Description of the Invention: [Technical Field of the Invention] The object of the present invention is to make a sorghum by using an innovation of a fabric and a processing method for fabricating a lithium ion battery cover using a sandwich & 〇 is used to prepare a long-lasting lithium ion battery. Revealed for the use of I as the cover of the new type, structure and # yourself ^ friends you extend the use of synthetic batteries - traitors. SUMMARY OF THE INVENTION The present invention provides a battery for long-term applications such as the use of home electric vehicles, storage applications, or hybrid electric applications. [Prior Art] = H_etie seal system often determines the key to the __ sub-cell, because the high-electro-ink of this battery will provide water decomposition when the gas molecules are present in the electrolyte. Or oxygen is reduced. This question often causes improper battery seals. Traditionally, the ion battery has been small in size and capacity. A 1865-inch cylindrical battery is used as an example. The size of the battery is 18 mm in diameter and "mm" in height. This battery capacity is about 2.8 Ah to 1.4 Ah depending on the type of cathode material being used. In the scope of the outer cover construction, the metal-to-polymer interface at the collector of the battery is usually small (only supported by a shape such as a -0-ring-insulation layer), and This interface thus does not provide a long diffusion path to penetrate the metal to the polymer interface of oxygen, water molecules or other gases or liquids. Because of the accelerated decompression of the metal to polymer interface, the foregoing is once When the battery is subjected to high temperature cycling conditions (for example, conditions such as continuous high power operation), the same problem occurs in other types of lithium ions such as prismatic batteries or even 201140904 lithium polymer type batteries. [Explanation] A cover assembly for a lithium ion battery container has an outer cover for sealing a top opening of a battery container, the outer cover is defined For one or more openings of the current collecting column, the outer cover assembly further comprises: a collecting column that extends through each opening and has a gap between the collecting raft and the outer cover a column, arranged to be opposite and offset from the current collecting column outwardly radially beyond the opening around each of the collecting columns, disposed as a surface, and from the collecting column to the outer diameter and a first polymer body, The polymer main system is spliced to the attached and bottom flanges between the outer and the bottom flanges. The top flange is wrapped around each of the outer covers. a top surface, and an edge from the port; a bottom flange that is opposite and offset from a bottom portion of the outer cover extending beyond the edge of the opening; for each current collecting column. The first polymer main cover, the first polymer The current collecting column, all the gaps formed by the top flange, and the outer cover, the collecting column and the top flange of the first contact are for the purpose of improving the above problem, and the disclosed structure has a cover for manufacturing One of the outer lids of the pool container Appropriate structure and methodologies implemented. Misplaced in the battery capacity has an extended service life (target: long-lasting clock ion battery can be expected on such as electric vehicle surface or hybrid electric system. Large power of high power capability (= large battery (capacity of more than 1 〇Ah) used in long-term service sub-systems and/or high-power applications 201140904, especially at these tributaries A good seal is important. [Embodiment] The key concepts applied to the outer cover structure are as follows: a. Increasing the diffusion path of gas and/or liquid into or out of the battery b. Strengthening the collector of the battery A metal to polymer interface. Example I · Basic Form of the Invention Figure 1 (a) shows a top view of an outer cover 1 open to the top of a battery container. To clearly illustrate the method of the present invention, the stepwise assembly of the outer cover is shown in the form of a side view of Figures 1(b) through 1(f). Figure 1 (b) shows the first step for making the outer cover assembly. - The first polymer body 2 is disposed on a top surface and a bottom surface of the container cover 1 through an injection molding process. The header 3 extending through the opening 4 in the outer lid is stabilized by the injection molding process by filling the polymer with a gap between the outer lid and the headers. Figure 1 (c) shows the top flange 5 and a bottom flange 6 disposed on the conductive column. The flanges are forced toward each other and the injection molding polymer master system is sandwiched between the two. The top flange and the bottom flange are welded to the injection molded polymer. This step is extremely important and is preferably performed at a temperature close to the softening point of the polymer. The advantages of the flanges being forced toward each other (preferably using a smashing smash, using a screw, a wire mechanism to bolt the top flange and the bottom flange together on a bolt or the like) are summarized as follows : 1. The contact between the injection molded polymer and the edge of the top flange and the bottom projection 6 201140904 is welded and welded. 