Description
本発明は、リチウムイオン電池やリチウムポリマー電池等のリチウム二次電池やキャパシタに関する。 The present invention relates to lithium secondary batteries and capacitors such as lithium ion batteries and lithium polymer batteries.
リチウム二次電池は、過去に電池に起因する電気製品の発火事故があり、安全性を確保するための開発が進んでいる。しかしながら、近年、メーカーの純正品であるかのように偽った電池(以下、「模倣品」と称す。)が出回るようになった。模倣品には、電池として一定の性能を示すだけで、十分な品質管理がされていないものが多く、使用すると電気製品を破壊する恐れがあり、最悪の場合には火災、火傷、失明など、人体に影響する重大な事故を引き起こす恐れがある。同様の問題をキャパシタも抱えており、リチウム二次電池やキャパシタへの信頼性を高めるために、純正品と模倣品とを容易に判別する必要がある。そのため、純正品であることを簡単に判別でき、尚且つ、模造品を作ることが困難なリチウム二次電池及びキャパシタの出現が望まれている。 Lithium secondary batteries have been ignited in the past by electrical appliances caused by batteries, and are being developed to ensure safety. However, in recent years, a fake battery (hereinafter referred to as a “counterfeit”) has come to the market as if it were a genuine product of a manufacturer. Many counterfeit products only show a certain level of performance as a battery and are not adequately quality controlled.If used, there is a risk of destroying electrical products. In the worst case, fire, burns, blindness, etc. May cause serious accidents affecting human body. Capacitors have the same problem, and it is necessary to easily distinguish between genuine products and counterfeit products in order to increase the reliability of lithium secondary batteries and capacitors. Therefore, the advent of lithium secondary batteries and capacitors that can be easily identified as genuine and difficult to manufacture counterfeit products is desired.
尚、簡単な構成でありながら偽造されにくい物品の識別方法(特許文献1)や、信頼性を確保することができる真贋判定方法及び同装置(特許文献2)が提供されている。しかしながら、リチウム二次電池やキャパシタが抱えている問題についての記載はなく、むろんこれらの識別方法や真贋判定方法や装置を、リチウム二次電池やキャパシタの真贋判定に適用した例はない。 In addition, an identification method (Patent Document 1) of an article that has a simple configuration and is difficult to counterfeit, an authentication method and an apparatus (Patent Document 2) that can ensure reliability are provided. However, there is no description about the problem that the lithium secondary battery and the capacitor have, and there is, of course, no example in which these identification method and authentication method and apparatus are applied to the authentication of the lithium secondary battery and capacitor.
本発明が解決しようとする課題は、純正品か否かを簡単に判別でき、尚且つ模倣品を作ることが困難なリチウム二次電池及びキャパシタを提供することである。 The problem to be solved by the present invention is to provide a lithium secondary battery and a capacitor that can easily determine whether or not they are genuine products and that make it difficult to produce counterfeit products.
本発明によると上記課題を解決するための手段として、特定波長領域の電磁波の照射に対して特有の蛍光を放射する一種以上の元素群であって、且つ、放射する蛍光のスペクトル分布形状に対して特定の情報が関連付けられた物質を、基材層、バリア層、シーラント層が順次積層された外包材の、二軸延伸ポリエステルフィルムと二軸延伸ナイロンフィルムとからなる基材層のこれらを貼り合せるための接着剤層、もしくは基材層とバリア層とを積層する接着剤に含むことを特徴とするリチウム二次電池もしくはキャパシタが提供される。
According to the present invention, as a means for solving the above-mentioned problem, it is a group of one or more elements that emit specific fluorescence upon irradiation with electromagnetic waves in a specific wavelength region, and the spectral distribution shape of the emitted fluorescence. The material with specific information is attached to the base material layer consisting of a biaxially stretched polyester film and a biaxially stretched nylon film of an outer packaging material in which a base material layer, a barrier layer, and a sealant layer are sequentially laminated. Provided is a lithium secondary battery or a capacitor characterized in that the lithium secondary battery or the capacitor is included in an adhesive layer for bonding, or an adhesive for laminating a base material layer and a barrier layer.
