Description of the invention (1) [Technical field] ----------- install --- (please read the precautions on the back before filling this page) This invention is about a kind of A packaging material for a polymer battery having moisture resistance, content resistance, and moldability, and a solid organic electrolyte (polymer electrolyte), and a method for manufacturing the same. [Technical Background] Polymer batteries, also commonly referred to as lithium batteries, are batteries that have a polymer polymer electrolyte and generate current based on the flow of lithium electrons. The anode and cathode active materials are made of polymer polymers. Constituted by. The content of the lithium battery is composed of anode current collecting material (aluminum, nickel) / anode active material layer (metal oxide, carbon black, metal sulfide, electrolyte, polyacrylonitrile and other cylindrical molecular anode materials) / electrolyte Layer (consisting of inorganic solid electrolyte and colloidal electrolyte composed of lithium salt of carbonate-based electrolyte such as propylene carbonate, ethylene carbonate, dimethyl carbonate, and methyl methyl carbonate) / cathode active material layer (lithium metal, alloy , Carbon, electrolyte, polymer cathode materials such as polyacrylonitrile) / cathode current collector materials (copper, nickel, stainless steel) and packaging materials. The use of polymer batteries printed by employees' cooperatives in the Intellectual Property Bureau of the Ministry of Economic Affairs, such as computers, portable terminal devices (mobile phones, PDAs, etc.), camcorders, electric vehicles, energy storage batteries, robots, satellites, etc. . Also, the packaging body of the polymer battery in the U.K. uses a metal can that is formed into a cylindrical shape or a rectangular shape by container pressurization, or a container made of a base material layer / aluminum / seal tape. For bag-shaped objects obtained from multi-layer films, the paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) 521035 A7 B7 V. Description of the invention (2) However, the packaging of polymer batteries generally occurs as follows problem. In the case of a metal can, the outer wall of the container is a rigid outer wall, so it can be determined by the shape of the battery body. Therefore, the outer wall of the container is designed to cooperate with the battery body, so the size of the hard case used by the battery body is determined by the battery, so the freedom of shape is extremely low. · Therefore, the laminate has been developed into a bag shape. In the form of a pouch for placing the battery body, or the former laminate is press-molded into a recess, and a battery groove can be placed in the recess. Comparing the creasing form with the pouch form, a more compact packaging form can be obtained. However, no matter what kind of packaging body, it must not lack the strength, insulation, etc. of the moisture resistance or puncture resistance required for the packaging body of polymer batteries. Therefore, in the form of grooves, the laminate used The suitability for press forming is extremely important. For example, a packaging material for a polymer battery in the form of a groove, specifically, for example, a laminated layer composed of nylon, an adhesive layer, aluminum, an adhesive layer, and cast polypropylene. However, even if the adhesive layer described above uses a dry layer with excellent adhesive strength, in the case of indentation molding, when the polymer battery is placed in a packaging material and the peripheral portion is heat-sealed, the resistance Delamination occurs between the ridge and the aluminum. In addition, the hydrogen fluoride produced by the reaction of the electrolyte components of the polymer battery with moisture can cause delamination between aluminum and cast polypropylene. [Contents of the invention] The purpose of the present invention is to provide a polymer battery package which can provide protection to polymer batteries, and also has excellent processing moldability. The paper size is applicable to Chinese National Standard (CNS) A4 specifications ( 210 X 297 mm) (Please read the notes on the back before filling out this page) Installed by the Intellectual Property Bureau of the Ministry of Economic Affairs and printed by the Consumer Cooperatives 521035 A7

Inorganic solid electrolytes composed of lithium salts of carbonate-based electrolytes such as dimethyl carbonate, ethylene methyl carbonate, and colloidal electrolytes / cathode active material layers (lithium metal, alloy, carbon, electrolyte, polyacrylonitrile, etc. Polymer cathode material) / cathode current collector material (copper, nickel, stainless steel). As shown in Figs. 2 (b) and 2 (c), the package body 5 does not need to cover the package cover 5t, and the two packages 5a can be overlapped and sealed by heat sealing around them. (Fig. 2 (b)), or only three sides can be heat-sealed (Fig. 2 (c)). At this time, as shown in FIG. 2 (e), it is preferable that the side wall portion 8 of the package body 5a after molding is as upright as possible, and the polymer battery body 2 can be placed tightly. The compound needs to have excellent ductility during press molding, that is, moldability is an essential factor. Laminates of packaging materials, such as nylon / adhesive layer / aluminum / adhesive layer / cast polypropylene. If the adhesive layer is prepared by dry layer method, the aluminum in the side wall of the antecedent is used in press molding. Delamination is extremely likely to occur between the substrate and the substrate. In addition, if the polymer battery body is placed in a packaging body, it is also prone to be delaminated in the portion where the polymer battery is heat-sealed around. In addition, the hydrofluoric acid produced by the reaction of the electrolyte and moisture as a constituent element of the battery will erode the inner surface of the incision and cause delamination.

