Description of the Invention (1) Field of the Invention The present invention relates to batteries (such as lithium ion batteries) and prepared batteries (such as lithium ion batteries, lithium polymer batteries, and lithium metals). Battery). The present invention also relates to a case for a battery (like a lithium ion battery) and a method for preparing the case for a battery (like a lithium ion battery, a lithium polymer battery, and a lithium metal battery). — *, Question § Inch Theory At present, lithium-ion batteries are enclosed in hard aluminum cases, which are formed by impact molding or deep drawing. This hard case uses laser welding to keep the electrolyte in the aluminum case and to prevent the chemicals in the case from being exposed to moisture and other gases that will reduce battery performance. These enclosures are expensive to manufacture, and the number of companies that can be manufactured is extremely limited. What's more, the available shape and type factors are very limited. For example, the thickness of the case cannot be achieved below six millimeters. Excessive prices and restrictions on size, shape, and thickness have driven battery developers to explore new ways to protect and package this lithium-ion battery and lithium polymer battery. Flexible inlay-plastic laminates are now available. Its low price, the ability to provide the desired deep groove forming ability, a wide range of sources, and its high protection against moisture and gases, understandably, this material has attracted attention and is a kind of memory. Moreover, the ease of changing the dimensions of these shapes (ie, length, width, and thickness) provides the most powerful argument for choosing this material. Compared with the present invention, the metal case used in batteries today is both heavy and thick. These properties (weight and thickness) are important for new battery designs because batteries must be able to fit into very small appliances, such as mobile phones, laptops, palmtop computers, laptops, cameras, and so on. Gradually, the weight and size have become the standard for this paper (CNS> A4 specification (21 × 297mm) -4 (Please read the precautions on the back before filling in this page)

Description of the Invention () Factors that customers prioritize when choosing appliances. In addition, the performance of the battery itself is another determining factor in the sale of this product. In recent years, the inventors of this case and other inventors have designed and provided new laminates for the initial type of this case. These laminates are designed for cold work, like rectangular straight wall grooves to accommodate the bipolar battery, or designed as pouches, typical three-sided or fin-sealed bags with a thin structure. The shape of this bag is familiar Enclosure technicians are familiar. All these materials have many characteristics in common: They contain aluminum foil as a barrier material that blocks gas (such as water vapor and oxygen) and light, and prevents the electrolyte from evaporating from the battery for a long time. Apart from that, they have only minor changes compared to the type first produced by the flexible aluminum housing company of Ualus in 1992. The composition of the latter is as follows: Formable oriented polyamide (〇PA), 25 micron (outer layer) Adhesive aluminum foil, 45 to 60 micron bonding layer polyethylene terephthalate or oriented polyamide, 12 to 25 micron bonding Layer sealant, 50 micron (inner layer) Sealant, 50 micron (inner layer) For a long time, along with the development of battery technology itself, some limited changes have been made in the connection layer, the thickness of the sealant and the foil. Even this paper size is applicable to Chinese National Standard (CNS) A4 (210X 297 mm) (Please read the precautions on the back before filling this page)

Description of the invention () The structure has also been improved. Typically, the choice of sealant depends on the battery and its electrolyte chemistry and the method of making acrylic-modified polyethylene or polypropylene. Therefore, the choice of the connecting layer also depends on the above-mentioned sealants, electrolytes, shell types selected from epoxy-urethane or aliphatic polyester adhesives, and protruding acrylic-modified polyethylene and maleic anhydride-modified polymers. Depending on the connection layer of acrylic. The interlayer film of the sealant thickness and the inner surface of the structure, such as polyethylene terephthalate (PET) or oriented polyamide (oPA) film, is designed for the thickness of the relevant tabs. The connecting piece is made of nickel, copper, aluminum or stainless steel. The tabs are sealed between the sides of the housing (like the upper and lower sides of the molding groove or the front and back of the bag-shaped housing). The tabs lead the anode and cathode of the battery to the outside, which are called the positive and negative electrodes, respectively. The tab area forms the most complicated part of the battery case. As with existing hard aluminum cases, Ming-Plastic laminates must provide a very tight seal around the tabs to prevent electrolyte from leaking out of the case. At the same time, moisture must be prevented from entering along the same splice. Add an intermediate plastic film, such as an oriented polyurethane film or a polyethylene phthalate film, to ensure that the sealant material in the tab area will not be squeezed into contact with the aluminum foil in the shell during sealing. point. At the point of contact, the battery will short-circuit. Oriented polyamide or polyethylene phthalate film is incompressible at the temperatures used to seal polypropylene (PP) and polyethylene (PE), so it prevents contact between the tabs and aluminum foil. The size of the sealant film or extrudate is designed to seal tabs of different thickness ranges, but the tab thickness is mostly between 50 and 80 microns, so a tight, very thick seal will be formed. Because the sealant must be very thick, there are some significant disadvantages, as described below.

