Detailed Implementation

[0028] In the following, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. The terms or words used in this specification and claims should not be construed as having a general or dictionary meaning, but should be interpreted as consistent with the technical concept of the present disclosure, based on the principle that the inventor can, as his / her own lexicographer, appropriately define the concepts of the terms to best describe his / her invention.

[0029] The embodiments described in this specification and the constructions shown in the accompanying drawings are only some of the embodiments of this disclosure and do not represent all aspects of this disclosure. Therefore, it should be understood that various equivalents and modifications may exist to replace or modify the one or more embodiments described herein at the time of filing of this application.

[0030] It will be understood that if an element or layer is referred to as being "on," "connected to," or "bonded to" another element or layer, it can be directly on, directly connected to, or directly bonded to said other element or layer, or one or more intermediary elements or layers may be present. When an element or layer is referred to as being "directly on," "directly connected to," or "directly bonded to" another element or layer, no intermediary element or layer is present. For example, if a first element is described as being "bonded" or "connected" to a second element, the first element can be directly bonded to or directly connected to the second element, or the first element can be indirectly bonded to or indirectly connected to the second element via one or more intermediary elements.

[0031] In the figures, the dimensions of various elements, layers, etc., may be exaggerated for clarity. The same reference numerals denote the same elements. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items. Furthermore, the use of "may" refers to "one or more embodiments of this disclosure" when describing embodiments of the present disclosure. Expressions such as "at least one of..." and "any one of..." modify the entire list of elements, not individual elements within that list, if following a list of elements. When phrases such as "at least one of A, B, and C", "at least one of A, B, or C", "at least one selected from the group of A, B, and C", or "at least one selected from A, B, and C" are used to specify a list of elements A, B, and C, the phrase may refer to any suitable combination (or subset) of A, B, and C, and all suitable combinations (or subsets), such as A, B, C, A and B, A and C, B and C, or A and B and C. As used herein, the term "use" and its variations may be considered synonymous with the term "utilize" and its variations, respectively. As used herein, the terms "substantially," "about," and similar terms are used as approximate terms rather than as terms of degree, and are intended to explain the inherent variations in measured or calculated values ​​that will be recognized by one of ordinary skill in the art.

[0032] It will be understood that although the terms first, second, third, etc., may be used herein to describe various elements, components, regions, layers, and / or portions, these elements, components, regions, layers, and / or portions should not be limited by these terms. These terms are used to distinguish one element, component, region, layer, or portion from another element, component, region, layer, or portion. Therefore, without departing from the teachings of the exemplary embodiments, the first element, first component, first region, first layer, or first portion discussed below may be referred to as a second element, second component, second region, second layer, or second portion.

[0033] For ease of description, spatial relative terms such as “below,” “under,” “lower,” “above,” and “upper” may be used herein to describe the relationship between one element or feature as shown in the figures and another element or feature(s). It will be understood that, in addition to the orientation depicted in the figures, the spatial relative terms are intended to cover different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “below” or “under” other elements or features will subsequently be oriented “above” or “above” said other elements or features. Thus, the term “below” can cover both above and below orientations. The device may be otherwise oriented (rotated 90 degrees or in other orientations), and the spatial relative descriptive terms used herein should be interpreted accordingly.

[0034] The terminology used herein is for the purpose of describing embodiments of this disclosure and is not intended to be limiting of this disclosure. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “an” are also intended to include the plural forms. It will also be understood that if the terms “comprising,” “including,” and / or variations thereof are used in this specification, it indicates the presence of the stated features, integers, steps, operations, elements, and / or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0035] Furthermore, any numerical range disclosed and / or described herein is intended to include all subranges containing the same numerical precision within the described range. For example, the range “1.0 to 10.0” is intended to include all subranges between the described minimum value of 1.0 and the described maximum value of 10.0 (and including both the described minimum value of 1.0 and the described maximum value of 10.0), i.e., having a minimum value equal to or greater than 1.0 and a maximum value equal to or less than 10.0, such as 2.4 to 7.6. Any maximum numerical limit described herein is intended to include all lower numerical limits contained therein, and any minimum numerical limit described in this specification is intended to include all higher numerical limits contained therein. Therefore, the applicant reserves the right to modify this specification and the claims to expressly describe any subranges contained within the range expressly described herein. All such ranges are intended to be inherently described in this specification such that modifications to expressly describe any such subranges will be compliant.