Description of the invention (14) The base material 6 1 can be used in dry layer, extruded layer, or other methods with aluminum 6 2 forms a laminated layer. The barrier layer (aluminum) 6 2 in the packaging material for a polymer battery of the present invention is a layer for preventing water vapor and the like from penetrating into the polymer battery from the outside, so that the barrier layer 6 2 is a sand hole, and Processing suitability (small. Stability of bagging and groove forming), and in order to increase porosity of iron sand, generally, metals with a thickness of more than 15 // m, such as aluminum, nickel, or inorganic compounds, such as silicon oxide, aluminum oxide, etc. As the vapor-deposited film or the like, the barrier layer 62 is preferably, for example, 20 to 80 // m of aluminum. In order to further improve the occurrence of sand holes, in order to avoid cracks in the grooved part when the polymer battery packaging body is formed by using a mold for indentation, the inventors have adopted the aluminum material used for the barrier layer 62 as an example. The iron content is 0. 3 ~ 9. ◦% by weight, preferably 0. 7 ~ 2. In the range of 0% by weight, compared with aluminum without iron, aluminum has better ductility, and does not cause sand holes due to folding when used as a laminate. In addition, it is also used when forming grooves by forming grooves. It is easier to form the side wall portion. If the previous iron content is less than 0. At 3% by weight, the occurrence of sand holes cannot be prevented, and there is no problem that can improve the formability of the pressure groove. In addition, the iron content of the foregoing aluminum exceeds 9. At 0% by weight, the flexibility of aluminum is hindered, and the bag-making properties of the laminate are deteriorated. In addition, the aluminum produced by the cold rolling method will change its softness and flexibility due to different calcination treatment conditions.

Description of the invention (28) If the iron content in the previous note is lower than 0.3 ° /. In this case, it is not possible to prevent the occurrence of sand holes and to improve the formability of the grooves. In addition, when the iron content of the foregoing aluminum exceeds 9.0%, the flexibility of the aluminum is hindered, and the bag-making property of the laminate is deteriorated. . Also, the aluminum produced by the cold rolling method will be due to the calcination processing conditions. The softness and flexibility are changed by the difference. Among the aluminum used in this example, compared with the hardened product obtained without calcination treatment, the aluminum obtained by proper calcination or complete calcination treatment has softness. Aluminum is preferred. Foreword, for the combination of softness, flexural strength, and hardness, that is, the calcination conditions, it can be appropriately selected according to the required processing suitability (small bag properties, groove forming). For example, in order to prevent wrinkles or pits during molding, it is better to use soft aluminum in accordance with the degree of molding. For the purpose of the present invention, the inventors have learned through in-depth investigations that if the aluminum surface of the barrier layer 12 of the packaging material for polymer batteries is coated with the surface treatment layers 15a, 15b, A laminate which can satisfy the packaging materials described above can be obtained. The surface treatment mentioned above, specifically, for example, those who use acid-resistant coatings such as phosphate, chromate, fluoride, and triazine thiol compounds. In this way, in addition to preventing the separation between aluminum and the substrate layer during the groove forming process, Prevent the hydrogen fluoride produced by the reaction of electrolyte and moisture in polymer batteries, dissolve the aluminum surface, rot uranium, etc., especially prevent the alumina existing on the aluminum surface from dissolving, rot uranium, and improve the adhesion of aluminum surface (wetting) It can also prevent the delamination between the substrate layer and aluminum during the groove forming and heat sealing, and prevent the hydrogen fluoride produced by the reaction between the electrolyte and the water from delaminating on the inner surface side of the aluminum.