Description of the invention () · The existing materials of the project have heat-resistant and pressure-resistant films (like polyparaphthalein) Ethylene glycol or oriented polyurethane film) and sealant material (polypropylene or polyethylene copolymer), so it is very thick. The new battery is designed to minimize the size and weight of this battery. In order to maximize the volume of the battery bipolar in the molding groove, the straighter the molding wall, the better. The laminate used to protect the bipolar and contain the electrolyte case should be as thin as possible. The materials in today's technology are quite thick, so they are large and heavy, taking up a lot of valuable space. In order to reduce the volume of the battery after the sealing is completed, the sealing is typically folded downward in the case of a molded bottom, or folded along the bag body. The folding seal of the prior art materials occupies a considerable amount of space and volume due to the very thick shell material. Due to the large size of the folded seal, the volume of the remaining battery is significantly reduced. The amount of electrolyte absorbed by the sealant material (whether it is grafted or copolymerized polypropylene or polyethylene) is important, and the electrolyte is slowly evaporated. Typical electrolytes contain strong organic solvents, like alkyl carbonates, such as ethyl carbonate, dimethyl carbonate, ethyl methyl carbonate, and the like. These strong solvents are soluble in existing laminates. Therefore, as time goes by, the electrolyte found in the sealant solution, polyethylene terephthalate and oriented polyamide film and the connection layer will reduce the bonding strength to a certain extent, but more importantly, this electrolyte will also be in The sealing edges slowly evaporate to dry the battery. This battery is often exposed to temperatures up to 120 ° C (for a short period of time), at temperatures like 85 ° C (for a long-term test), and for long periods of time exposed to cycling between 60 ° C and 95T ^. (Typically, when testing at 60 ° C for a long time, the electrolyte loss with the existing case can be quite significant.)

Description of the invention () The material lacks molding ability and is easy to break at the corner of the molding groove. Molded grooves require almost straight corners (typically 4 degrees or less) which place a considerable amount of stress on the material. Usually, the lack of moldability is related to the wrong type of aluminum alloy or the wrong type of polyethylene terephthalate or polyamide film. Once the aluminum foil breaks during the molding process, it impairs the battery's barrier protection, such as preventing the electrolyte from evaporating or water from entering the case. As mentioned earlier, the main disadvantage of the shell laminates of the prior art is that the tab < area is difficult to tightly seal with the laminate. This poor seal causes electrolyte to leak out of the battery and may cause the battery and tabs to corrode due to water intrusion. In short, battery life and performance will be compromised. This difficulty arises from the fact that the sealant material must be squeezed along the flat and uniform edges of the tab during the heat sealing process. During heat sealing, the sealant must flow to plug the edges of the tabs. In doing so, there is a risk that the sealant material along the edges of the tabs is either over-pressed or under-pressed. In either case, the seal will not be tight and will cause leaks and movements that will compromise battery performance. The amount of sealant material in the splice area is constant because it is a thin metal sheet or extrudate and is an integral part of the laminate. Therefore, different thickness or size of the tabs can only be matched by changing the thickness of the sealant. The disadvantage of this method is that the amount of sealant is large and everywhere along the battery seal. In these areas, the sealant is not desired in large amounts because it helps the movement of water and electrolytes. Along the battery seal without the tab, it is ideal to keep the sealant as thin as possible and prevent the movement of water and electrolyte as much as possible. The heat-resistant film on the inside of the structure is used to prevent the contacts from coming into contact with the aluminum foil of the shell during the heat-sealing process. However, these membranes are also helpful for electrolyte and water movement, because they are not good barriers for water or electrolyte.