更に、特定波長領域の電磁波の照射に対して特有の蛍光を放射する一種以上の元素群である物質の放射する蛍光のスペクトル分布形状に対して、特定の情報を関連付けるステップ、前記物質を用いて前記リチウム二次電池もしくはキャパシタを製造するステップ、該リチウム二次電池もしくはキャパシタに特定波長領域の電磁波を照射することで得られる蛍光のスペクトル分布形状により関連付けされた情報を認識するステップを備えることを特徴とする、リチウム二次電池もしくはキャパシタの識別方法が提供される。
A step of associating specific information with a spectral distribution shape of fluorescence emitted by a substance that is a group of one or more elements that emit fluorescence specific to electromagnetic wave irradiation in a specific wavelength region, using the substance Producing the lithium secondary battery or capacitor, and recognizing information associated with the spectral distribution shape of fluorescence obtained by irradiating the lithium secondary battery or capacitor with electromagnetic waves in a specific wavelength region. A feature of a method for identifying a lithium secondary battery or capacitor is provided.
本発明のリチウム二次電池もしくはキャパシタは、特定波長領域の電磁波の照射に対して特有の蛍光を放射する一種以上の元素群であって、且つ、放射する蛍光のスペクトル分布形状に対して特定の情報が関連付けられた物質(以下、情報提示物質と称す。)を、外装材に含んでいる。その為、本発明のリチウム二次電池もしくはキャパシタに特定波長領域の電磁波を照射すると、特有の蛍光を放射する。そして該蛍光のスペクトル分布を測定することによって、該スペクトル分布形状に対して関連付けられた情報を認識することができる。よって、あらかじめ情報提示物質の放射する蛍光のスペクトル分布形状に対して、電池やキャパシタのメーカー名等を関連付けておけば、電池やキャパシタに電磁波を照射し、放射される蛍光スペクトル分布を測定するだけで、電池やキャパシタのメーカー等を認識することができ、純正品であることを知ることができる。よって模倣品が出現したときに、これを排除することが可能となり、模倣品に起因する事故を防ぐことができる。
また情報提示物質が放射する蛍光のスペクトル分布形状は、元素の組み合わせや配合比率を変えると変化するため、元素と蛍光スペクトルとの関係を熟知しない第三者が、情報提示物質と全く同じスペクトル分布を示す物質を製造することは困難である。そのため、本発明の電池やキャパシタは模造品を作ることが非常に難しい。
The lithium secondary battery or capacitor of the present invention is a group of one or more elements that emit specific fluorescence upon irradiation with electromagnetic waves in a specific wavelength region, and is specific to the spectral distribution shape of the emitted fluorescence. The exterior material includes a substance associated with information (hereinafter referred to as an information presentation substance). Therefore, when the lithium secondary battery or capacitor of the present invention is irradiated with electromagnetic waves in a specific wavelength region, specific fluorescence is emitted. By measuring the spectral distribution of the fluorescence, information associated with the spectral distribution shape can be recognized. Therefore, if the manufacturer's name of the battery or capacitor is associated with the spectral distribution shape of the fluorescence emitted from the information-presenting substance in advance, the battery or capacitor is irradiated with electromagnetic waves, and the emitted fluorescent spectrum distribution is simply measured. Thus, the manufacturer of the battery or capacitor can be recognized, and it can be known that it is a genuine product. Therefore, when a counterfeit product appears, it can be eliminated, and an accident caused by the counterfeit product can be prevented.
In addition, the shape of the spectral distribution of the fluorescence emitted by the information-presenting substance changes when the combination of elements and the mixing ratio change, so a third party who is not familiar with the relationship between the element and the fluorescence spectrum has the same spectral distribution as the information-presenting substance. It is difficult to produce a material exhibiting Therefore, it is very difficult to make a counterfeit product for the battery or capacitor of the present invention.