Description of the invention (29) The results of surface treatment of aluminum surface using various substances, and the acid resistance of the former note Among the sexual film-forming materials, a phosphoric acid plating treatment using a composition consisting of a phenol resin, a chromium fluoride (3) compound, and a phosphoric acid component is also preferred. The surface treatment of the previous note is if the packaging body of the polymer battery is in the shape of a pouch. In the formula, it is only necessary to use aluminum as the innermost surface. When the packaging body of the polymer battery is in the form of an indentation groove, surface treatment layers 1 5 a and 1 5 b can be formed on both sides of aluminum to prevent delamination between the aluminum and the substrate layer when the indentation groove is formed. Further, a laminate having a surface treatment on both sides of aluminum can also be used in the form of a pouch. As described above, using the manufacturing method of the packaging material for a polymer battery of the present invention, the heat-sealable layer 14 or the adhesive resin layer 1 3 laminated with the heat-sealable layer may be a polyethylene resin. If a sandwich laminate of a polyethylene film is produced by extrusion molding with a polyethylene resin or acid-denatured polyethylene as the adhesive resin 13 on the surface treatment surface 1 5 b of the previous note, the polyethylene resin on the surface treatment surface side adheres. Poor performance, even when it is an extruded acid-denatured polyethylene resin, its adhesion is not good. In this regard, the present inventors applied an emulsion of acid-denatured polyethylene on the surface treatment surface 1 5 b of the previous note by a roller coating method, etc., and dried it at 170 ° C to 2 ° C. After calcination at a temperature of 0 0 ° C, the aforementioned acid-denatured polyethylene is formed into a sandwich laminate in the form of an adhesive resin 15 b. Although the adhesive strength can be improved, the calcination processing speed is extremely slow, so the adhesive resin layer is adhered. The productivity is also extremely poor. And the inventors, for the coating and calcination of acid-denatured polyethylene, the Chinese national standard (CNS) A4 specification (210 X 297 mm) is applicable. ----- IIIII------ -I ^ «— — — — — — I—.

Description of the invention (45) (Please read the back first Please note this page and fill in this page again) The iron content is 0.3 ~ 9 · 〇%, preferably 0.7 ~ 2.0% 0% IS 0 force formula 'When compared with aluminum without iron, It has good ductility, and it does not cause sand holes due to folding when it is laminated. In addition, it is easier to form side walls in the form of grooves when it is formed into a package. If the iron content is less than 0. At 3%, no defense is generated. It can prevent the occurrence of sand and L, and improve the formability of pressure grooves. When the iron content of aluminum mentioned above exceeds 9.0%, the flexibility of aluminum is hindered, and the bag-making properties of the laminate are deteriorated. Also, 'the aluminum produced by the cold rolling method will change its softness and flexibility due to the different calcination treatment conditions, and the aluminum used in this example' is more than the hardened product obtained without the calcination treatment. From the standpoint of preference, aluminum having a softening tendency obtained by appropriate calcination or complete calcination is preferred. Foreword, for the combination of softness, flexural strength, and hardness, that is, the calcination conditions, it can be appropriately selected according to the required processing suitability (small bag properties, groove forming). For example, in order to prevent wrinkles or pits during molding, it is better to use soft aluminum in accordance with the degree of molding. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs The inventors have prevented the hydrogen fluoride (HF) generated by the reaction of the electrolyte and moisture of the polymer battery with dissolution and corrosion on the side surface of the aluminum polymer battery body 2 In particular, it prevents the alumina present on the aluminum surface from dissolving and corroding, and can improve the adhesion (wetting) of the two surfaces of the Ming, and improve the stability of the adhesion between the aluminum and the adhesive resin layer when the laminate is formed For purposes such as chemical conversion, the present invention can obtain significant effects by forming an acid-resistant coating on the aluminum surface and the inside, and improving the adhesion.

By. Since the innermost resin layers 14 and 14 need to have heat-sealability, it is preferable to use cast polypropylene (hereinafter, abbreviated as c P P) having necessary physical properties such as heat resistance, moisture resistance, and press moldability. Subsequently, using the surface treatment surface of aluminum has. The more adhesive acid-denatured P P and C P P are co-extruded to form a laminate in which the acid-denatured p p layer described above is located on the aluminum side.

Therefore, in order to stabilize the sand pores of the barrier layer monomer and the stability of the mouthability X (small bag, groove forming), and to increase the sand pore resistance, aluminum and nickel with a thickness of more than 15 // m are used. Other metals, or inorganic; compounds, such as silica, alumina, are better steamed. The barrier layer is better in China National Standard (CNS) A4 specification (210 X 297 mm) ----- I--I--installation *-I ---- order ---- I --- · ( Please read the Zhuyin on the back?