The present invention: Fen Ke can improve the sealing performance of barrier ribs and tabs without using these materials. Now, each tab of each size and thickness needs a different laminated material to match a generally perfect tab seal.

Description of the invention () • The present invention relates to improved batteries, especially improved lithium-ion and lithium polymer batteries, and improved battery cases, especially lithium-ion and lithium polymer battery cases. At present, the thickness of lithium-ion batteries is about 6.5 mm. The new housing can use thinner materials, so the battery of the present invention can be as thin as a credit card. More particularly, the present invention relates to a rechargeable battery including a first laminated board having a peripheral region and a central region, and a second laminated board having a peripheral region and a central region. The first and second laminates each have a metal foil, a polymer layer bonded to one side of the metal foil, and a hot-melt polymer coating on at least a peripheral region on the other side of the metal foil. The metal foil is preferably an aluminum foil. The hot-melt polymer coatings on the peripheral areas of the first and second laminates are sealed together. The central area of the first and second laminates constitutes a central chamber. There are anodes, cathodes and electrolytes arranged in the center chamber according to the current generation and conduction methods. Two conductive tabs are placed between the two peripheral sections. The tabs are typically aluminum, copper or nickel. One end of one of the tabs is connected to the anode, and one end of the other tab is connected to the cathode. The other ends of the two tabs protrude beyond the peripheral area of the laminate. The hot-melt polymer forms a very tight seal around the splice, which primarily prevents electrolyte leakage and water intrusion. Hot-melt polymers have significantly different physical properties than sealant polymers, and even if the two are the same or similar chemicals (polymers), they make a significant contribution to the present invention and its advantages. Compared to sealant materials, hot melt polymers have a lower viscosity at their melting points. More specifically, the present invention also relates to a battery case, which includes a first laminate layer with a peripheral region and a central region, and a paper sheet with a peripheral region and a central region.

The two laminated layers each have a metal foil, a polymer layer combined with one side of the metal foil, and a hot-melt polymer coating on at least the peripheral area on the other side of the metal foil. The metal foil is preferably an aluminum foil. The hot-melt polymer coatings on the peripheral areas of the first and second laminates are sealed together. The central areas of the first and second laminates form a central chamber. Two conductive tabs are placed between the two peripheral sections. It is made of aluminum, copper, or nickel.

Hot-melt polymer forms around the web A very tight seal 'is mainly to prevent electrolyte leakage and moisture ingress. The purpose of the present invention is not only to solve the problem of the thickness of the shell laminate and the problem of tightly sealing the tabs to prevent battery leakage and injury, but also to provide a stronger Suitable for the material of the molding process and reduce the loss of electrolyte through sealing. In the case where the molding process is not needed or desired, a thinner and cheaper laminated board can be used. In both cases, the concept of hot melt is used The tabs are tightly sealed around the edges. The material of the present invention also provides a significant pair of high thermal resistances (batteries will be exposed to high temperatures), so creating a more secure product. Printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read first Note on the back, please fill in this page again.) The present invention has the greatest sealing elasticity for different size and thickness of the different tabs by changing the amount and position of the hot-melt material. The rest of the shell can still be sealed with a minimum of sealant material. Moisture and electrolyte movement are minimized. However, to minimize thickness, size, and cost, it is more important Yes, in order to minimize the movement of electrolyte and water, the amount of hot melt must be kept to a minimum.) The purpose of hot melt is to have the greatest resistance to the electrolyte and the Chinese paper standard (CNS) A4 applies to this paper size (210X297 mm) -11-Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs 504851 A7 B7 V. Description of the invention () The electrolyte has minimal absorption or dissolution. Hot melts are selected from materials with high water barrier properties and low water solubility. When the tab and the hot melt are sealed together, in order to provide a strong bonding force with the shell, the hot melt is made of a resin of the same family as the sealant material of the laminate. Hot melt can be used in different locations and sequences of the battery pack. It can also be coated on the battery itself before or after the battery is installed in the case. The hot melt can also be applied directly to the shell material, for example, after forming the grooved shell, or after the bag-like shell is folded. < The hot melt application is performed by a gear pump unit. The hot melt is extracted from a heating tank, and then applied to a desired position through a nozzle. The principle of hot melt coating is well known to those skilled in the art of casing. As mentioned above, the hot-melt material is an organic polymer of the same family as the sealant composition of the laminate, so that the melting points of the two materials are quite close. The hot melt used therein can be applied to the case material or to the battery tabs and cooled to a solid state. When the battery is finally assembled in the case, the case is heat-sealed. The seal on the non-tab side is sealed under conventional heat, pressure and time. The parts of the housing with the tabs protruding from the seal (peripheral area) (which have been coated with hot melt) are also sealed using the same heat, pressure and time course. Hot melt uses heat and pressure to reactivate the bond with the shell material and the tabs. When melted by heat and pressure, the hot melt plugs the tab side to make the seal completely tight. The similar properties of the shell sealant and the hot melt make the heat, pressure, and time parameters used during heat sealing the same as those used for side sealing. When the seal is opened, the material is allowed to cool, and both the sealant material and the hot melt can solidify into a very strong seal. These, the seal has high mechanical strength in order to resist the battery.