本発明のリチウム二次電池もしくはキャパシタは外装材に情報提示物質を含む。該情報提示物質は、特定の波長領域の電磁波(たとえば所定波長領域の紫外線)の照射に対して、特有の蛍光を放射する一種以上の元素群であって、且つ、放射する蛍光のスペクトル形状に対して特定の情報が関連付けられた物質である。尚、情報提示物質が発する蛍光は、外部からの電磁波の照射によって、情報提示物質が基底準位からエネルギーの高い順位に励起され、その後エネルギーの低い順位に遷移する際に放射される。 The lithium secondary battery or capacitor of the present invention contains an information presenting substance in the exterior material. The information presenting substance is a group of one or more elements that emit specific fluorescence upon irradiation with electromagnetic waves in a specific wavelength region (for example, ultraviolet rays in a predetermined wavelength region), and has a spectral shape of the emitted fluorescence. It is a substance with specific information associated with it. The fluorescence emitted from the information presenting substance is emitted when the information presenting substance is excited from the ground level to the higher energy level by the external electromagnetic wave irradiation and then transitions to the lower energy level.
情報提示物質には、電池やキャパシタの外装材には一般に含有されていない元素が適し、具体的には原子番号31から原子番号88までの元素が適する。中でもランタノイド系元素、特に不完全4f軌道を有する遷移元素のセリウム(Ce)、プラゼオジム(Pr)、ネオジム(Nd)、プロメチウム(Pm)、サマリウム(Sm)、ユウロピウム(Eu)、ガドリニウム(Gd)、テルビウム(Tb)、ジスプロシウム(Dy)、ホルミウム(Ho)、エルビウム(Er)、ツリウム(Tm)、イッテルビウム(Yb)が適する。これらの元素は、スペクトル分布から特定が容易であり、更に経済的かつ衛生的で、酸化物としての入手も容易である。
そしてこれらの元素を単独で用いて情報提示物質としてもよいが、二種以上を組み合わせて情報提示物質としても良い。尚、同じ元素を含む情報提示物質であっても、組み合わせられる他の元素の種類や、組み合わせの比率が異なれば、放射される蛍光のスペクトル分布の形状が異なるため、別の情報提示物質として扱うことができる。
更に上述した情報提示物質はそのまま用いても良いが、化合物(酸化物、硫化物、有機錯体)にして用いてもよい。
As the information presenting substance, an element which is not generally contained in the battery or the outer packaging material of the capacitor is suitable, and specifically, an element having atomic number 31 to atomic number 88 is suitable. Among them, lanthanoid elements, particularly transition elements having incomplete 4f orbits such as cerium (Ce), praseodymium (Pr), neodymium (Nd), promethium (Pm), samarium (Sm), europium (Eu), gadolinium (Gd), Terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), and ytterbium (Yb) are suitable. These elements can be easily identified from the spectral distribution, are economical and hygienic, and are easily available as oxides.
These elements may be used alone to form an information presentation material, but two or more types may be combined to form an information presentation material. Even if the information presenting substance contains the same element, the shape of the spectrum distribution of the emitted fluorescence will be different if the type of other elements to be combined and the ratio of the combination are different. be able to.
Further, the information presenting substance described above may be used as it is, but may be used as a compound (oxide, sulfide, organic complex).
また情報提示物質は、ユーロピウムを含む酸化イットリウムのように、所定の母体物質に含有させてもよい。尚、母体物質には酸化物、硫化物、窒化物、水酸化物、ハロゲン化物、混晶、さらにはアモルファス物質、ガラスなども含まれる。たとえば、上述した元素がキレート化合物のように化学結合の形で含まれているもの、結晶格子を構成する他の原子またはイオンを置換したもの、結晶格子の中に割り込んで含まれるもの、あるいはガラスの中の隙間に含まれるものなどが挙げられる。
特に情報提示物質が、無機酸化物を母体材料とし、上述した元素が付与されたものであると、情報提示物質は非常に安定になり、1000℃の高温であっても破壊されない。よってこのような物質を情報提示物質として用いると、例え発火事故等によりリチウム二次電池やキャパシタが原型を留めない状態になっても、情報提示物質は破壊されず残るため、情報提示物質を特定し、情報提示物質に関連付けられた情報を認識することができる。
Further, the information presenting substance may be contained in a predetermined base substance such as yttrium oxide containing europium. The base material includes oxides, sulfides, nitrides, hydroxides, halides, mixed crystals, amorphous materials, and glass. For example, those containing the above-mentioned elements in the form of chemical bonds such as chelate compounds, those substituted with other atoms or ions constituting the crystal lattice, those included by being inserted into the crystal lattice, or glass What is contained in the gap in the inside.
