Description

本発明は、二次電池システムに関し、詳しくは、異常時に二次電池から発せられた有色物質による視界の減少が抑えられた二次電池システムに関する。   The present invention relates to a secondary battery system, and more particularly, to a secondary battery system in which a reduction in visibility due to a colored substance emitted from a secondary battery in an abnormal state is suppressed.

近年、環境汚染が地球規模で大きな問題となっており、特に、ガソリン自動車の排気ガスは大気汚染の汚染源の一つとなっている。このため、排気ガスの排出量を低減させた自動車や排気ガスを出さない自動車の開発が進められている。排気ガスの排出量を低減させた自動車の一つとして、内燃機関と電気モータとを組み合わせたハイブリッド自動車がある。また、排気ガスを出さない自動車の一つとして、電気自動車がある。これらの自動車には二次電池が搭載されており、この二次電池として、鉛電池、Ｎｉ−Ｃｄ電池、Ｎｉ−ＭＨ電池、リチウム電池などの二次電池が開発されてきた。中でもリチウム電池は、単電池電圧が４Ｖ程度有り、他の電池よりエネルギー密度が高いことが特徴であり、次世代の自動車用の二次電池として注目されている。しかし、リチウム電池は、電池電圧が４Ｖ程度あることから電解液には電気分解されないように、他の電池と異なり有機系の電解液が用いられている。   In recent years, environmental pollution has become a major problem on a global scale, and in particular, exhaust gas from gasoline automobiles has become one of the sources of air pollution. For this reason, development of automobiles with reduced exhaust gas emissions and automobiles that do not emit exhaust gas has been underway. As one of vehicles that reduce exhaust gas emissions, there is a hybrid vehicle that combines an internal combustion engine and an electric motor. An electric vehicle is one of the vehicles that does not emit exhaust gas. Secondary batteries are mounted on these automobiles, and secondary batteries such as lead batteries, Ni-Cd batteries, Ni-MH batteries, and lithium batteries have been developed as the secondary batteries. Among them, the lithium battery has a single cell voltage of about 4 V and is characterized by a higher energy density than other batteries, and is attracting attention as a secondary battery for next-generation automobiles. However, since lithium batteries have a battery voltage of about 4 V, organic electrolytes are used unlike other batteries so that the batteries are not electrolyzed.

リチウム電池は、エネルギー密度が高い為に、過充電、短絡などの誤った使用をすると電解液が分解してガスが発生するとともにこのガス中に正・負極活物質粉塵などからなる有色物質粒子が含まれる有色ガスが電池（ケース）内部から外部に排出されることがある。誤使用時に発生した有色ガスをそのまま車外に放出されるという問題があった。   Lithium batteries have a high energy density, so if they are used incorrectly such as overcharged or short-circuited, the electrolyte will decompose and gas will be generated, and colored substance particles consisting of positive and negative electrode active material dust will be contained in this gas. The colored gas contained may be discharged from the inside of the battery (case) to the outside. There was a problem that the colored gas generated at the time of misuse was released to the outside as it was.

このような課題に対して、たとえば、特許文献１〜３が開示されている。   For such a problem, for example, Patent Documents 1 to 3 are disclosed.

特許文献１は、電池の内部の安全弁と電池蓋の間に吸着材を配設することを提案している。特許文献２は、電池から発生したガスを電池外の酸素が存在しない空間に移動させることを提案している。特許文献３は、イオン交換樹脂を使用して、電池から放出される電解液の酸およびアルカリ成分を補足することを提案している。   Patent Document 1 proposes disposing an adsorbent between a safety valve inside the battery and the battery lid. Patent Document 2 proposes that gas generated from a battery is moved to a space outside the battery where oxygen is not present. Patent Document 3 proposes using an ion exchange resin to supplement the acid and alkali components of the electrolytic solution discharged from the battery.

しかしながら、特許文献１に記載の発明は、電池内部の限られた空間内部に吸着材を配することから、吸着材を配置するための容積に限界があった。また、吸着材を有効活用する為の空間自由度が限られてしまう為に、吸着可能なガス量に限界があった。   However, in the invention described in Patent Document 1, since the adsorbent is arranged in a limited space inside the battery, there is a limit to the volume for arranging the adsorbent. Further, since the degree of spatial freedom for effectively using the adsorbent is limited, there is a limit to the amount of gas that can be adsorbed.

また、特許文献２に記載の発明は、定常使用状態では、酸素が存在しない密閉空間の体積を小さくし、ガス発生時に酸素が存在しない密閉空間が圧力によって膨らみガスを移動させるというものであり、結局空間が膨張する為の体積を事前に用意しておく必要があった。すなわち、全体の体格が粗大化するため、自動車等の車両への搭載には問題があった。   The invention described in Patent Document 2 is such that, in a steady use state, the volume of the sealed space in which oxygen is not present is reduced, and the sealed space in which oxygen is not present is expanded by pressure when gas is generated, and gas is moved. Eventually, it was necessary to prepare a volume for expanding the space in advance. That is, since the overall physique becomes coarse, there is a problem in mounting on vehicles such as automobiles.