To further improve the occurrence of sand holes, the form of the polymer battery package body is not formed when the groove is formed. For the material of aluminum as a barrier layer, the iron content should be in the range of 0.3 ~ 9 · 0%, preferably 0 · 7 ~ 2 · 0%. In comparison, aluminum has better ductility, and does not cause sand holes due to folding when used as a laminate. In addition, it is easier to form side walls in the form of grooves when forming grooves to form packages. If the content of iron in the foregoing is less than 0.3%, the occurrence of sand holes cannot be prevented, and the formability of the indentation cannot be improved. Moreover, when the content of iron in the foregoing is more than 9%, the flexibility of aluminum is hindered. , And the bag-making property of the laminate is deteriorated. In addition, the aluminum produced by the cold rolling method will change its softness and flexibility due to the different calcination treatment conditions. Among the aluminum used in this embodiment, the harder processed material is obtained without the calcination treatment. From the standpoint of preference, aluminum having a softening tendency obtained by appropriate calcination or complete calcination is preferred. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. For the combination of softness, flexural strength, and hardness, that is, the calcination conditions, appropriate selection can be made according to the processing suitability (small bag properties, groove forming). For example, in order to prevent wrinkles or pits during molding, it is better to use soft aluminum in accordance with the degree of molding. For the purpose of the present invention, the inventors have thoroughly studied the results, and learned that the surface and inside of the barrier layer 12 of the packaging layer for polymer battery 12 are treated with the surface layer to achieve the aforementioned packaging material. Desired laminate. The surface treatment of the former, specifically for example, phosphate, chromate-60-This paper size is applicable to Chinese National Standard (CNS) A4 (210 X 297 mm) Printed by the Intellectual Property Bureau Staff Consumer Cooperative of the Ministry of Economic Affairs 521035 A7 ___ B7 V. Description of the invention (58), acid-resistant film formed by fluoride, triazine thiol compound, etc., this can prevent the separation between aluminum and the substrate layer during the molding of the groove, and also prevent the electrolyte of the polymer battery Hydrogen fluoride produced by reaction with water, dissolves and corrodes aluminum surface, especially prevents oxidation and bromide existing on the surface of brocade from dissolving and corroding, and can improve the adhesion (wetting) of aluminum surface. It can also prevent pressure The delamination between the substrate layer and the aluminum when the tank is formed and heat-sealed, and the delamination on the inner side of the aluminum caused by the hydrogen fluoride generated by the electrolyte and water. After using various substances to surface-treat the aluminum surface and further study its effects, it was found that among the above-mentioned acid-resistant film-forming substances, three components including phenol resin, chromium fluoride (3) compound, and phosphoric acid were used. The composition of the aqueous solution is preferably a phosphoric acid plating treatment. If the surface treatment of the former is in the form of a pouch of a polymer battery, only the innermost resin layer side of aluminum need be treated. When the package body of the polymer battery is in the form of an indentation, surface treatment can be performed on both sides of the aluminum 12 to prevent delamination between the aluminum 12 and the substrate layer 11 during the indentation molding. Further, a laminate having surface treatment on both sides of aluminum can also be used in the form of a pouch. If the surface treated surface of the preface is extruded with acid-denatured resin PP as the adhesive resin layer 13 and formed into a sandwich laminate with the innermost resin layer 14 of CPP, the acid extruded on the surface treated surface will be caused. The viscosity of denatured P p resin deteriorated.

'The inventors The material of aluminum as the barrier layer is such that the iron content is in the range of 0.3 to 9%, preferably 0 to 7 to 2.0%. When compared with aluminum without iron, aluminum It has better ductility, and does not cause sand holes due to folding when used as a laminate. In addition, it is easier to form side walls in the form of grooves when forming grooves to form packages. If the content of iron in the foregoing is less than 0.3%, the prevention of the occurrence of sand holes and the improvement of the formability of the indentation cannot be achieved. In addition, when the content of iron in the foregoing aluminum exceeds 9.0%, the flexibility of the aluminum is hindered. , And the bag-making property of the laminate is deteriorated.

After using various substances to surface-treat the aluminum surface and further study its effects, it was found that among the above-mentioned acid-resistant film-forming substances, three components including phenol resin, chromium fluoride (3) compound, and phosphoric acid were used. The composition of the aqueous solution is preferably a phosphoric acid plating treatment. If the surface treatment of the former is in the form of a pouch of a polymer battery, only the innermost resin layer 14 of aluminum 12 needs to be processed. When the package body of the polymer battery is in the form of a groove, the surface treatment can be performed on both sides of aluminum to prevent the aluminum from forming when the groove is formed. 1 2 This paper applies Chinese national standard (CNS) A4 specifications (210 X 297 mm) --------- I--install -------- order ------- I »^ _w— (Please read the notes on the back before filling in this Page) Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, Consumer Cooperatives This paper is printed in accordance with Chinese National Standard (CNS) A4 (210 X 297 public love) 521035 A7 --____ B7 V.

Description of the invention (97) (Please first Read the precautions on the back and fill in this page.) When compared with the method of aluminum without iron, aluminum has better ductility, and it will not cause sand holes due to folding when used as a laminate. It is also easier to form a side wall portion in the form of a groove when forming to form a package. If the content of iron in the foregoing is less than 0.3%, it will fail to prevent the occurrence of sand holes and improve the formability of the grooves. In addition, when the content of iron in the foregoing aluminum exceeds 9 · 0%, the aluminum will be hindered. The softness deteriorates the bag-making property of the laminate. In addition, the aluminum produced by the cold rolling method will change its softness and flexibility due to the different calcination treatment conditions. Among the aluminum used in this embodiment, the harder processed material is obtained without the calcination treatment. From the standpoint of preference, aluminum having a softening tendency obtained by appropriate calcination or complete calcination is preferred. Foreword, the combination of softness, flexural strength, and hardness of aluminum, that is, the calcination conditions, can be appropriately selected according to the required processing suitability (small bag property, groove forming). For example, in order to prevent creasing or sanding when forming the groove, it is better to use soft aluminum in accordance with the degree of molding.