In particular, when the information presenting substance is made of an inorganic oxide as a base material and added with the above-described elements, the information presenting substance becomes very stable and is not destroyed even at a high temperature of 1000 ° C. Therefore, if such a substance is used as an information presentation substance, the information presentation substance remains undestructed even if the lithium secondary battery or capacitor does not remain in its original state due to a fire accident, etc. Thus, the information associated with the information presenting substance can be recognized.
本発明においては、上記情報提示物質を外装材に含有させる必要がある。外装材は、リチウム二次電池やキャパシタの外装材として必要な性能を満たし、更に少なくとも一層に情報提示物質を含んでいれば特に限定されないが、一般的には、基材層、バリア層、シーラント層を基本構成とする。 In the present invention, it is necessary to include the information presenting substance in an exterior material. The packaging material is not particularly limited as long as it satisfies the performance required as a packaging material for a lithium secondary battery or a capacitor, and further contains an information presenting substance in at least one layer. In general, a base material layer, a barrier layer, a sealant The layer is the basic structure.
基材層は、外装材に強度や絶縁性をもたらす層であり、具体的には、二軸延伸ポリエステルフィルムや二軸延伸ナイロンフィルム等が適し、特に二軸延伸ポリエステルフィルムと二軸延伸ナイロンフィルムを積層した二層フィルムが適する。尚、この場合、ナイロン樹脂は電解液が付着した場合に変質するので、基材層の金属箔と接する層を二軸延伸ナイロンフィルムに、基材層の最外層となる層を二軸延伸ポリエステルフィルムとするのが好ましい。二軸延伸フィルムの具体的な製造方法は特に限定されないが、例えばポリエステル樹脂やナイロン樹脂をTダイ押出成形法を用いてフィルム状に製膜した後、テンター延伸機を用いて縦横二方向に延伸して製造する方法や、インフレーション押出成形法を用いてフィルム状に製膜しながら縦横二方向に延伸して製造する方法等がある。
尚、二軸延伸ポリエステルフィルムは、例えばポリエチレンテレフタレート、ポリブチレンテレフタレート、ポリエチレンナフタレート、エチレンテレフタレート/エチレンイソフタレート共重合体やブチレンテレフタレート/ブチレンイソフタレート共重合体等の共重合ポリエステル等の樹脂から成形することができ、二軸延伸ナイロンフィルムは、ナイロン6、ナイロン6,6、ナイロン6,6とナイロン6との共重合体、ナイロン6,10、ポリメタキシリレンアジパミド(MXD6)等の樹脂から成形することができる。
The base material layer is a layer that provides strength and insulation to the exterior material. Specifically, a biaxially stretched polyester film or a biaxially stretched nylon film is suitable, and in particular, a biaxially stretched polyester film and a biaxially stretched nylon film. A two-layer film in which is laminated is suitable. In this case, since the nylon resin is altered when the electrolytic solution adheres, the layer in contact with the metal foil of the base material layer is a biaxially stretched nylon film, and the layer that is the outermost layer of the base material layer is a biaxially stretched polyester. A film is preferred. Although the specific manufacturing method of a biaxially stretched film is not specifically limited, for example, after forming a polyester resin or a nylon resin into a film shape by using a T-die extrusion method, the film is stretched in two directions in the vertical and horizontal directions using a tenter stretching machine. And a method of stretching and producing in two longitudinal and lateral directions while forming a film using an inflation extrusion molding method.