特許文献３に記載の発明は、リチウム電池から放出されるガスの温度が、５００℃以上の高温であるために、イオン交換樹脂では耐熱性が足りずにガス成分を補足しきれないのみならず、放出されるガスの物質が電解液の酸、アルカリ成分だけではなく、正・負極活物質粉塵や正極の集電箔であるアルミニウム、負極の集電箔である銅の粉塵および酸・アルカリでない電解液の分解ガス成分も含まれるため、イオン交換樹脂では補足しきれないという問題があった。
特開平７−１９２７７５号公報 特開２０００−１２０８２号公報 特開平１１−３３９７４７号公報 In the invention described in Patent Document 3, since the temperature of the gas released from the lithium battery is a high temperature of 500 ° C. or higher, the ion exchange resin does not have sufficient heat resistance and cannot fully supplement the gas components. , Not only the acid and alkali components of the electrolyte, but also the positive and negative electrode active material dust, the positive electrode current collector aluminum, the negative electrode current collector copper dust and the acid and alkali Since the decomposition gas component of the electrolytic solution is also included, there is a problem that the ion exchange resin cannot be completely supplemented.

本発明は上記実状に鑑みてなされたものであり、電池のケース外に排出された有色物質粒子により視界が狭窄されることが抑えられた二次電池システムを提供することを課題とする。   This invention is made | formed in view of the said actual condition, and makes it a subject to provide the secondary battery system by which the visual field was suppressed by the colored substance particle | grains discharged | emitted out of the battery case.

上記課題を解決するために本発明者らは二次電池をもつ二次電池システムについて検討を重ねた結果、二次電池から発生した有色物質粒子を除去する有色物質除去手段をもつ二次電池システムとすることで上記課題を解決できることを見出した。   In order to solve the above problems, the present inventors have studied a secondary battery system having a secondary battery, and as a result, a secondary battery system having a colored substance removing means for removing colored substance particles generated from the secondary battery. It has been found that the above problem can be solved.

すなわち、本発明の二次電池システムは、正極および負極が電解液とともにケースに封入された二次電池と、二次電池のケース内の内圧が所定値以上となったときにケースの外部に放出された有色物質粒子を除去する有色物質除去手段を有することを特徴とする。   That is, the secondary battery system of the present invention includes a secondary battery in which a positive electrode and a negative electrode are enclosed in a case together with an electrolyte, and discharges to the outside of the case when the internal pressure of the secondary battery exceeds a predetermined value. It has a colored substance removing means for removing the colored substance particles formed.

本発明の二次電池システムは、有色物質除去手段を有することで、二次電池から排出される有色物質粒子を除去することができる。なお、本発明の二次電池システムにおいて、有色物質粒子とは二次電池のケースの内部から外部にガスとともに排出される粒子を示す。具体的には、有色物質粒子は、電解液の分解生成物、正・負極活物質粉塵等の物質よりなる粒子を示す。   Since the secondary battery system of the present invention has the colored substance removing means, the colored substance particles discharged from the secondary battery can be removed. In the secondary battery system of the present invention, the colored substance particles are particles discharged together with gas from the inside of the secondary battery case to the outside. Specifically, the colored substance particles indicate particles made of a substance such as a decomposition product of the electrolytic solution and positive / negative electrode active material dust.

本発明の二次電池システムは、ケースの外部に放出された有色物質粒子を有色物質除去手段に移送する管路をもつことが好ましい。管路をもつことで、二次電池が排出した有色物質粒子を有色物質除去手段に移送することができ、これにより、もれなく有色物質を除去できるようになる。また、二次電池と有色物質除去手段とを管路で接続することで、二次電池と有色物質除去手段とを離して設置できる。すなわち、二次電池と有色物質除去手段を隣接させたり一体にもうける必要がなくなり、本発明の二次電池システムの設計の自由度が向上する。   The secondary battery system of the present invention preferably has a conduit for transferring the colored substance particles discharged to the outside of the case to the colored substance removing means. By having the pipe line, the colored substance particles discharged from the secondary battery can be transferred to the colored substance removing means, and the colored substance can be removed without any leakage. Further, the secondary battery and the colored substance removing means can be installed separately by connecting the secondary battery and the colored substance removing means with a conduit. That is, it is not necessary to make the secondary battery and the colored substance removing means adjacent to each other or to be provided integrally, and the degree of freedom in designing the secondary battery system of the present invention is improved.