In the present invention, the base material layer 11 may be made of an extended polyester or a nylon film. In this case, the polyester resin is, for example, polyethylene terephthalate, polybutylene terephthalate, poly Vinylnaphthyl ester, polybutylnaphthyl ester, copolymerized polyester, polycarbonate, etc. Examples of the nylon resin include polyamide resins, that is, nylon 6, nylon 6,6, nylon 6,6 and nylon 6, copolymers, nylon 6,10, MXD6, and the like. The base material layer 1 1 mentioned above, if it is used as a polymer battery, because it is printed by the consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs and directly contacts the external hardware, so it is basically a resin layer with insulation properties. good.

Description of the invention (11Q) (Please read the notes on the back before filling this page) Workability (small bag) , Molding stability), and in order to increase the pore resistance of sand, it is better to use aluminum, nickel and other metals, or inorganic compounds, such as silicon oxide and aluminum oxide, with a thickness of 15 / m or more. The barrier layer is preferably aluminum having a thickness of, for example, 20 to 8 0 // m. In order to further improve the occurrence of sand holes, in the form of the package body of the polymer battery, when forming grooves, in order to avoid cracks in the grooves, the inventors have made the material of aluminum as a barrier layer so that Its iron content is 0.3 ~ 9.0%, preferably 0.7 ~ 2.0%. Compared with aluminum without iron, aluminum has better ductility, and it will not be caused by folding when it is a laminate. The sand hole phenomenon, in addition, it is easier to form a side wall portion in the form of a groove when the groove is formed to form a package. If the content of iron in the foregoing is less than 0.3%, the occurrence of sand holes cannot be prevented, and the formability of the indentation cannot be improved. Moreover, when the content of iron in the foregoing is more than 9%, the flexibility of aluminum is hindered. , And the bag-making property of the laminate is deteriorated. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the aluminum produced by the cold rolling method will change its softness and flexibility due to different calcination processing conditions. Among the aluminum used in this embodiment, Compared with the hard processed material obtained without the calcination treatment, the softened aluminum obtained by the appropriate calcination or the complete calcination treatment is preferred. Foreword, the combination of softness, flexural strength, and hardness of aluminum, that is, the calcination conditions, can be appropriately selected according to the required processing suitability (small bag property, groove forming). For example, in order to prevent wrinkles or sand holes during the forming process, it is better to use soft aluminum in accordance with the degree of molding. For the purpose of the present invention, the inventors have thoroughly studied and found that the paper size is applicable to the Chinese National Standard (CNS) A4 (210 X 297 mm) 521035 A7 B7 V.

The surface treatment of the foregoing, specifically, for example, an acid-resistant film formed of phosphate, chromate, fluoride, triazine thiol compound, etc., so as to prevent delamination between the aluminum and the substrate layer during the molding of the groove, and It can prevent the hydrogen fluoride produced by the reaction between electrolyte and moisture of polymer batteries, dissolve and corrode aluminum surface, especially prevent the alumina existing on the aluminum surface from dissolving and corroding, and can improve the adhesion (humidity) of aluminum surface ), Can also prevent the delamination between the substrate layer and aluminum during the groove forming and heat sealing, and the aluminum inner side separation caused by the hydrogen fluoride generated by the electrolyte and moisture. After using various substances to surface-treat the inner surface of aluminum and further study its effects, it was found that among the aforementioned acid-resistant film-forming materials, phenol resin, chromium fluoride (3) compound, phosphoric acid, etc. were used. The aqueous solution composed of the components is preferably a phosphoric acid plating treatment. If the surface treatment of the former is in the form of a pouch of a polymer battery, only the innermost resin layer 14 of aluminum 12 needs to be processed. When the package body of the polymer battery printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs is in the form of grooves, surface treatment can be performed on both sides of aluminum 1 2 to prevent aluminum 1 2 and substrates from forming when the grooves are formed. Delamination occurs between the material layers 11. Further, a laminate having surface treatment on both sides of aluminum 12 can also be used in the form of a pouch.

