based on the joining portion 521, so that the secondary battery 300 can separate from the receiving portion 110 while a uniform force is applied.

[0103] The deformable part 520 is provided between the secondary battery 300 and the bottom surface of the receiving part 110, and can be pushed outward of the receiving part 110 to the vicinity of the center of the lower surface of the secondary battery 300, thereby preventing the secondary battery 300 from warping or bending when it is separated from the receiving part 110 and causing damage to the electrode assembly contained therein.

[0104] Example 3 Reference Figure 7 As an embodiment 3 according to the present disclosure, the electronic device 11 may include a main body 100, a secondary battery 300, and an insertion unit 600.

[0105] The description of the cover and secondary battery 300 is the same as that described above, and therefore can be substituted.

[0106] The main body 100 may include electronic components required for the electrically driven electronic device 11.

[0107] In the main body 100, a recessed receiving portion 110 may be formed to accommodate a secondary battery 300 that serves as a power source for driving electronic components.

[0108] The insertion unit 600 is configured to separate the secondary battery 300 inserted into the receiving portion 110 of the main body portion 100 from the receiving portion 110. The insertion unit 600 may be configured to prevent damage when the secondary battery 300 is separated from the receiving portion 110.

[0109] The insertion unit 600 is installed in the receiving portion 110 and can be configured to separate the secondary battery 300 from the receiving portion 110 as the insertion unit 600 deforms.

[0110] The insertion unit 600 may include an operation part 610 and a deformation part 620.

[0111] Reference Figure 8 and Figure 9 The insertion unit 600 may include a curved shape. The operating part 610 may be formed to bend at a predetermined angle relative to the deformable part 620 at its end. Since the operating part 610 is formed to bend at a predetermined angle relative to the deformable part 620, one end of the operating part 610 is operated to move away from the secondary battery 300, such that the other end of the operating part 610 connected to the deformable part 620 can apply a force in the direction of compressing the deformable part 620, and the deformable part 620 under the applied force can deform due to the operating part 610.

[0112] The operating part 610 can be formed to extend from the deformed part 620 along the thickness direction of the secondary battery 300 on one side of the secondary battery 300. Since the length of the operating part 610 is longer than the depth of the receiving part 110, the operating part 610 can be formed to protrude from the receiving part 110. The operating part 610 protruding from the receiving part 110 can be held and operated by the user.

[0113] The operating part 610 can be formed of a rigid material so that its shape will not deform even when the user holds and operates the operating part 610. When the user operates one end of the operating part 610 to move it away from the secondary battery 300, the operating part 610 can contact the inner wall edge of the receiving part 110, and the length of the operating part 610 is longer than the depth of the receiving part 110, so that the operating part 610 is supported by the inner wall edge of the receiving part 110 that contacts the operating part 610, and can apply force in the direction of the compression deformation part 620 by lever principle.

[0114] The operating part 610 can be formed of a rigid material so that the shape of the operating part 610 will not deform even when a force is applied and the force can be applied to the deformable part 620. It can be formed of, for example, plastic, metal, etc., but is not limited thereto. The operating part 610 can be formed to have a higher rigidity than the deformable unit 620.

[0115] The deformable part 620 deforms in the insertion groove 310 according to the operation of the operation part 610, and the deformable part 620 can be configured to separate the secondary battery 300 from the receiving part 110.

[0116] The deformable part 620 is formed to extend from the operating part 610 and can be provided along the length or width direction of the secondary battery 300.

[0117] The deformable part 620 can be configured to be inserted into the insertion slot 310. Since the insertion slot 310 is formed in the secondary battery 300, even after the deformable part 620 is inserted into the insertion slot 310 and the secondary battery 300 is housed in the receiving part 110, the problem of damage to the secondary battery 300 due to the thickness of the deformable part 620 can be prevented.

[0118] According to the operation of the operation unit 610, the deformation part 620 is subjected to a compressive force along the length direction, and at least a portion of the deformation part 620 subjected to the force deforms protrudingly toward the secondary battery 300, and the secondary battery 300 can be pushed outward from the receiving part 110 to separate the secondary battery 300 from the receiving part 110.

[0119] The deformable part 620 may include an elastically deformable material to elastically deform according to the operation of the operating part 610. For example, it may be, but is not limited to, plastic, metal, etc.

[0120] The operating part 610 can be formed to have higher rigidity than the deformable part 620, so that its shape will not be deformed according to the user's operation, and full force can be applied to the deformable part 620.

[0121] The deformable part 620 may include a fixed part 621 and a non-fixed part 622.

[0122] The fixing part 621 is located at one end of the non-fixed part 622 and can be configured to be fixed to one side of the receiving part 110. The position of the fixing part 621 on one surface of the secondary battery 300 is fixed, such that when the deformable part 620 is deformed due to the operation of the operating part 610, the deformable part 620 can be guided to deform into a convex shape toward the secondary battery 300. More specifically, the fixing part 621 can engage with one surface of the insertion groove 310 of the secondary battery 300.

[0123] For example, the fixing part 621 may be formed at one end of the receiving part 110, but is not limited thereto.

[0124] The non-fixed portion 622 is the area that is not fixed to the receiving portion 110, and can be formed to extend from the fixed portion 621 in one direction.

[0125] A non-fixed portion 622 is disposed between the fixed portion 621 and the operating portion 610. If the deformable portion 620 is subjected to compressive force according to the operation of the operating portion 610, the end of the deformable portion 620 is fixed to the receiving portion 110 by the fixed portion 621. Therefore, the non-fixed portion 622 can be deformed by bending protruding toward the secondary battery 300. The non-fixed portion 622 with the deformable shape can push the secondary battery 300 outward from the receiving portion 110 to separate the secondary battery 300 from the receiving portion 110.

[0126] Since the non-fixed portion 622 is provided between the secondary battery 300 and the bottom surface of the receiving portion 110, in the event of deformation, the non-fixed portion 622 pushes the secondary battery 300 from the bottom of the secondary battery 300 toward the outside of the receiving portion 110. Therefore, compared to the case where a structure is installed in the gap between the end of the secondary battery 300 and the receiving portion 110 to separate the secondary battery 300 from the receiving portion 110, damage to the secondary battery 300 can be reduced. In addition, the deformable portion 620 is provided between the secondary battery 300 and the bottom surface of the receiving portion 110, and can push the secondary battery 300 toward the center of the lower surface of the receiving portion 110, thereby preventing the secondary battery 300 from warping or bending when it separates from the receiving portion 110 and from damaging the electrode assembly housed therein.