管路は、少なくとも有色物質粒子が放出されるケースの開口部を一端が気密的に被覆することが好ましい。管路の一端が開口部を被覆することで、二次電池が有色物質粒子を排出してもすべての有色物質粒子が管路により有色物質除去手段に移送されることとなり、二次電池システムの外部に有色物質粒子が排出されなくなる。なお、有色物質粒子が放出されるケースの開口部とは、有色物質粒子がケースから放出される部分であればどこでもよい。具体的には、二次電池においてケースにもうけられたガス排出口や、ケースの内圧が上昇してケースが破損して発生した穴をあげることができる。   It is preferable that at least one end of the conduit covers the opening of the case from which the colored substance particles are discharged in an airtight manner. Since one end of the pipe line covers the opening, even if the secondary battery discharges the colored substance particles, all the colored substance particles are transferred to the colored substance removing means by the pipe line. Colored material particles are not discharged to the outside. The opening of the case from which the colored substance particles are released may be any part as long as the colored substance particles are released from the case. Specifically, the gas discharge port provided in the case in the secondary battery and the holes generated by the case internal pressure rising and the case being damaged can be mentioned.

また、管路は、その一端がケースの開口部を気密的に被覆できるのであればその被覆の形態は特に限定されるものではない。すなわち、管路の一端が、その内部に開口部が位置するように周縁部に接続されていても、ケースの全体を収納した状態であっても特に限定されるものではない。   In addition, the form of the pipe is not particularly limited as long as one end of the pipe can cover the opening of the case in an airtight manner. That is, there is no particular limitation even if one end of the pipe line is connected to the peripheral edge so that the opening is located inside the pipe, or even when the entire case is housed.

ケースの開口部は、ケースにもうけられたガス排出口であることがより好ましい。ガス排出口は、ケースの内圧が所定の値以上に上昇したときに開放され、ケースの破損を抑えるための開口部である。ガス排出口は、安全弁等の安全装置を備えたことが好ましい。ケースにあらかじめガス排出口をもうけておくことで、有色物質粒子を含む有色ガスが発生してケース内の圧力が高くなってもガス排出口が開放されることで、ガス排出口以外の部分から有色物質粒子を含む有色ガスが排出されなくなる。内圧の上昇時にケースの破損を抑えることができる。そして、ケースの開口部がガス排出口となることで、二次電池から排出される有色物質粒子を含む有色ガスのすべてが管路を通って有色物質除去手段に移送されることとなる。   More preferably, the opening of the case is a gas outlet provided in the case. The gas discharge port is an opening for opening the case when the internal pressure of the case rises to a predetermined value or more and suppressing damage to the case. The gas outlet preferably includes a safety device such as a safety valve. By providing a gas outlet in the case in advance, even if the colored gas containing colored substance particles is generated and the pressure in the case increases, the gas outlet is opened, so that the gas outlet can be opened from any part other than the gas outlet. Colored gas containing colored substance particles is not discharged. Case damage can be suppressed when the internal pressure increases. And since the opening part of a case becomes a gas discharge port, all the colored gas containing the colored substance particle | grains discharged | emitted from a secondary battery will be transferred to a colored substance removal means through a pipe line.

有色物質除去手段は、有色ガスから有色物質粒子を除去できる手段であれば特に限定されるものではない。有色物質除去手段は、有色物質粒子を吸着する吸着材をもつ吸着手段、有色物質粒子を濾別するフィルタ、有色物質粒子を捕捉するトラップ、から選ばれる少なくともひとつよりなることが好ましい。   The colored substance removing means is not particularly limited as long as it is a means capable of removing the colored substance particles from the colored gas. The colored substance removing means is preferably composed of at least one selected from an adsorbing means having an adsorbing material that adsorbs the colored substance particles, a filter for filtering out the colored substance particles, and a trap for capturing the colored substance particles.

吸着手段は、有色物質粒子を吸着する吸着材を有する。すなわち、吸着材の配置された部分に有色物質粒子を含む有色ガスを通過させ、有色物質粒子を吸着材に吸着させ、外部に排出されたときに視界の妨げとなる有色物質粒子の拡散を抑える。吸着手段において吸着材は、有色物質粒子を吸着することができれば特に限定されるものではない。たとえば、活性炭、ゼオライト等の多孔質材や、カーボン、セラミックス、金属等の粒子を用いることができる。吸着材を構成する多孔質材の細孔容積、細孔径等の特性については、吸着すべき有色物質により異なるため一概に決定できるものではない。   The adsorption means has an adsorbent that adsorbs the colored substance particles. That is, a colored gas containing colored substance particles is allowed to pass through the portion where the adsorbent is disposed, the colored substance particles are adsorbed by the adsorbent, and the diffusion of the colored substance particles that hinder the visibility when discharged to the outside is suppressed. . The adsorbent in the adsorbing means is not particularly limited as long as it can adsorb colored substance particles. For example, porous materials such as activated carbon and zeolite, and particles such as carbon, ceramics, and metal can be used. The characteristics of the porous material constituting the adsorbent, such as the pore volume and the pore diameter, vary depending on the colored substance to be adsorbed and cannot be determined unconditionally.