The biaxially stretched polyester film is formed from a resin such as a copolymer polyester such as polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, ethylene terephthalate / ethylene isophthalate copolymer or butylene terephthalate / butylene isophthalate copolymer. The biaxially stretched nylon film is made of a resin such as nylon 6, nylon 6,6, a copolymer of nylon 6,6 and nylon 6, nylon 6,10, polymetaxylylene adipamide (MXD6), etc. Can be molded from
バリア層は、外部から電池内部に水蒸気が浸入することを防止するための層である。バリア層としてはアルミニウム、ニッケル、ステンレス等の金属箔を用いるとよいが、経済性を考慮するとアルミニウム箔を用いることが好ましい。尚、アルミニウム箔は若干の鉄を含有することで展延性が改善されること、折り曲げによるピンホールの発生が少なくなることが知られている。そこでバリア層としてアルミニウム箔を用いる場合は、鉄を0.3〜9.0重量%、好ましくは0.7〜2.0重量%含有したものを用いとよい。また、冷間圧延で製造されるアルミニウム箔は焼きなまし(いわゆる焼鈍処理)条件でその柔軟性・腰の強さ・硬さが変化するが、本発明においてアルミニウム箔を用いる場合は、焼きなましをしていない硬質処理品より、多少または完全に焼きなまし処理をした軟質傾向にあるものがよい。 The barrier layer is a layer for preventing water vapor from entering the battery from the outside. As the barrier layer, a metal foil such as aluminum, nickel, and stainless steel may be used, but it is preferable to use an aluminum foil in consideration of economy. In addition, it is known that aluminum foil contains a slight amount of iron to improve the spreadability and to reduce the occurrence of pinholes due to bending. Therefore, when an aluminum foil is used as the barrier layer, it is preferable to use one containing 0.3 to 9.0% by weight, preferably 0.7 to 2.0% by weight of iron. In addition, the aluminum foil produced by cold rolling changes its flexibility, waist strength, and hardness under annealing (so-called annealing treatment) conditions. However, when aluminum foil is used in the present invention, it is annealed. It is better to have a soft tendency to be annealed somewhat or completely than a hard-treated product.
また、金属箔(特にアルミニウム箔)は酸性物質等によって表面が溶解、腐食しやすい。そこでバリア層には耐酸処理を行うことが望ましい。耐酸処理を行うと、電池等の内部からフッ酸等の酸性物質等が発生した場合であっても、バリア層表面の溶解、腐食を防止し、バリア層にピンホールが発生する事を防止する。更に耐酸処理はバリア層とシーラント層との密着力を向上させる効果も奏す。耐酸処理方法としては、クロメート処理が一般的であるが、ベーマイト処理、パーカライジング処理、トリアジンチオール処理等の非クロメート系処理等も可能である。また、バリア層のシーラント層側の面だけに耐酸処理を施しても良いが、両面に施しても良い。 Moreover, the surface of metal foil (particularly aluminum foil) is easily dissolved and corroded by an acidic substance or the like. Therefore, it is desirable to perform acid resistance treatment on the barrier layer. When acid-resistant treatment is performed, even if acidic substances such as hydrofluoric acid are generated from the inside of the battery, etc., the barrier layer surface is prevented from dissolving and corroding, and pinholes are prevented from being generated in the barrier layer. . Furthermore, the acid resistance treatment also has the effect of improving the adhesion between the barrier layer and the sealant layer. As an acid-resistant treatment method, chromate treatment is generally used, but non-chromate treatment such as boehmite treatment, parkerizing treatment, triazine thiol treatment, and the like are also possible. Moreover, although the acid-resistant treatment may be performed only on the surface of the barrier layer on the sealant layer side, it may be performed on both surfaces.
次にシーラント層について説明する。シーラント層は、低密度ポリエチレン、高密度ポリエチレン、エチレン−αオレフィン共重合体等のポリエチレン系樹脂や、ポリプロピレン、プロピレン・エチレン共重合体等のポリプロピレン系樹脂、これらの樹脂を不飽和カルボン酸やアクリル酸、メタクリル酸、無水マレイン酸等で変性した樹脂やイオン架橋した樹脂等から形成される。
またシーラント層は、変性していないポリエチレン系樹脂やポリプロピレン系樹脂からなる層(以下、無変性樹脂層とする。)と、不飽和カルボン酸やアクリル酸、メタクリル酸、無水マレイン酸等で変性したポリエチレン系樹脂やポリプロピレン系樹脂(以下、変性樹脂層とする。)からなる二層であってもよい。シーラント層が変性樹脂層と無変性樹脂層の二層で、基材層/バリア層/変性樹脂層/無変性樹脂層が順次積層されてなる外装材は、バリア層とシーラント層との密着力が良好で、更にヒートシール性にも優れる。
Next, the sealant layer will be described. The sealant layer is made of polyethylene resin such as low density polyethylene, high density polyethylene, and ethylene-α olefin copolymer, polypropylene resin such as polypropylene and propylene / ethylene copolymer, and these resins are mixed with unsaturated carboxylic acid or acrylic resin. It is formed from a resin modified with acid, methacrylic acid, maleic anhydride, or the like, or an ion-crosslinked resin.