Description of the invention (124) / Extended Nylon (7) acrylic resin / Extended Nylon (acrylic resin is a film-like substance 'or the liquid coating layer is dried Those formed later) The former barrier layer 12 is a layer to prevent the intrusion of water vapor from the outside to the inside of the polymer battery in particular, so that the pores of the barrier layer alone and the processing suitability (small bag, groove forming) In order to increase the stability of sand pores, it is better to use metals such as aluminum and nickel with a thickness of more than 15 // m, or inorganic compounds such as silicon oxide and aluminum oxide for vapor deposition. The barrier layer is preferably a brocade having a thickness of, for example, 20 to 8 0 // m. In order to further improve the occurrence of sand holes, in the form of the package body of the polymer battery, when forming grooves, in order to avoid cracks in the grooves, the inventors have made the material of aluminum as a barrier layer so that Its iron content is in the range of 0 · 3 ~ 9 · 0% by weight, preferably in the range of 0 · 7 ~ 2 · 0% by weight. Compared with aluminum without iron, aluminum has better ductility 'as a layer When merging, it will not cause sand holes due to folding. In addition, it is easier to form side walls in the form of grooves when forming grooves to form packages. If the iron content is less than 0.3% by weight, the occurrence of sand holes cannot be prevented, and the formability of the indentation cannot be improved. When the iron content of the foregoing aluminum exceeds 9.0% by weight, the aluminum content will be hindered. The softness deteriorates the bag-making property of the laminate. In addition, the aluminum produced by the cold rolling method will change its softness and flexibility due to the different calcination treatment conditions. Among the aluminum used in this embodiment, the harder processed material is obtained without the calcination treatment. From the standpoint of preference, aluminum having a softening tendency obtained by appropriate calcination or complete calcination is preferred. This paper size applies to Chinese National Standard (CNS) A4 (210 X 297 mm) -127 ^ I ----— 丨 丨 丨 ------ 丨 丨 Order ------ I (Please Read the precautions on the back before filling this page) 521035 Α7 Β7 12β V. Description of the invention () (Please read the precautions on the back before filling this page) Foreword, for the combination of softness, flexural strength and hardness of aluminum That is, the calcining conditions can be appropriately selected according to the required processing suitability (small bag properties, pressure groove forming). For example, in order to prevent wrinkles or sand holes during the forming process, it is better to use soft aluminum in accordance with the degree of molding. For the purpose of the present invention, the inventors have thoroughly studied the results, and learned that the surface and inside of the barrier layer 12 of the packaging layer for polymer battery 12 are treated with the surface layer to achieve the aforementioned packaging material. Desired laminate. The surface treatment of the foregoing, specifically, for example, an acid-resistant film formed of phosphate, chromate, fluoride, triazine thiol compound, etc., so as to prevent delamination between the aluminum and the substrate layer during the molding of the groove, and It can prevent the hydrogen fluoride produced by the reaction between electrolyte and moisture of polymer batteries, dissolve and corrode aluminum surface, especially prevent the alumina existing on the aluminum surface from dissolving and corroding, and can improve the adhesion (humidity) of aluminum surface ), Can also prevent the delamination between the substrate layer and aluminum during the groove forming and heat sealing, and the aluminum inner side separation caused by the hydrogen fluoride generated by the electrolyte and moisture. Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the inner surface of aluminum is surface-treated with various substances, and the effect is studied in depth. It is found that among the acid-resistant film-forming substances mentioned above, phenol resin, fluorine An aqueous solution composed of three components, such as a chromium (3) compound and phosphoric acid, is preferably treated with a phosphate rock. If the surface treatment of the former is in the form of a pouch of a polymer battery, only one side of the innermost resin layer side of the aluminum 12 needs to be processed. When the package body of the polymer battery is in the form of an indentation, surface treatment can be performed on both sides of the aluminum 12 to prevent delamination between the aluminum 12 and the substrate layer 11 during the indentation molding. In addition, the dimensions of this paper on both sides of aluminum 1 2 are in accordance with Chinese National Standard (CNS) A4 specifications (210 X 297 mm) 128 ^ 521035 A7---"B7 V.

The inventors have studied the results of the lamination method that shows stable adhesive strength, and learned that the substrate Layer 1 1 is dry-laminated with the surface-treated barrier layer 12 on both sides. The side 1 5 a is dry-laminated, and the other side 1 5 b of the barrier layer 12 is acid-denatured pp as the adhesive resin 丄 3 and acid-denatured polymer. After extruding propylene, co-extrusion with an ethylene-rich random polypropylene film of the innermost resin layer 14 to obtain a laminate 10, and heating the laminate 10 to the previously mentioned adhesive resin 1 Under conditions above the softening point of 3 ', a laminate with a specific strength can be obtained. That is, a specific method of heating sH', such as a method of contacting with a hot roller, hot air, near or far infrared, etc., the present invention can use any A heating method, as long as it can be heated to achieve the aforementioned adhesion The temperature above the softening point of the resin may be sufficient. In another method, for example, when co-extrusion lamination is performed, the surface temperature of the innermost resin layer 14 of aluminum 12 is heated to a temperature above the softening point of the acid-denatured polypropylene resin. At the temperature, a laminate with stable adhesive strength can be obtained. The ethylene-rich random polypropylene used in the innermost resin layer 14 printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs has an ethylene content of 5 ~ 1 Omo 1%, preferably in the range of 6 ~ 8mo 1%.