[0036] Referring to two compared elements, features, etc., as “identical” can mean that they are “substantially identical.” Therefore, the phrase “substantially identical” can include cases with a deviation considered low in the art, such as 5% or less. Additionally, if a parameter is said to be uniform in a given region, it can mean that it is uniform in terms of the mean.

[0037] Throughout this specification, unless otherwise stated, each element may be singular or plural.

[0038] Arranging any element "above (or below)" or "on (below)" another element can mean that the arbitrary element can contact the upper (or lower) surface of the element, and that the other element can also be placed between the element and the arbitrary element positioned on (or below) the element.

[0039] Additionally, it will be understood that if a component is referred to as “linked,” “combined,” or “connected” to another component, then the elements can be directly “combined,” “linked,” or “connected” to each other, or another component can be “placed” between the components.

[0040] Throughout this specification, unless otherwise stated, if "A and / or B" is stated, it means A, B, or A and B. That is, "and / or" includes any or all combinations of the listed items. When "C to D" is stated, unless otherwise stated, it means C or greater and D or less.

[0041] The terminology used herein is for the purpose of describing embodiments of this disclosure and is not intended to limit the disclosure.

[0042] Batteries embedded in products such as mobile phones, tablet PCs, and other electrical devices can be attached to the battery mounting section of the product using double-sided tape. Once attached with double-sided tape, the battery is not easily separated, and forcibly pulling it apart can cause the external material to crack or the electrode terminals to be damaged, posing safety concerns and environmental problems because the battery cannot be recycled. Recently, international standards requiring easy separation of batteries from products have been established.

[0043] Meanwhile, a pouch battery, a type of battery, is manufactured by housing the electrode assembly in a pouch, injecting electrolyte, sealing the sides of the pouch, and folding the sealed portion.

[0044] Figure 1 This is a schematic diagram illustrating an example of the electrode assembly of a battery (e.g., a secondary battery).

[0045] Electrode assembly 10 can be formed by winding or stacking a first electrode plate 11, a diaphragm 12, and a second electrode plate 13, which are formed as a thin plate or film. When electrode assembly 10 is a wound stack, the winding axis can be parallel to the length direction of the housing. In other embodiments, electrode assembly 10 can be a stack type instead of a wound type, and the shape of electrode assembly 10 is not limited in this disclosure. Additionally, electrode assembly 10 can be a Z-stacked electrode assembly in which positive and negative electrode plates are inserted into both sides of a diaphragm that is later bent into a Z-stack. Furthermore, one or more electrode assemblies can be stacked such that the long sides of the electrode assemblies are adjacent to each other and housed in a housing, and the number of electrode assemblies in the housing is not limited in this disclosure. The first electrode plate 11 of the electrode assembly can act as a negative electrode, and the second electrode plate 13 can act as a positive electrode. Of course, the reverse is also possible; in some embodiments, the first electrode plate 11 acts as a positive electrode, and the second electrode plate 13 acts as a negative electrode.

[0046] The first electrode plate 11 can be formed by applying a first electrode active material (such as graphite or carbon) to a first electrode current collector formed of a metal foil (such as copper, copper alloy, nickel, or nickel alloy). The first electrode tab 14 can be connected to an external first terminal (not shown). In some embodiments, when manufacturing the first electrode plate 11, the first electrode tab 14 can be formed by pre-cutting it to protrude toward one side of the electrode assembly 10, or the first electrode tab 14 can protrude toward one side of the electrode assembly 10 more than the diaphragm 12 (e.g., further than or beyond the diaphragm 12) without being separately cut.

[0047] The second electrode plate 13 can be formed by applying a second electrode active material (such as a transition metal oxide) onto a second electrode current collector formed of a metal foil (such as aluminum or an aluminum alloy). The second electrode plate 13 may include a second electrode tab 15 (e.g., a second uncoated portion) as a region where the second electrode active material is not applied. The second electrode tab 15 may be connected to an external second terminal (not shown). In some embodiments, when manufacturing the second electrode plate 13, the second electrode tab 15 may be formed by pre-cutting it to protrude toward the other side of the electrode assembly 10 (e.g., the side opposite to the first electrode tab 14), or the second electrode plate 13 may protrude toward the other side of the electrode assembly more than the diaphragm 12 (e.g., farther or beyond the diaphragm 12) without being separately cut.

[0048] In some embodiments, the first electrode tab 14 may be positioned on the upper side of the electrode assembly 10, and the second electrode tab 15 may be positioned on the lower side of the electrode assembly 10. In other embodiments, the first electrode tab 14 and the second electrode tab 15 may be positioned on one side of the electrode assembly 10 in the same direction.