The sealant layer was modified with a layer made of unmodified polyethylene resin or polypropylene resin (hereinafter referred to as an unmodified resin layer), and unsaturated carboxylic acid, acrylic acid, methacrylic acid, maleic anhydride, or the like. It may be a two-layer made of a polyethylene resin or a polypropylene resin (hereinafter referred to as a modified resin layer). The exterior material in which the sealant layer is composed of two layers, a modified resin layer and an unmodified resin layer, and the base material layer / barrier layer / modified resin layer / non-modified resin layer are laminated in order, has an adhesive force between the barrier layer and the sealant layer. In addition, the heat sealability is also excellent.
尚、基材層、バリア層、シーラント層の貼り合せ方法については、特に限定しないが、例えば、初めにバリア層の片面に基材層を接着剤にて貼り合せ、次いでバリア層の他面にシーラント層を熱圧着して貼り合わせるとよい。 The method for bonding the base material layer, the barrier layer, and the sealant layer is not particularly limited. For example, the base material layer is first bonded to one side of the barrier layer with an adhesive, and then to the other side of the barrier layer. The sealant layer may be bonded by thermocompression bonding.
これらの外包材に情報提示物質を含ませる方法について、特に限定はしないが、前述したようにバリア層は金属箔が好適に用いられる為、バリア層やシーラント層に情報提示物質が配されていると、電磁波は金属箔を透過しないため電池やキャパシタを破壊しないと電磁波が情報提示物質に届かない恐れがある。よって非破壊で情報提示物質を特定するためには、情報提示物質はバリア層よりも外側に配されていなければならない。その為には、(1)情報提示物質を基材層とバリア層とを貼り合わせるための接着剤に添加する、或いは(2)情報提示物質を基材層中に配する、或いは(3)基材層上に情報提示物質を含む分散液を印刷するとよい。 Although there is no particular limitation on the method of including the information presenting substance in these outer packaging materials, as described above, since the metal foil is suitably used for the barrier layer, the information presenting substance is arranged in the barrier layer and the sealant layer. Then, since the electromagnetic wave does not pass through the metal foil, the electromagnetic wave may not reach the information presenting substance unless the battery or the capacitor is destroyed. Therefore, in order to specify the information presenting substance in a non-destructive manner, the information presenting substance must be disposed outside the barrier layer. For this purpose, (1) the information presentation substance is added to an adhesive for bonding the base material layer and the barrier layer, or (2) the information presentation substance is arranged in the base material layer, or (3) A dispersion liquid containing the information presenting substance may be printed on the base material layer.
尚、(2)情報提示物質を基材層中に含むためには、基材層を成す樹脂にあらかじめ情報提示物質を練り込んでもよいが、基材層が二軸延伸ポリエステルフィルムと二軸延伸ナイロンフィルムとの積層フィルムである場合は、これらを貼り合わせるための接着剤層に添加してもよい。 In addition, (2) In order to include the information presenting substance in the base material layer, the information presenting substance may be kneaded in advance in the resin constituting the base material layer, but the base material layer is biaxially stretched with the biaxially stretched polyester film. When it is a laminated film with a nylon film, it may be added to an adhesive layer for bonding them together.
また(3)基材層上に情報提示物質を含む分散液を印刷するためには、例えば、アクリル系、アクリルウレタン系、アクリルアミド系等のバインダー成分に情報提示物質を分散させ、これをグラビア印刷やインクジェット印刷等で印刷すると良い。また、該印刷は基材層全面に行っても良く、基材層の一部に行ってもよく、更には文字や図、バーコード等の形に行っても良い。可視光領域の蛍光を放射する情報提示物質を用いて、文字や図、バーコード等の形に印刷しておくと、電池やキャパシタに特定波長領域の電磁波を照射することにより、文字や図を浮かびあがらせることもできる。 (3) In order to print a dispersion liquid containing an information presenting substance on a base material layer, for example, the information presenting substance is dispersed in a binder component such as acrylic, acrylurethane or acrylamide, and this is subjected to gravure printing. Or by inkjet printing. The printing may be performed on the entire surface of the base material layer, may be performed on a part of the base material layer, and may be performed in the form of characters, figures, barcodes, and the like. Using an information presentation substance that emits fluorescence in the visible light region and printing it in the form of letters, diagrams, barcodes, etc., by irradiating the battery or capacitor with electromagnetic waves in a specific wavelength region, It can also be raised.