Description of the invention The flow behavior of the polyamide layer outside the biaxially stretched polyamide film form helps to make it as isotropic as possible. In addition, more preferred polyamide membranes are those with a flow behavior that produces high strain hardening. High strain hardening is evidence of increased longitudinal and transverse elongation as the stress in the film increases.

The other benefits of the present invention are thinner and lighter, so The weight and size of the battery can be minimized. These materials also provide seals that are easier to bend into smaller radii than existing materials to minimize overall cell size. The sealant material and the hot-melt material may be, for example, -maleic anhydride-grafted polypropylene (a preferred polymer),-epoxy-polypropylene,-polypropylene, ·-acrylic-modified polyethylene ( Also known as E AA), a polyethylene, a polyamide, a polyester. The thickness of the sealant can be from 5 to 100 microns, more preferred is from 5 to 50 microns, and most preferred is from 5 to 20 microns. The choice of sealant focuses on materials with a melting point (blocking) that is higher than the battery exposure temperature, such as 120 ° C (for safety), and materials that resist the electrolyte at high temperatures. The choice of hot-melt polymer is also similar to that of the sealant with a chemical and melting point to facilitate sealing and plugging of the laminate side. The choice of sealant material and hot melt is to minimize electrolyte loss and water movement, both of which are factors that determine battery performance. Therefore, a thin sealant and a minimum amount of hot melt should be used to limit movement. Another important factor is that when the paper size of the existing (previous technology) laminated board is in accordance with the Chinese National Standard (CNS) A4 specification (210X297 mm) -23- (Please read the precautions on the back before filling in a copy Page) Order line 504851 Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs A7 B7_ V.

The existing sealing strength may be as follows, for example: Prior art: The present invention: 6 to 15N / 15mm > 10 to 20N / 15mm So, typically, the sealing strength has been increased by 200%. It is also important that the seal strength is a function of the temperature used. Seals must not fail under thermal and mechanical stress. Therefore, the choice of sealant material is very important. In addition to its chemical resistance, the sealant must also provide high thermal-mechanical resistance. The selection of the sealant in the present invention focuses on materials with a melting point higher than the maximum exposure temperature of the battery. From a testing point of view, the maximum battery exposure temperature is 120 ° C and above. Long-term tests are usually performed at 60 ° C for at least 30 days and at 85 ° C for 4 days. At this temperature, it is important that there is no leakage and minimal electrolyte loss through the seal. Therefore, the sealant is selected to have a melting point higher than the maximum temperature at which the battery is exposed, that is, higher than 120 ° C. A selected system includes a thin lacquer coating on the laminated board: The present invention · The print of the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs——I — — · _ (Please read the notes on the back first # Fill this tribute) -01.