[0049] Here, for ease of description, according to... Figure 1 The oriented electrode assembly 10 defines the upper and lower sides, and its position can be changed when the secondary battery is rotated left and right or up and down.

[0050] The diaphragm 12 prevents short circuits between the first electrode plate 11 and the second electrode plate 13, while allowing lithium ions to move between the first electrode plate 11 and the second electrode plate 13. The diaphragm 12 can be made of, for example, a polyethylene film, a polypropylene film, a polyethylene-polypropylene film, etc.

[0051] In some embodiments, the electrode assembly 10 may be housed together with the electrolyte in a housing (not shown). In the case of a pouch cell, the electrode assembly 10 may be... Figure 2 The form shown is housed in a bag made of flexible material. In the case of cylindrical or prismatic secondary batteries, the electrode assembly 10 can be... Figure 3and Figure 4 The form shown is housed in a cylindrical or prismatic metal casing.

[0052] Examples of materials that can be used in secondary batteries (e.g., lithium secondary batteries) according to this disclosure are described herein.

[0053] As the positive electrode active material, compounds capable of reversibly inserting / deintercalating lithium (e.g., lithiation intercalation compounds) can be used. For example, at least one of lithium and a composite oxide of a metal selected from cobalt, manganese, nickel, and combinations thereof can be used.

[0054] The composite oxide can be a lithium transition metal composite oxide, and examples of it can include lithium nickel oxides, lithium cobalt oxides, lithium manganese oxides, lithium iron phosphate compounds, cobalt-free lithium nickel manganese oxides, or combinations thereof.

[0055] As an example, a compound represented by any of the following formulas can be used: Li a A 1-b X b O 2-c D c (0.90≤a≤1.8, 0≤b≤0.5, 0≤c≤0.05); Li a Mn 2-b X b O 4-c D c (0.90≤a≤1.8, 0≤b≤0.5, 0≤c≤0.05); Li a Ni 1-b-c Co b X c O 2-α D α (0.90≤a≤1.8, 0≤b≤0.5, 0≤c≤0.5, 0<α<2); Li a Ni 1-b-c Mn b X c O 2-α D α (0.90≤a≤1.8, 0≤b≤0.5, 0≤c≤0.5, 0<α<2); Li a Ni b Co c L 1 d G e O2 (0.90≤a≤1.8, 0≤b≤0.9, 0≤c≤0.5, 0≤d≤0.5, 0≤e≤0.1); Li a NiG b O2 (0.90≤a≤1.8, 0.001≤b≤0.1); Lia CoG b O2 (0.90≤a≤1.8, 0.001≤b≤0.1); Li a Mn 1-b G b O2 (0.90≤a≤1.8, 0.001≤b≤0.1); Li a Mn2G b O4 (0.90≤a≤1.8, 0.001≤b≤0.1); Li a Mn 1-g G g PO4 (0.90≤a≤1.8, 0≤g≤0.5); Li (3-f) Fe2(PO4)3 (0≤f≤2); and Li a FePO4 (0.90≤a≤1.8).

[0057] The positive electrode for a lithium secondary battery may include a current collector and a layer of positive electrode active material formed on the current collector. The positive electrode active material layer may include a positive electrode active material and may also include a binder and / or a conductive material.

[0058] Based on a 100wt% positive electrode active material layer, the content of the positive electrode active material is in the range of about 90wt% to about 99.5wt%, and based on the 100wt% positive electrode active material layer, the contents of the binder and the conductive material are in the range of about 0.5wt% to about 5wt%, respectively.

[0059] The current collector can be aluminum (Al), but is not limited to this.

[0060] The negative electrode active material may include materials capable of reversibly inserting / deintercalating lithium ions, lithium metal, lithium metal alloys, materials capable of doping and dedoping lithium, or transition metal oxides.

[0061] Materials capable of reversibly inserting / deintercalating lithium ions can be carbon-based negative electrode active materials, including, for example, crystalline carbon, amorphous carbon, or combinations thereof. Examples of crystalline carbon can include graphite, such as natural or artificial graphite, and examples of amorphous carbon can include soft carbon, hard carbon, pitch carbides, mesophase pitch carbides, sintered coke, etc.

[0062] An Si-based negative electrode active material or an Sn-based negative electrode active material can be used as a material capable of doping and de-doping lithium. The Si-based negative electrode active material can be silicon, a silicon-carbon composite, SiO x (0 < x < 2), an Si-based alloy, or a combination thereof.