尚、異なった情報提示物質を含む外装材を少量ずつ製造する場合は、(3)基材層上に情報提示物質を印刷する方法が適する。あらかじめ多量の外装材を製造し、その後少量ずつ異なった情報提示物質を印刷していくことによって、多品種の外装材を効率よく製造できる。また、情報提示物質を印刷する場合、摩擦などで情報提示物質が剥がれ落ちる恐れがある。よって、(3)基材層上に情報提示物質を印刷する場合は、情報提示物質を含む印刷層を保護する目的で、更にハードコート層などの保護層を設けることがこの望ましい。なお該保護層は、印刷層のバインダー成分のみを再度印刷することによって設けることができる。 In addition, when manufacturing the exterior material containing a different information presentation substance little by little, (3) The method of printing an information presentation substance on a base material layer is suitable. A wide variety of exterior materials can be efficiently manufactured by manufacturing a large amount of exterior materials in advance and then printing different information-presenting substances in small amounts. Further, when printing the information presentation material, the information presentation material may be peeled off due to friction or the like. Therefore, (3) when the information presentation substance is printed on the base material layer, it is desirable to further provide a protective layer such as a hard coat layer for the purpose of protecting the printing layer containing the information presentation substance. The protective layer can be provided by printing again only the binder component of the printing layer.
リチウム二次電池は、上述した外装材を袋状あるいはトレー状に成形し、正極集電材と正極活性物質層からなる正極材料と、電解液を浸潤したポリマー電解質層と、負極集電材や負極活性物質層からなる負極材料とを積層した電池本体を挿入し、次いで正極リードおよび負極リードを、一端が各極材料、他端が容器外部に位置するように容器に差し込み、最後に容器を密封して製造するとよい。あるいは、正極材料とセパレータと負極材料とを積層し、これを容器に挿入した後、電解液を充填し、最後に正極リードと負極リードを差し込み、容器を密封して製造するとよい。またキャパシタは、上述した外装材を袋状あるいはトレー状に成形し、アルミニウムの集電板の間に電解液を浸潤させた活性炭の電極とセパレータを挟んだ積層体を、集電板の一端を容器外部に突出させながら封入して製造するとよい。 The lithium secondary battery is formed by forming the above-described exterior material into a bag shape or a tray shape, a positive electrode material composed of a positive electrode current collector and a positive electrode active material layer, a polymer electrolyte layer infiltrated with an electrolytic solution, a negative electrode current collector and a negative electrode active material. Insert the battery body laminated with the negative electrode material consisting of the material layer, then insert the positive electrode lead and negative electrode lead into the container so that one end is each electrode material and the other end is outside the container, and finally the container is sealed It is good to manufacture. Alternatively, a positive electrode material, a separator, and a negative electrode material may be laminated, inserted into a container, filled with an electrolytic solution, and finally, the positive electrode lead and the negative electrode lead may be inserted and the container sealed. In addition, the capacitor is formed by stacking the above-described exterior material into a bag shape or a tray shape, and sandwiching an activated carbon electrode and a separator infiltrated with an electrolyte between aluminum current collector plates, and one end of the current collector plate outside the container. It is good to manufacture by enclosing while projecting.