フィルタは、有色物質粒子を濾別する。すなわち、フィルタに有色物質粒子を含む有色ガスを通過させることで有色物質粒子をフィルタで濾別して除去し、有色ガスから有色物質粒子を取り除く。フィルタは、有色物質粒子を濾別できるものであれば特に限定されるものではない。たとえば、メッシュ状エアフィルタ、ＤＰＦ等の部材をあげることができる。   The filter separates the colored substance particles. That is, by passing a colored gas containing colored substance particles through the filter, the colored substance particles are filtered and removed by the filter, and the colored substance particles are removed from the colored gas. The filter is not particularly limited as long as it can separate colored substance particles. For example, a member such as a mesh air filter or DPF can be used.

トラップは、有色物質粒子をトラップすることで有色物質粒子を有色ガスから除去する。トラップは、有色ガス中の有色物質粒子をトラップすることができる手段であれば特に限定されるものではない。たとえば、有色物質粒子を含む有色ガスを液体に透過させてこの液体に有色物質粒子を溶解させたり分散沈降させるトラップや、有色物質粒子を含む有色ガスに遠心力を付与して有色物質粒子を分離捕捉するトラップ等のトラップをあげることができる。   The trap removes the colored substance particles from the colored gas by trapping the colored substance particles. The trap is not particularly limited as long as it is a means capable of trapping colored substance particles in the colored gas. For example, a colored gas containing colored substance particles is permeated through the liquid to dissolve or disperse the colored substance particles in this liquid, or a centrifugal force is applied to the colored gas containing colored substance particles to separate the colored substance particles. Traps such as traps to be captured can be listed.

有色物質除去手段は、円筒状や角柱状のカラムに充填された吸着材であり、カラムの長さＬとカラムの内径Ｄとの比Ｌ／Ｄが０．５〜２０であることが好ましい。有色物質除去手段が活性炭よりなる吸着材をもつカラムよりなり、Ｌ／Ｄが０．５〜２０となることで、二次電池からの有色物質粒子を取り除くことができる。特に、Ｌ／Ｄが１１以上となると、有色物質粒子を含む有色ガスがカラムを透過するときの圧損が大きくなり、二次電池のケースの内圧が上昇するようになり、場合によってはさらにケースが破裂する。カラムの長さＬとカラムの内径Ｄとの比Ｌ／Ｄは、０．９〜１１であることがより好ましい。   The colored substance removing means is an adsorbent packed in a cylindrical or prismatic column, and the ratio L / D of the column length L to the column inner diameter D is preferably 0.5 to 20. The colored substance removing means comprises a column having an adsorbent made of activated carbon, and the L / D is 0.5 to 20, whereby the colored substance particles from the secondary battery can be removed. In particular, when L / D is 11 or more, the pressure loss when the colored gas containing colored substance particles permeates the column increases, and the internal pressure of the case of the secondary battery increases. Burst. The ratio L / D between the column length L and the column inner diameter D is more preferably 0.9 to 11.

本発明の二次電池システムを構成する二次電池は、充放電を繰り返すことが可能な二次電池であればその種類が特に限定されるものではなく従来公知の二次電池を用いることができる。たとえば、鉛電池、Ｎｉ−Ｃｄ電池、Ｎｉ−水素電池などの電解液に水溶液を用いた二次電池や、リチウム電池などの電解液に有機電解液を用いた二次電池をあげることができる。エネルギー密度が高いことから、二次電池は非水系二次電池であることが好ましい。   The type of secondary battery constituting the secondary battery system of the present invention is not particularly limited as long as it is a secondary battery that can be repeatedly charged and discharged, and a conventionally known secondary battery can be used. . For example, a secondary battery using an aqueous solution as an electrolyte such as a lead battery, a Ni-Cd battery, or a Ni-hydrogen battery, or a secondary battery using an organic electrolyte as an electrolyte such as a lithium battery can be given. Since the energy density is high, the secondary battery is preferably a non-aqueous secondary battery.

また、本発明の二次電池システムを構成する二次電池は、単電池であっても複数の単電池よりなる組電池であってもいずれでもよい。また、一つの電極体がケースに収容された単セル電池であっても、複数の電極体が一つに収容された複数セル電池であってもいずれでもよい。   Further, the secondary battery constituting the secondary battery system of the present invention may be either a single battery or an assembled battery composed of a plurality of single batteries. Further, it may be a single cell battery in which one electrode body is housed in a case, or may be a multiple cell battery in which a plurality of electrode bodies are housed in one.