[0063] The silicon-carbon composite can be a composite of silicon and amorphous carbon. According to one embodiment, the silicon-carbon composite can be in the form of silicon particles and amorphous carbon coated on the surface of the silicon particles.

[0064] The silicon-carbon composite can also include crystalline carbon. For example, the silicon-carbon composite can include a core and an amorphous carbon coating layer on the surface of the core that includes crystalline carbon and silicon particles.

[0065] The negative electrode for a lithium secondary battery can include a current collector and a negative electrode active material layer provided on the current collector. The negative electrode active material layer can include a negative electrode active material and can also include a binder and / or a conductive material.

[0066] For example, the negative electrode active material layer can include about 90 wt% to about 99 wt% of the negative electrode active material, about 0.5 wt% to about 5 wt% of the binder, and about 0 wt% to about 5 wt% of the conductive material.

[0067] A non-aqueous binder, an aqueous binder, a dry binder, or a combination thereof can be used as the binder. When using an aqueous binder as the negative electrode binder, a cellulose-based compound capable of imparting viscosity can also be included.

[0068] As the negative electrode current collector, a material selected from copper foil, nickel foil, stainless steel foil, titanium foil, nickel foam, copper foam, a polymer substrate coated with a conductive metal, and a combination thereof can be used.

[0069] The electrolyte for a lithium secondary battery can include a non-aqueous organic solvent and a lithium salt.

[0070] The non-aqueous organic solvent serves as a medium through which ions involved in the electrochemical reaction of the battery can move.

[0071] The non-aqueous organic solvent can be a carbonate solvent, an ester solvent, an ether solvent, a ketone solvent, an alcohol solvent, an aprotic solvent, and can be used alone or in combination of two or more.

[0072] In addition, in the case of using a carbonate solvent, a mixture of a cyclic carbonate and a chain carbonate can be used.

[0073] Depending on the type of lithium secondary battery, a separator may be present between the first electrode plate (e.g., the negative electrode) and the second electrode plate (e.g., the positive electrode). As the separator, polyethylene, polypropylene, polyvinylidene fluoride, or multilayer films of two or more layers thereof can be used.

[0074] The membrane may include a porous substrate and a coating layer on one or both surfaces of the porous substrate, comprising organic materials, inorganic materials or combinations thereof.

[0075] Organic materials may include polyvinylidene fluoride polymers or (meth)acrylic acid polymers.

[0078] Figure 2 This is a schematic diagram showing a pouch battery.

[0079] The pouch battery includes an electrode assembly 10 and a pouch 20 for housing the electrode assembly 10.

[0080] Electrode assembly 10 and Figure 1 The electrode assemblies shown are identical. The first electrode tab 14 and the second electrode tab 15 of the electrode assembly 10 can be electrically connected by soldering to corresponding external first terminal lead 16 and second terminal lead 17. Each of the first terminal lead 16 and the second terminal lead 17 can be attached to the tab film 18 for insulation from the bag 20.

[0081] The bag 20 can be sealed together with the electrode assembly 10 housed therein by bringing the sealing portions 21 at its edges into contact with each other. In this case, the seal can be achieved using a connecting piece film 18 placed between the sealing portions 21. The sealing portions 21 of the bag 20 can all be made of a hot-melt material that generally has weak adhesion to metals. Therefore, the sealing portions 21 can be fused to the bag 20 by inserting a thin connecting piece film 18 between the sealing portions 21.

[0082] Figure 3 This is an external view of a pouch cell, showing that the sealing portion 21 is sealed and then inverted for assembly. Figure 2 The state of the upper and lower parts of bag 20 shown.

[0083] The sealing portion 21 can be folded to contact and terminate with the side surface of the battery body. As described above, the process of folding the sealing portion 21 to the side surface of the bag 20 is called side folding.

[0084] The first terminal lead 16 and the second terminal lead 17 exposed outside the bag 20 can be connected to the circuit board or electrical components of a product that uses a battery (e.g., an electrical device such as a mobile phone, tablet computer, or electric fan).

[0085] Conventionally, double-sided tape is used to attach the battery to the inside of a product in order to embed it. However, because the battery is attached with double-sided tape, it is difficult to separate later, and there is a safety hazard if the battery is forcibly removed.

[0086] Figure 4 This is a diagram illustrating an apparatus for mounting a battery according to some embodiments of the present disclosure, showing a fixing member 100 for mounting a pouch battery 200 onto a battery mounting portion 300 of a product.