尚、情報提示物質が放射する蛍光のスペクトル分布形状が示す情報は、製造工場名、組み込まれるべき電気製品名等、電池やキャパシタが必要とする情報が含まれていれば特に限定されないが、電池やキャパシタのメーカー名を関連付けておけば、純正品であること分かりやすい。
また情報提示物質が放射するスペクトル分布形状とそれに関連付けられたメーカー名等の情報を記憶する手段と、電磁波を照射する装置や蛍光スペクトル検出機等の情報提示物質からスペクトル分布を取り出すための手段と、取り出されたスペクトル分布の形状からメーカー名等の情報を照会してアウトプットする手段とを兼ね備えた「情報管理装置」を用いると、該装置に電池やキャパシタを供給するだけで、メーカー名等の情報を取り出すことができ、純正品の判定をすることができる。
尚、電磁波としてはγ線、X線、紫外線などを用いることができる。具体的には特定の波長の紫外光を例示でき、紫外光を照射する光源としては、水銀ランプやメタルハライドランプ等を例示できる。
The information indicated by the spectral distribution shape of the fluorescence emitted by the information-presenting substance is not particularly limited as long as it includes information required by the battery and capacitor, such as the name of the manufacturing factory and the name of the electrical product to be incorporated. If you associate the manufacturer name of the capacitor and capacitor, it is easy to understand that it is a genuine product.
Also, means for storing information such as the spectrum distribution shape emitted by the information presenting substance and the manufacturer name associated therewith, means for extracting the spectrum distribution from the information presenting substance such as an electromagnetic wave irradiating apparatus or a fluorescence spectrum detector, and the like Using an “information management device” that also has a means for querying and outputting information such as the manufacturer name from the shape of the extracted spectrum distribution, the manufacturer name, etc. can be obtained simply by supplying a battery or capacitor to the device. Information can be extracted, and genuine products can be determined.
Note that γ rays, X rays, ultraviolet rays, and the like can be used as the electromagnetic waves. Specifically, ultraviolet light having a specific wavelength can be exemplified, and examples of the light source for irradiating ultraviolet light include a mercury lamp and a metal halide lamp.
次に実施例を挙げて本発明を説明するが、これに限定されるものではない。
まず、情報提示物質を含まない外装材を製造する。初めに二軸延伸ナイロンフィルムと二軸延伸ポリエステルフィルムとを、接着剤を介して貼り合せて基材層を得る。次にアルミニウム箔の片面にクロメート処理を行い、これをバリア層とする。また無水マレイン酸変性ポリプロピレン層とプロピレン・エチレン共重合体層を有する二層フィルムを製造し、これをシーラント層とする。
次いで、基材層、バリア層、シーラント層を貼り合わせる。尚、基材層とバリア層との貼り合せは接着剤を用い、基材層の二軸延伸ナイロンフィルム層とバリア層のクロメート処理を行っていない面が接するように貼り合せた。バリア層とシーラント層との貼り合せは接着剤を用いずに加熱圧着により行い、バリア層のクロメート処理面と無水マレイン酸変性ポリプロピレン層とが接するように貼り合せた。
Next, the present invention will be described with reference to examples, but the present invention is not limited thereto.
First, an exterior material that does not contain an information presentation substance is manufactured. First, a biaxially stretched nylon film and a biaxially stretched polyester film are bonded together via an adhesive to obtain a base material layer. Next, chromate treatment is performed on one surface of the aluminum foil, and this is used as a barrier layer. In addition, a two-layer film having a maleic anhydride-modified polypropylene layer and a propylene / ethylene copolymer layer is produced and used as a sealant layer.
Subsequently, a base material layer, a barrier layer, and a sealant layer are bonded together. The base material layer and the barrier layer were attached using an adhesive so that the biaxially stretched nylon film layer of the base material layer and the surface of the barrier layer not subjected to the chromate treatment were in contact with each other. The barrier layer and the sealant layer were bonded together by thermocompression bonding without using an adhesive, and bonded so that the chromate-treated surface of the barrier layer was in contact with the maleic anhydride-modified polypropylene layer.
次に、特定波長領域の電磁波の照射に対して特有の蛍光を放射する元素群であって、放射する蛍光のスペクトル分布形状に対して「○×会社」という情報が関連付けられた物質(情報提示物質)をバインダーに分散させ、分散液を作製する。この分散液を、グラビア印刷機にて、外装材の基材層全面に印刷した。更に、該外装材を袋状に成形し、電池本体を挿入して、本発明のリチウム二次電池を製造した。 Next, a group of elements that emit specific fluorescence upon irradiation with electromagnetic waves in a specific wavelength region, and a substance (information presentation) associated with the information “○ × company” to the spectrum distribution shape of the emitted fluorescence Material) is dispersed in a binder to prepare a dispersion.