Description of the invention (127) Generally, when compared with random propylene, the resin is softer, so the slip is poor. To solve this problem, you can use the inner resin Layer 1 An anti-blocking agent (hereinafter referred to as AB agent) is added to 4. The amount of the AB agent is preferably from 0.1 to 2.0% by weight for the resin layer to be added. The innermost resin layer 14 is a multilayer 14a. When 14b, AB agent can be added to the layer forming the adhesive surface. When AB agent is added to the innermost resin layer 14, the sliding coefficient can be improved due to the reduction of the friction coefficient on the surface of the adhesive layer, which can be used for polymer batteries. The secondary processing of packaging materials is more effective in bag making and grooving processing. The added AB agent is an inorganic sliding material such as silicon and zeolite with an average particle size of 1 5 // m (/) or less, and acrylic resin. Organic sliding materials such as resin particles obtained from polyester resins are preferred.

Sex has a significant stabilization effect. In addition, the surface treatment results are applied to both sides of aluminum, which can prevent delamination between the substrate layer and aluminum during the groove molding and heat sealing, and can prevent the reaction between the electrolyte and moisture of the polymer battery. The generated hydrogen fluoride corrodes the aluminum surface, so it is also very effective in preventing the separation between the aluminum and the side surface of the content. In addition, because the ethylene-rich random polypropylene film in the innermost resin layer uses acid-denatured PP as an adhesive resin and is laminated with a co-extrusion layer, it has excellent productivity and is subjected to post-heat treatment.

Description of the invention (14 ()) (Please read the notes on the back before filling this page) At the same time, when the polymer battery package used for secondary processing is molded using a groove, the substrate layer 11 is multilayered in order to reduce the frictional resistance between the mold and the substrate layer during the groove molding. Alternatively, the surface of the base material layer 11 is preferably provided with a fluorine-based resin layer, an acrylic resin layer, a polysiloxane resin layer, or the like. For example, the base material layer 11 may have the following constitutional content.

Description of the invention (141) (Please read the notes on the back before filling this page) Cracks, the inventors have made the material of the aluminum 12 as the barrier layer 12 to make it When the iron content is in the range of 0.3 to 9.0% by weight, preferably 0.7 to 2.0% by weight, aluminum has better ductility when compared with aluminum without iron, and it is not caused by folding when it is used as a laminate. A sand hole phenomenon occurs, and in addition, it is easier to form a side wall portion in the form of a groove when the groove is formed to form a package. If the foregoing iron content is less than 0.3% by weight / 0, the occurrence of sand holes cannot be prevented, and the molding performance of the indentation cannot be improved. Furthermore, if the foregoing aluminum content exceeds 9 · 0% by weight, it will impede. The softness of aluminum deteriorates the bag-making properties of the laminate. In addition, the aluminum produced by the cold rolling method will change its softness and flexibility due to the different calcination treatment conditions. Among the aluminum used in this embodiment, the harder processed material is obtained without the calcination treatment. From the standpoint of preference, aluminum having a softening tendency obtained by appropriate calcination or complete calcination is preferred. Foreword 'For the combination of aluminum's flexibility, flexural strength, and hardness, that is, the calcination conditions, it can be appropriately selected according to the required processing suitability (small bag property, groove forming). For example, in order to prevent wrinkles or sand holes during the forming process, it is better to use soft aluminum in accordance with the degree of molding. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. For the purpose of the present invention, the inventors learned that the surface and the inside of the aluminum layer of the barrier layer 12 of the packaging material for polymer batteries are also investigated.

Explanation of the invention (142) Dissolution, rotten uranium, etc., in particular to prevent the alumina existing on the aluminum surface from dissolving and corroding, and to improve the adhesion (wetting) of the aluminum surface, and also prevent pressure The delamination between the substrate layer and the aluminum when the tank is formed and heat-sealed, and the delamination on the inner side of the aluminum caused by the hydrogen fluoride generated by the electrolyte and water. After using various substances to surface-treat the inner surface of aluminum and further study its effects, it was found that among the aforementioned acid-resistant film-forming materials, phenol resin, chromium fluoride (3) compound, phosphoric acid, etc. were used. The aqueous solution composed of the components is preferably a phosphoric acid plating treatment. If the surface treatment of the former is in the form of a pouch of a polymer battery, it is only necessary to perform single-sided treatment on the innermost resin layer 14 of aluminum 12. When the package body of the polymer battery is in the form of an indentation, surface treatment can be performed on both sides of the aluminum 12 to prevent delamination between the aluminum 12 and the substrate layer 11 during the indentation molding. Furthermore, a laminate with surface treatment on both sides of aluminum 2 can also be used in the form of a pouch. The present inventors conducted in-depth research on a lamination method that can exhibit stable adhesive strength, and found that the base layer 11 and the side surfaces of the barrier layer 12 and the side surfaces 15a treated with the surface layer were dried.