本発明の二次電池システムは、二次電池からの有色物質粒子を含む有色ガスの有色物質粒子を取り除くことで有色ガスを無色透明化できる。ハイブリッド自動車や電気自動車等の車両へ搭載したときに運転者の視界を有色ガスに含まれる有色物質粒子が妨げなくなっている。すなわち、本発明の二次電池システムは、車載用二次電池システムに用いることが好ましい。   In the secondary battery system of the present invention, the colored gas can be made colorless and transparent by removing the colored substance particles of the colored gas including the colored substance particles from the secondary battery. When mounted on a vehicle such as a hybrid vehicle or an electric vehicle, the colored substance particles contained in the colored gas do not hinder the driver's view. That is, the secondary battery system of the present invention is preferably used for an in-vehicle secondary battery system.

本発明の二次電池システムは、二次電池から排出された有色ガスから有色物質除去手段で有色物質粒子を除去する。これにより、二次電池から外部に放出されるガスが無色透明となる。この結果、二次電池システムの外部に放出されるガスが視野の狭窄を生じさせなくなっている。   In the secondary battery system of the present invention, the colored substance particles are removed from the colored gas discharged from the secondary battery by the colored substance removing means. Thereby, the gas discharged | emitted from a secondary battery outside becomes colorless and transparent. As a result, the gas released to the outside of the secondary battery system does not cause narrowing of the visual field.

以下に、本発明の実施の形態について説明する。本形態の二次電池システムは車両に搭載される二次電池システムであり、二次電池として非水電解液二次電池を、有色物質除去手段にガソリン蒸気を回収する為のキャニスターを利用した。本形態の二次電池システムの構成を図1に示した。なお、以下の本実施形態の二次電池システムの説明は、本発明の二次電池システムと関与しない装置については特に言及しない。特に、ガスが流れる流路にもうけられたバルブ等に関してもその機能が明らかであり、説明しない。   Embodiments of the present invention will be described below. The secondary battery system of this embodiment is a secondary battery system mounted on a vehicle, and a non-aqueous electrolyte secondary battery is used as the secondary battery, and a canister for collecting gasoline vapor is used as the colored substance removing means. The configuration of the secondary battery system of this embodiment is shown in FIG. In addition, the description of the secondary battery system of this embodiment below does not particularly refer to devices that are not related to the secondary battery system of the present invention. In particular, the function of the valve or the like provided in the flow path through which the gas flows is obvious and will not be described.

本実施形態の二次電池システムは、複数の電池１１を組み合わせてなる電池パック１０（本発明の二次電池に相当）とキャニスター２０とをもつ。   The secondary battery system of this embodiment includes a battery pack 10 (corresponding to the secondary battery of the present invention) formed by combining a plurality of batteries 11 and a canister 20.

電池パック１０は、複数の電池１１を有している。本形態を示した図１においては、４つの電池１１が描かれているが、本発明においては、４つの電池に限定されるものではない。また、電池パック１０内には、電池１１から排出される有色ガスをまとめる為の排出ガス回収室１２がある。排出ガス回収室１２は、電池パック１０全体がこの機能を果たしてもよい。排出ガス回収室１２は、図１には電池パック１０内を２分して描かれてあるが、この排出ガス回収室１２の数も２分されることに限定されるわけではない。排出ガス回収室１２に集まった有色ガスは、排出ガスダクト３０を通りキャニスター２０に導入される。キャニスター２０内には、フィルタ２１、トラップ材（活性炭）２２が備えられており、有色ガスがキャニスター２０を透過すると、有色ガス中に含まれる有色物質粒子がフィルタ２１およびトラップ材２２に吸着される。そして、有色ガスから有色物質粒子が取り除かれて車外ガス排出口３３から車体４０の外部に排出される。   The battery pack 10 has a plurality of batteries 11. In FIG. 1 showing this embodiment, four batteries 11 are depicted, but the present invention is not limited to four batteries. The battery pack 10 also has an exhaust gas recovery chamber 12 for collecting colored gases exhausted from the battery 11. In the exhaust gas recovery chamber 12, the entire battery pack 10 may fulfill this function. Although the exhaust gas recovery chambers 12 are depicted by dividing the inside of the battery pack 10 into two in FIG. 1, the number of exhaust gas recovery chambers 12 is not limited to being divided into two. The colored gas collected in the exhaust gas recovery chamber 12 passes through the exhaust gas duct 30 and is introduced into the canister 20. In the canister 20, a filter 21 and a trap material (activated carbon) 22 are provided. When the colored gas passes through the canister 20, the colored substance particles contained in the colored gas are adsorbed by the filter 21 and the trap material 22. . Then, the colored substance particles are removed from the colored gas and discharged from the vehicle gas discharge port 33 to the outside of the vehicle body 40.