2. Ensuring that the contact between the polymer and the collectors of the slain slain i:::, 丨糸 is not important, as batteries that are often subjected to high power operation may cause the polymer With the retreat (four) f between the current collecting columns, Figure 1 U) shows that the separating insulating layer 7 is at least arranged on the bottom table of each bottom flange and w " for isolating the bottom flange and the battery The electrodes also block the line leakage 8 that occurs at the interface between the current collecting column and the injection molded polymer. ▲ Figure 1 U) shows the welded 9 (for example: the lightning connection method and the top flange of the collecting column to prevent gas or liquid molecules from penetrating from the interface between the top flange and the collecting column) Any possibility. Finally, as shown in Figure ICf), the area at the top flange is filled with the == body 1〇 to ensure the first polymerization at the edge of the top flange and the injector. There is no leakage at the interface between the subjects. = The key factors and methods involved in making the outer cover shown in the actual needle of the present invention are summarized as follows: a. Injection molding for making the outer cover monomer containing the current collecting columns. b. By chasing the top and bottom flanges toward each other, the outer cover of the dust cover. ° C. Apply the insulation material to the bottom surface of each bottom flange. d. Laser splicing between the top flanges and the collectors. e. filling the second polymer into the first injection molded first body to block the edge of the top flange and the first permeable. The key factors and methods involved in making the aforementioned outer cover between the blade bodies are indispensable for solving the problems listed in the following list of 201140904. 1. The injection molding process can be used to cover a cover sheet. Preferably, because the first polymer body and the outside of the container: high pressure treatment, so the container:? first. Because the injection molding process is - showing that the polymer system having the preferred I ^ "top cut arrangement can distinguish the feature "texture" from the body orientation, wherein the system can (4) the field product is fed on the top of the container cover. . Injection molding process and "outer cover / polymer monomer evening: ensure the integration of the interface. One... early body" one structural system 2 ^ Invented novelty is indispensable. Interface. Between the turbulent column and the injection-molded first polymer body; This is also caused by the fact that the top flange and the 1 wide polymer material are forced to weld both the flange and the flange to the first gather of the injection molding. Diffusion road control. Without the top flange and the bottom of the 悴, π / and the use of the δ 玄 top flange and the bottom flange two, no leakage can be more likely to occur due to a shorter diffusion path in (four) - injection molding - at the interface between the polymer bodies. ...the other steps involved in blocking any new interface when using the top flange and the bottom flange are indispensable. This step is to wrap the insulation (4) coated on the bottom surface of the flange (which will pass through the leaked: the "column" surface and the possible two-way leakage from the entering or leaving the battery: the penetration is delayed" As indicated in Figure i(4); the laser recording between the top flange collectors' (to avoid leakage through the top convex, 'and the interface of the current collector'" as indicated in Figure 1(e) And more than one layer of polymer coating to protect the edge of the top flange (to avoid leakage through the interface of the edge of the top flange of 8 201140904, as shown in Figure 丨 (the polymer of the injection molding uses θ not Limited to polyethylene (ΡΕ), poly, select system ^ ^ a non-p-phenylene 4-acid vinegar (ΡΕ = ), poly gas 酉 (called, nylon, (na), fluorinated B (four) diced Ethylene copolymer (w^, poly(tetra)cyano/i (FEP), poly-imine

In the present example, if the injection _ a polymer interfacing the top flange and the bottom flange and The current collecting columns and the surface of the outer cover are not sufficiently spliced, and the bottom layer u should be used to melt the top polymer edge/the injection molded first polymer body, the bottom flange/ The injection molding of the first polymer body, the current collecting column / the injection molded first polymer body, and the outer cover surface / the injection molded first polymer body: (see Figure 1 ( g) as indicated. The material used for the bottom layer is styrene type, adhesive, or any other material that has excellent adhesion to the metal surface and the shot. In addition, the bottom layer 10 201140904 can be dazzled. An anodic polarization layer on the metal surface that increases the coarseness of the metal surface to enhance adhesion of the metal to the polymer layer. - Anodically polarized metal surface and combined with one of the polymer underlayers The system is also encompassed by the present invention. EXAMPLE II: Components of an Alternative Form of the Invention Referring to Figures 2(a) through 2(c), a header, a top flange, a bottom flange, and an outer cover are advanced via mechanical assembly or welding. Assembly. In the configuration shown in Fig. 2(a), a plurality of current collecting columns, a top flange, and a bottom flange are assembled using a mold-relative-outer cover, and a polymer injection molding system is carried out throughout the assembly. on. The resulting outer cover is changed to the H shown in Figure 2 jb). The top flanges are then sealed to the headers. The subsequent first injection of the first polymer as shown in Figure 2 (c) : The top of the body is filled with a second polymer body. Since the sorghum is used during the injection molding: the conditional filaments are subjected to the 5L treatment of the present invention in the first manufacturing method as described above in which the top = and the bottom rim are forced toward each other. It should be noted that a seal system such as laser welding can be used between the