Description of invention (143) 'As long as it can be heated to above the softening point of the aforementioned adhesive resin Just the temperature. In other methods, for example, when sandwiching, the surface temperature of the innermost resin layer 14 of aluminum 12 is heated to a temperature above the softening point of the acid-denatured polypropylene resin to obtain stable adhesive strength. Of the laminate. The ethylene-rich random polypropylene used in the innermost resin layer 14 has an ethylene content in the range of 5 to 10 mol 0/0, preferably 6 to 8 mol 0/0. As described above, the present inventors have used the ERRP as the innermost resin layer 14 of the packaging material for polymer batteries, thereby preventing the package body from being whitened or cracked during the formation of the pouch or the groove. In the present invention, the ERRP used in the innermost resin layer 14 is inferior in sliding properties because the resin is softer when compared with general random propylene. In order to solve this problem, an anti-blocking agent (hereinafter, referred to as AB agent) may be added to the innermost resin layer 14. The amount of the AB agent is added. For the resin layer to be added, 0 · 1 to 2 · 0 are used. % By weight is preferred. When the innermost resin layer 14 is a plurality of layers 14a and 14b, an AB agent may be added to the layer forming the adhesive surface. When AB agent is added to the innermost resin layer 14, it can improve the sliding property because the friction coefficient of the surface of the adhesive layer is reduced, and the secondary processing of polymer battery packaging materials can be more effective in bag making and groove processing. .

Also, Example 1 0-2 to Example 10-5 and Comparative Example 1 0-2 to Comparative Example 10-4 were produced as single-sided grooved packages, the grooves of which were 30x55mm, Those with a depth of 3.5mm. Regardless of the produced pouch form or embossed form, each of them was used for 1,000 sealed packages in which the polymer battery body was placed, and the following evaluations were performed. In addition, the width of the seal was 5 mm in both the Examples and Comparative Examples. (Evaluation method) This paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) 521035 Α7 Β7 V. Description of the invention (152) (1) Delamination, whitening, and cracks during pouching and groove forming After the pouch is formed and the groove is formed, it is confirmed whether there are delamination, whitening and cracks between the aluminum and the substrate layer. ί Please read the precautions on the back before filling in this page} (2) Resistance to content: Place each sample in a constant temperature bath at 60 ° C, 90% R Η for storage conditions. After 7 days of storage, confirm aluminum and adhesion Whether there is delamination between the base resin layer and the adhesive surface. (Results) In Examples 10-1 to 10-5, no whitening or cracking occurred during pouching or molding. In Comparative Example 101, fifteen of the 100 samples were found to have cracks in the bent portion of the inner surface of the pouch. In Comparative Examples 10-2, 50 of the 1000 samples were found to have a slight whitening phenomenon in the molding portion. In Examples 10 to 3, no problems such as whitening, cracks, and resistance to contents were found, but in Comparative Example 103, delamination was found in almost all of the resistance to contents. The Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs printed Examples 1 to 4. In addition to showing the 4 conditions such as the type and amount of additives, and showing stable molding performance, Comparative Example 104 was used in molding molding. 1 Wrinkles were formed in all the molded parts in the 0 samples, and sand holes were found in the 20 samples. In Examples 10 to 5, no whitening or cracking was found, and no problem was found in the content resistance. This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 521035 A7 _____B7 V. Description of the invention (153) In the polymer battery packaging material of the present invention, the innermost resin layer is made of ethylene-rich When acrylic is used, it can prevent the whitening or cracks in the bending part of the pouch and the formation of the groove, so that the sealing of the package has a significant stability effect. In addition, the surface treatment results are applied to both sides of aluminum, which can prevent delamination between the substrate layer and aluminum during the groove molding and heat sealing, and can prevent the reaction between the electrolyte and moisture of the polymer battery. The generated hydrogen fluoride corrodes the aluminum surface, so it is also very effective in preventing the separation between the aluminum and the side surface of the content. In addition, because the ethylene-rich random polypropylene film in the innermost resin layer uses acid-denatured PP as an adhesive resin and is laminated with a sandwich layer, it has excellent productivity, and is subjected to post-heat treatment, Under the heating state, the laminated surface of aluminum can be sandwiched to obtain the adhesive strength suitable for packaging materials for polymer batteries.