The thickness of the material of the present invention can be half of the existing material, most of which are due to the application of the Chinese National Standard (CNS) A4 specification (210X297 mm) to this paper size. B7 V. Description of the invention () To avoid the use of a large amount of sealant material in the laminated board to seal the ^ # area, and not use a heat-resistant film, such as polyethylene terephthalate or oriented polyamine. Example 1 One formable laminated board structure of the present invention: Polyurethane film, 25 micron urethane adhesive aluminum foil, 45 micron polypropylene coating, 6 micron The present invention can be made into the same shape as the existing material, that is, made Depth 45 mm and almost flat wall (4-degree angle, as with existing materials). After forming, the sealing of the electrolyte at high temperature is as follows, and the filled electrolyte and sealed shell are exposed to 60 for 30 days: Prior art 2 The present invention: 22 to 105 mg, depending on the structure 1 · 8 Numbers above 3.0 mg indicate the amount of electrolyte that passed the seal within 30 days. Therefore, the present invention is at least seven times tighter than existing materials and is more resistant to electrolyte migration. The splice area is sealed with a hot melt, which is also part of the invention. The hot melt compensates for differences in thickness around the tabs, depending on the battery, which can typically be 20 to 100 microns thick. The hot melt of polyamide, polyester or polyolefin (preferred is polypropylene-based) is applied on the laminate of the present invention or on the tab itself to completely plug the tab side to provide a complete Tightly sealed. At the same time, the hot melt protects the tabs from contact with the aluminum foil of the case, thus avoiding short circuit of the battery.

Description of the invention () helps In the heat sealing process. The hot melt and sealant of the laminated board of the present invention are sealed together with the tabs, and the rest of the peripheral area is sealed at the same time under the same temperature, pressure and residence time conditions. The melting point of the polyethylene sealant used in the present invention is 15 ° C and the melting point of the hot melt is 156 ° C, which makes the two materials have a perfect combination during heat sealing. When using existing materials, it is very difficult to keep the tabs tight to prevent the electrolyte from moving for long periods of time. As described above, the same parallel test was performed with a molded electrolyte-filled hermetically sealed case, in which case the two tabs were performed in an existing material and a material of the present invention having a hot melt. The choice of splice material is aluminum, 50 micrometers thick. The sealed enclosure was exposed to 60 T for 20 days, and the electrolyte loss was recorded: Existing materials with sealed tabs: Materials of the present invention with sealed tabs 111 to 736 mg 12 to 21 mg (depending on structure) The above data Explain the amount of electrolyte loss after 20 days through the seal (including the seal tab and its surrounding area). Therefore, it is obvious that the material of the present invention, together with the concept of the hot melt of the sealing tab of the present invention, is at least 5 times higher than the performance of the existing system. The present invention can also provide a further reduction in electrolyte loss. In addition to these significant performance improvements in battery protection, the laminates of the present invention are typically 25% lighter than existing materials. At the same time, for formable structures, the materials of the present invention are typically 40% thinner than existing materials. Moreover, changing the amount of hot melt can accommodate different sizes and thicknesses.

Description of the invention () film, the amount of this hot melt is used to condense on the splice. This can be done without modifying the laminate of the present invention. Conversely, when using existing materials, the sealant layer must be changed to accommodate thicker or thinner tabs. Therefore, the right tab is 80 microns thick, not 50 microns. The thickness of the sealant material in the existing laminate is almost doubled to provide a tight tab seal. This will also impact the total movement of electrolyte and water through the seal, because the thicker the seal, the greater the electrolyte and water movement path. In addition, structural costs will increase. In addition, the side seals that need to be folded will also be thicker and take up more space, making it more difficult to fold. This is due to the size of the existing laminates. The present invention overcomes all these shortcomings by applying a suitable amount of hot melt to the tab sealing area without harming any side seals. The movement is always kept to a minimum and the side-folded folds are not affected at all. The sealing area which must then be folded consists of two layers of the material according to the invention or an existing material. Therefore, the sealing thickness of the present invention is also 40% thinner, which reduces the space (volume) required for the folding seal. In addition, compared with existing materials, the material of the present invention has a uniquely improved full-fold property. This makes the folding process surprisingly easy, which is another advantage of the present invention. If molding is not desired, a thinner laminate based on one of the present invention can be used: polyester or polyamide film, 9 to 12 micron urethane adhesive aluminum foil, 10 to 25 micron polypropylene coating, 3 to 6 Microns.

Hot melt is also used to seal and plug the metal tabs with the laminate of the present invention to provide a completely tight seal. It is technically known to make a fin seal, that is, from a complete point of view, the two ends where the fin seal and the end seal are combined are the most important. In addition to the tab area, the present invention also applies hot melt to the joints of the fin seal and the end seal.