top flange and the collector to perform the injection molding process: The collector column, the top flange, can be made by assembling two sections # (in which one of the aforementioned combined components is a collector/top flange assembly or a collector/bottom flange group 1) The components of the bottom flange are pressed into the pressure: two of the components are made separately by adding a metal block, casting or squeezing the metal. The outer cover of the sifter can be designed in any shape (for example: round Shape, ellipses, rectangles, etc., and the edges are shaped to be flat except for the shape (see 201140904 t see all the patterns in 3(e)). In the figure, "(1), all the valley cover The edge is made of m,, m ^ ^ ^ having a lip-like structure for further increasing the diffusion length and polymer/cover interface integration. Soldering the cover to the battery container electrolyte of the finished battery The system can be inserted into the crucible 12 to stand 4...n, and the final sealing system can be welded to the top of the injection crucible 12 by misaligning the metal ball 13 or a small cover 1 4 to the square. The upper layer is shown in Fig. 2(d). Similar to the underlying material to be used in the example 1, in the example of the present invention, The injection molding polymer does not exhibit sufficient interfacial properties (attachment or splicing) to the top flange and the bottom flange and the surface of the outer cover, and the underlying material system can be applied to the surface of the flange first. On the surface, at the interface between the top flange / the injection molded polymer, the bottom flange / the injection molding polymer (4) g / the (tetra) 0 polymer, and the outer cover surface / the injection molded polymer (eg Figure i), g; does not) refining occurs during the subsequent injection molding process. The material used for the underlayer is styrene butadiene rubber (SBR), an adhesive, or any other material having excellent adhesion to the metal surface and the polymerized polymer. In addition, the underlayer can be an anodic polarization layer on the surface of the metal to be fused, which increases the roughness of the metal surface to enhance the metal's J properties to the polymer layer. The combination of an anodically polarized metal surface and a polymeric underlayer is also encompassed by the present invention. Example III. An extension of the invention - The battery cover may contain not only the openings of the positive and negative collector columns, but also additional openings for electrolyte filling or safe access. 12 201140904 More than one embodiment is provided herein for the design and method of making a battery cover, including a plurality of current collecting columns, an electrolyte filling opening, and a safety vent. For the sake of clarity, the method described in Example II is utilized in the practice of the present invention: Figure 3 (a) shows that the outer cover is notched 15 in the opening β for electrolyte filling. The gap having a reduced metal thickness is designed as an Anwang port, which is outwardly broken when the internal battery pressure is abnormally increased; the IL column, a top flange and a bottom flange are mechanically assembled. It was assembled first. In the configuration shown in FIG. 3(a), a plurality of current collecting columns, a top flange, and a bottom flange are made using a mold, and are mounted with respect to the outer cover, and then the injection molding system is carried out. On the entire component. The resulting outer cover is changed to a monomer 18 as shown in Fig. 3(b). By adjusting the shape of the mold during the injection molding process, the ejected polymer system can be selected to completely cover the indentations, partially cover (at a shallower depth), and to cover the indentations. In Fig. 3(b), the exiting polymer portion covers the gaps. Partial coverage is preferred, as the gap is protected by the polymer layer, but the polymer layer does not significantly impede its normal enthalpy. The top flange of the crucible is then sealed to the current collecting column, and then a second: compound body is provided on top of the injection molded first polymer body as shown in Figure 3 (c). It should be noted that the second polymer main system can be completed: covering the notched area, partially covering (with a shallow depth), or not covering the gap: The second polymer body shown in Fig. 3(c)t' has a region covering the gap (safety port) for a long time. In the present example, the outer cover structure must be limited to the configuration and design of the safety port "this electrolyte 13 201140904 injection" shown in Figure $. Additional examples are given herein for the configuration and design of the safety port and the electrolyte injection port. For example, as shown in FIG. 3(d), a safety port can be designed to be combined with the injection port; or as shown in FIG. 3(e), the safety port can be installed as one of the battery covers. Separate an independent design mechanism at position 17. In all of the examples given above, increasing the distance to one of the diffusion paths and any openings present on the outer cover of the battery to enhance the metal-on-polymer interface forms the basis of the present invention, "collector, electrolyte injection" The location and shape design of the safety port is not limited to the given example in the inventive example. The structure of the polymer layer and the method for constructing a battery cover 2 are any combination and number of (4) flow columns, electrolysis and safety ports on the top of the battery cover to be present. The present invention is also applied in a configuration in which the container and the outer cover replace the current collecting column and only require one m.