本実施形態の二次電池システムは、万が一電池パック１０の電池１１から有色物質粒子を含む有色ガスが発生しても、キャニスター２０によって有色物質粒子を除去して車外に放出できるため、視界が遮られることがなくなり安全性が確保できる。   In the secondary battery system of the present embodiment, even if colored gas containing colored substance particles is generated from the battery 11 of the battery pack 10, the canister 20 can remove the colored substance particles and release them outside the vehicle. Safety can be ensured.

ここで、図１に示した形態において、キャニスター２０の活性炭が充填された部分の長さＬと径Ｄの比Ｌ／Ｄは、３．５であった。そして、長さＬと径Ｄの比Ｌ／Ｄが０．５〜２０の範囲内であれば、この電池パック１０を用いたシステムにおける有色物質粒子の除去を行うことができる。これにより、本実施形態の二次電池システムは、電池１１から有色ガスが発生しても、キャニスター２０を通って有色ガスが排出されることで、電池パック１０の内圧の上昇が抑えられ、電池缶の耐圧限度以下となり、電池缶の破裂が防止可能となる効果も発揮する。   Here, in the form shown in FIG. 1, the ratio L / D of the length L and the diameter D of the portion of the canister 20 filled with activated carbon was 3.5. If the ratio L / D of the length L to the diameter D is in the range of 0.5 to 20, the colored substance particles in the system using the battery pack 10 can be removed. Thereby, even if colored gas generate | occur | produces from the battery 11, the secondary battery system of this embodiment suppresses the raise of the internal pressure of the battery pack 10 by discharging colored gas through the canister 20, and a battery The effect is that the battery can is prevented from rupture because it is below the pressure limit of the can.

図１に示した形態では、現在多くの車両で使用されているキャニスター２０を有色物質粒子の除去に用いている。ここで、有色物質粒子の除去に用いられる装置は、キャニスター２０などの車両に取り付けられている装置ではなく、有色物質粒子を取り除くことができる装置を新たに車両に取り付けて用いてもよい。   In the embodiment shown in FIG. 1, a canister 20 that is currently used in many vehicles is used to remove colored substance particles. Here, the apparatus used for removing the colored substance particles is not an apparatus attached to the vehicle such as the canister 20, but a device capable of removing the colored substance particles may be newly attached to the vehicle.

以下、実施例を用いて本発明を説明する。   Hereinafter, the present invention will be described using examples.

本発明の実施例として、車両に搭載された、二次電池１０と有色物質除去手段２０とを排出ガスダクトで接続した二次電池システムを作製した。   As an example of the present invention, a secondary battery system mounted on a vehicle and connecting the secondary battery 10 and the colored substance removing means 20 with an exhaust gas duct was produced.

The secondary battery system of each of the above examples was evaluated. Specifically, assuming misuse of the lithium ion battery, the lithium ion battery 11 is caused to smoke by continuously energizing a current of 50 A and overcharged, and the colored gas containing colored substance particles generated at this time Was permeated through the colored substance removing means 20, and the gas discharged to the outside of the vehicle body 40 was observed and evaluated. The degree of the effect was confirmed by visual observation through the camera monitor.

このとき、圧カセンサーを二次電池１０と排出ガスダクト３０の接続部に取り付け、二次電池１０の内圧を測定した。このときの有色物質除去手段２０のＬ／Ｄ比とケース１２内の内圧の関係を図３に示した。   At this time, the pressure sensor was attached to the connection part of the secondary battery 10 and the exhaust gas duct 30, and the internal pressure of the secondary battery 10 was measured. The relationship between the L / D ratio of the colored substance removing means 20 and the internal pressure in the case 12 at this time is shown in FIG.

また、比較例として、有色物質除去手段２０を持たない以外は実施例１と同様な構成の二次電池システムも作製し、同様な評価を行った。比較例の二次電池システムに上記過充電をすると、有色物質粒子を含む有色ガスが多量に排出された。   Further, as a comparative example, a secondary battery system having the same configuration as that of Example 1 except that the colored substance removing unit 20 was not provided was also manufactured and evaluated in the same manner. When the secondary battery system of the comparative example was overcharged, a large amount of colored gas containing colored substance particles was discharged.

Further, the internal pressure of the exhaust gas recovery chamber 120 is 0.068 Mpa, that is, it can be seen that the trap effect is higher than that of the first embodiment.