[0087] The sealing portion 21 of the pouch battery 200 can be placed in an unfolded state on the battery mounting portion 300 of the product, and the fixing member 100 can be placed on the sealing portion 21 of the pouch battery 200 and secured using a fastening member 28 such as a screw. Here, the fixing member 100 may include a pressure portion 24 for pressurizing the sealing portion 21 of the pouch battery 200 and a through hole 26 through which the fastening member 28 passes.

[0088] Fastening components 28 are not limited to screws, but can also include bolts, rivets, clamps, clips, etc.

[0089] The pressure portion 24 of the fixing member 100 may be in the form of a sheet or plate, but this disclosure is not limited thereto. For example, the pressure portion 24 may be formed as a quadrilateral rod.

[0090] The pressurizing section 24 can pressurize and constrain at least a portion of the sealed portion of the pouch-type battery. That is, although... Figure 4 The diagram shows that the pressurized portion 24 of the retaining member 100 covers and pressurizes the entire sealed portion 21 of the pouch cell 200; however, in some other embodiments, the pressurized portion 24 may cover and pressurize a portion of the sealed portion 21 (e.g., see...). Figure 14 (Pressurization sections 24a, 24b).

[0091] The battery mounting portion 300 of the product may be provided with a fastening hole 30, to which a fastening member 28 passing through the through hole 26 of the pressurizing portion 24 is fastened. The fastening hole 30 may be pre-formed to allow the insertion of a fastening member 28 such as a screw or bolt, or may be forcibly formed when the pressurizing portion 24 is secured by the fastening member 28.

[0092] The through-hole 26 of the fixing member 100 may be formed at a position further outward than the outer periphery of the sealing portion 21 to prevent damage to the sealing portion 21 of the pouch battery 200. In cases where clips or jigs are used as fastening members instead of screws, bolts, or rivets, the through-hole may not be necessary in the pressure portion 24.

[0093] The fixing member 100, including the pressurized portion 24, can be made of a metal or non-metal (e.g., synthetic resin, wood, laminated paper, etc.) that has the rigidity required to fix the pouch cell 200. Additionally, the metal or non-metal material can have insulating properties, but this disclosure is not limited thereto.

[0094] Figure 5 This diagram shows the state in which the pressure portion 24 of the fixing member 100 is placed on the sealing portion 21 of the pouch battery 200 and fastened to the battery mounting portion 300 of the product using the fastening member 28.

[0095] Since the pouch battery 200 is not attached to the product using double-sided tape or similar materials, it can be easily separated from the product's mounting portion 300 by loosening the fastening member 28. This eliminates the risk factors caused by battery damage, allows for the recycling of the separated battery, and keeps the product's interior clean after separation.

[0096] Figure 6 It is along Figure 5 A sectional view of line A-A'.

[0097] like Figure 6 As shown, the lateral width w2 of the pressurizing portion 24 of the fixing member 100 is greater than the lateral width of the sealing portion 21 of the pouch battery 200, that is, the distance w1 protruding from the side surface. Figure 6 In this case, since the entire surface of the sealing portion 21 is covered by the pressurized portion 24, there is no possibility of damaging the sealing portion 21, so the sealing state of the pouch battery 200 is not affected.

[0098] Figure 6 It also shows that when screws, bolts, rivets, etc. are used as fastening components 28, through holes 26 may be positioned to avoid the sealing portion 21.

[0099] Figure 7 This is a diagram illustrating a fixing member 100 of a device for mounting a battery according to some other embodiments of the present disclosure.

[0101] The pressing portion 24 of the fixing member 100 may press and fix the sealing portion 21 of the pouch-type battery 200 by pressing the sealing portion 21 from top to bottom, and the side wall 32 may support the side surface of the main body of the pouch-type battery 200 to prevent the horizontal shaking of the pouch-type battery 200, thereby further increasing the mounting rigidity.

[0102] As described herein, the fixing member 100 including the pressing portion 24 and the side wall 32 may be made of metal or non-metal (e.g., synthetic resin, wood, laminated paper, etc.). Additionally, the metal or non-metal material may have insulating properties, but the present disclosure is not limited thereto.

[0103] Figure 8 is Figure 7 a front view of, which shows the pouch-type battery 200 mounted on a product using the fixing member 100. In Figure 8 the height h1 of the pouch-type battery 200 may be equal to or different from the height h2 of the side wall 32. For example, when the side wall 32 should not interfere with other structures located on the upper surface of the pouch-type battery 200, h1>h2 or h1 = h2 may be adopted, and h1 < h2 may be intentionally adopted such that the side wall 32 is used to prevent other structures from contacting the upper surface of the pouch-type battery 200.