実施例５の二次電池システムにおいては、有色物質除去手段２０からは全くの無煙では無く僅かばかりの煙（有色物質粒子を含む有色ガス）は確認された。また、排出ガス回収室１２０の内圧は、０．０７０Ｍｐａとなり、つまり、実施例１よりもかなり高いトラップ効果があることがわかる。   In the secondary battery system of Example 5, a slight amount of smoke (colored gas containing colored material particles) was confirmed from the colored material removing means 20 instead of no smoke. Further, the internal pressure of the exhaust gas recovery chamber 120 is 0.070 MPa, that is, it can be seen that the trap effect is considerably higher than that of the first embodiment.

実施例６の二次電池システムにおいては、有色物質除去手段２０からは全くの無煙では無く僅かばかりの煙（有色物質粒子を含む有色ガス）は確認された。また、排出ガス回収室１２０の内圧は、０．２８０Ｍｐａとなり、つまり、実施例１よりもかなり高いトラップ効果があることがわかる。   In the secondary battery system of Example 6, a slight amount of smoke (colored gas containing colored material particles) was confirmed from the colored material removing means 20 instead of no smoke. The internal pressure of the exhaust gas recovery chamber 120 is 0.280 Mpa, that is, it can be seen that the trap effect is considerably higher than that of the first embodiment.

実施例７の二次電池システムにおいては、有色物質除去手段２０からは全くの無煙では無く僅かばかりの煙（有色物質粒子を含む有色ガス）は確認された。それでも、実施例５より煙の排出量は少なかった。また、排出ガス回収室１２０の内圧は、０．４８６Ｍｐａとなり、つまり、実施例１よりもかなり高いトラップ効果があることがわかる。   In the secondary battery system of Example 7, a slight amount of smoke (colored gas containing colored material particles) was confirmed from the colored material removing means 20 instead of no smoke. Nevertheless, the amount of smoke emitted was less than in Example 5. Further, the internal pressure of the exhaust gas recovery chamber 120 is 0.486 Mpa, that is, it can be seen that the trap effect is considerably higher than that of the first embodiment.

実施例８の二次電池システムにおいては、有色物質除去手段２０からは全くの無煙では無く僅かばかりの煙（有色物質粒子を含む有色ガス）は確認された。また、排出ガス回収室１２０の内圧は、０．３７８Ｍｐａとなり、つまり、実施例１よりもかなり高いトラップ効果があることがわかる。   In the secondary battery system of Example 8, a slight amount of smoke (colored gas containing colored material particles) was confirmed from the colored material removing means 20 instead of no smoke. Further, the internal pressure of the exhaust gas recovery chamber 120 is 0.378 MPa, that is, it can be seen that the trap effect is considerably higher than that of the first embodiment.

実施例９の二次電池システムにおいては、有色物質除去手段２０からは全くの無煙では無く僅かばかりの煙（有色物質粒子を含む有色ガス）は確認された。それでも、実施例７より煙の排出量は少なかった。しかし、有色物質除去手段２０の内圧があがり、二次電池１０と排出ガスダクト３０の接合部から若干の煙が漏出した。また、排出ガス回収室１２０の内圧は、０．４６８Ｍｐａとなり、つまり、実施例１よりもかなり高いトラップ効果があることがわかる。   In the secondary battery system of Example 9, a slight amount of smoke (colored gas containing colored material particles) was confirmed from the colored material removing means 20 instead of no smoke. Nevertheless, the amount of smoke emitted was less than in Example 7. However, the internal pressure of the colored substance removing means 20 increased, and some smoke leaked from the joint between the secondary battery 10 and the exhaust gas duct 30. In addition, the internal pressure of the exhaust gas recovery chamber 120 is 0.468 Mpa, that is, it can be seen that the trap effect is considerably higher than that of the first embodiment.

実施例１０の二次電池システムにおいては、有色物質除去手段２０からは全くの無煙では無く僅かばかりの煙（有色物質粒子を含む有色ガス）は確認された。また、排出ガス回収室１２０の内圧は、０．４７０Ｍｐａとなり、つまり、実施例１よりもかなり高いトラップ効果があることがわかる。   In the secondary battery system of Example 10, a slight amount of smoke (colored gas containing colored material particles) was confirmed from the colored material removing means 20 instead of no smoke. Moreover, the internal pressure of the exhaust gas recovery chamber 120 is 0.470 MPa, that is, it can be seen that the trap effect is considerably higher than that of the first embodiment.

実施例１１の二次電池システムに上記過充電をすると、リチウムイオン電池１１のケース内の内圧は３Ｍｐａ以上と電池缶の耐圧限度以上の圧力となり電池１１の缶が破裂した。しかしながら、リチウムイオン電池１１のケースが破裂する前には、有色物質除去手段２０からは全くの無煙では無く僅かばかりの煙（有色物質粒子を含む有色ガス）は確認された。つまり、トラップ効果をもつことがわかる。   When the secondary battery system of Example 11 was overcharged, the internal pressure in the case of the lithium ion battery 11 was 3 Mpa or more, which was above the pressure limit of the battery can, and the can of the battery 11 burst. However, before the case of the lithium ion battery 11 ruptured, a slight amount of smoke (colored gas containing colored material particles) was confirmed from the colored material removing means 20 instead of completely smokeless. That is, it turns out that it has a trap effect.

（実施例１２）
本実施例の二次電池システムは、図４にその構成が示された二次電池システムである。 (Example 12)
The secondary battery system of the present embodiment is a secondary battery system whose configuration is shown in FIG.

二次電池１０は、実施例１と同様に、１２Ａｈ級のリチウムイオン電池１１と、リチウムイオン電池１１の一部を被覆するとともに内部に排出ガス回収室１２０を区画するケース１２と、をもつ。なお、リチウムイオン電池１１のケースは、耐圧限界が３Ｍｐａであった。   Similar to the first embodiment, the secondary battery 10 includes a 12 Ah-class lithium ion battery 11 and a case 12 that covers a part of the lithium ion battery 11 and defines an exhaust gas recovery chamber 120 therein. The case of the lithium ion battery 11 had a pressure limit of 3 Mpa.

有色物質除去手段２０は、８リットルの水２４を貯留したタンク２３と、吸着材を持つ吸着手段２５と、をもつ。   The colored substance removing unit 20 includes a tank 23 storing 8 liters of water 24 and an adsorbing unit 25 having an adsorbing material.

排出ガスダクト３０は、その先端部が水２４に浸漬した状態で配置されている。つまり、タンク２３に導入されるガスは、水２４内に導入される。そして、水２４を通過したガスは、排出ガスダクト３２を通って吸着手段２５に導入される。タンク２３は、排出ガスダクト３０，３２を通過する以外でガスが移動しないように密閉されている。   The exhaust gas duct 30 is arranged in a state where the tip end is immersed in the water 24. That is, the gas introduced into the tank 23 is introduced into the water 24. Then, the gas that has passed through the water 24 is introduced into the adsorption means 25 through the exhaust gas duct 32. The tank 23 is sealed so that the gas does not move except through the exhaust gas ducts 30 and 32.

吸着手段２５は、筒状の通路内に吸着材２６を充填し両端を通気性を持つフィルタ２１で封止した構成を有している。この吸着材２６は、活性炭（ＢＣ−９、キャタラー製）を１４ｍｌとモレキュラーシーブ１３Ｘ、関東化学製を１８ｍ１を混合して製造された。吸着手段２５の吸着材２６が充填された部分の長さＬ＝２９ｍｍ、内径はＤ＝３２ｍｍであり、その比Ｌ／Ｄは、０．９０であった。   The adsorbing means 25 has a configuration in which an adsorbent 26 is filled in a cylindrical passage and both ends are sealed with a filter 21 having air permeability. This adsorbent 26 was manufactured by mixing 14 ml of activated carbon (BC-9, manufactured by Cataler) with molecular sieve 13X and 18 ml of manufactured by Kanto Chemical. The length L = 29 mm of the portion filled with the adsorbent 26 of the adsorbing means 25, the inner diameter was D = 32 mm, and the ratio L / D was 0.90.

そして、吸着手段２５を透過したガスは、排出ガスダクト３１を通って車体４０の外部に排出される。   The gas that has permeated through the adsorbing means 25 is discharged to the outside of the vehicle body 40 through the exhaust gas duct 31.

本実施例の二次電池システムに上記した過充電による発煙を生じさせたところ、有色物質除去手段２０からは全くの無煙では無く僅かばかりの煙（有色物質粒子を含む有色ガス）は確認された。そして、実施例１と同等程度の高いトラップ効果があることがわかる。   When the secondary battery system of this example caused the above-described smoke generation due to overcharging, the colored substance removing means 20 confirmed that only a small amount of smoke (colored gas containing colored substance particles) was found. . And it turns out that there exists a high trap effect comparable as Example 1. FIG.

上記各実施例のように、有色物質除去手段２０をもつことで、リチウムイオン電池１１から有色物質粒子を含む有色ガスが発生しても、有色物質除去手段２０によって有色物質粒子を除去して車外に放出できるため、視界が遮られることがなくなるため安全性の高い二次電池システムを新たに提供することができた。   By having the colored substance removing means 20 as in each of the above embodiments, even if colored gas containing colored substance particles is generated from the lithium ion battery 11, the colored substance removing means 20 removes the colored substance particles and the outside of the vehicle. Therefore, the field of view is not obstructed, and a highly safe secondary battery system can be newly provided.
