Description
本発明は、電子機器や自動車等に使用される蓄電デバイスから発生するガス成分の吸収に好適なガス吸収材を提案する方法に関する。 The present invention relates to a method for proposing a gas absorbent suitable for absorbing a gas component generated from an electricity storage device used in electronic devices, automobiles and the like.
近年、例えばリチウムイオン電池、電気二重層キャパシタ、アルミ電解コンデンサ等の大容量、高出力タイプの蓄電デバイスが実用化されている。この蓄電デバイスは、大容量、高出力であるがゆえに従来の蓄電デバイスよりも高い安全性、安定性が求められる。 In recent years, large-capacity, high-output type electricity storage devices such as lithium-ion batteries, electric double layer capacitors, and aluminum electrolytic capacitors have been put into practical use. This electricity storage device is required to have higher safety and stability than conventional electricity storage devices because of its large capacity and high output.
この蓄電デバイスは、一般に正極体及び負極体が電解液とともに筐体内に封入されており、電極シートとセパレータとの積層体を、角型の場合にはサンドイッチ状に、円筒型の場合にはロール状にそれぞれ形成し、集電体としての正極体及び負極体のリード部を各々の端子に接続する。そして、上述したような各種形態の積層体をそれぞれの対応する形状の筐体に収容した後、筐体の開口部から電解液を注入して積層体に電解液を含浸し、正極体及び負極体の先端を外部に露出した状態で筐体に封入した構造を有する。 In this electricity storage device, generally, a positive electrode body and a negative electrode body are enclosed in a casing together with an electrolytic solution, and a laminate of an electrode sheet and a separator is sandwiched in the case of a square type, and rolled in a case of a cylindrical type. And the lead portions of the positive electrode body and the negative electrode body as current collectors are connected to the respective terminals. Then, after accommodating the laminated bodies of various forms as described above in respective correspondingly shaped casings, the electrolytic solution is injected from the opening of the casing to impregnate the laminated body with the electrolytic solution, and the positive electrode body and the negative electrode body. It has a structure in which the body tip is exposed to the outside and enclosed in a casing.
上記蓄電デバイスに用いられる電解液としては、炭酸エチレンなどを含有する非水系電解液が用いられるが、蓄電デバイスのエネルギー密度を向上させるためには使用可能電圧を高めることが有効であることから、特に高い電圧で充放電可能な炭酸エステル系電解液が広く用いられている。 As the electrolytic solution used for the electricity storage device, a non-aqueous electrolyte solution containing ethylene carbonate or the like is used, but since it is effective to increase the usable voltage in order to improve the energy density of the electricity storage device, Particularly, carbonate ester-based electrolytic solutions that can be charged and discharged at a high voltage are widely used.
このような非水系電解液を使用した蓄電デバイスでは、非水系電解液中に含まれる炭酸エステルが長期間の使用における充放電の繰り返し、過充電、あるいは短絡等の異常時の蓄電デバイス内部の温度上昇に起因して、劣化や電気分解をおこす。これにより蓄電デバイス内部でＣＯやＣＯ２などの炭酸ガスやメタン、エタンなどの炭化水素ガスや、その他の非水系電解液ガスに起因したガスが発生し、これにより内圧が上昇して筐体が変形し、内部抵抗が増大する等の不具合を生じる虞があった。そこで、これらのガスを吸収するガス吸収材を蓄電デバイス内に配置することが行われている。 In an electricity storage device using such a non-aqueous electrolyte solution, the carbonic acid ester contained in the non-aqueous electrolyte solution is the temperature inside the electricity storage device during abnormalities such as repeated charge/discharge, overcharge, or short circuit during long-term use. It causes deterioration and electrolysis due to the rise. As a result, carbon dioxide gas such as CO and CO 2 , hydrocarbon gas such as methane and ethane, and gas derived from other non-aqueous electrolyte gas are generated inside the electricity storage device, which increases the internal pressure and There is a risk of deformation and an increase in internal resistance. Therefore, a gas absorbing material that absorbs these gases is arranged in the electricity storage device.
しかしながら、リチウムイオン電池に代表される蓄電デバイスは、日々進化しており、この際には非水系電解液の組成やその他の成分の微妙な変更も行われ、これに伴い発生するガスも変化するため、その都度発生するガスの吸収に好適なガス吸収材を選定することは困難であった。 However, electricity storage devices represented by lithium-ion batteries are evolving day by day, and at this time, the composition of the non-aqueous electrolyte solution and other components are subtly changed, and the gas generated accordingly changes. Therefore, it is difficult to select a gas absorbing material suitable for absorbing the gas generated each time.
本発明は上記課題に鑑みてなされたものであり、電子機器や自動車等に使用される蓄電デバイスから発生するガス成分の吸収に好適なガス吸収材を迅速に提案することが可能な提案方法を提供することを目的とする。 The present invention has been made in view of the above problems, and a proposed method capable of promptly proposing a gas absorbent suitable for absorbing a gas component generated from an electricity storage device used in electronic devices, automobiles, and the like.

（ガス吸収材）
上述したような本実施形態の蓄電デバイス用ガス吸収材の提案方法において、ガス吸収材としては、無機多孔質材料や炭素系材料及び有機無機複合素材を好適に用いることができる。無機多孔質材料としては、多孔質シリカ、金属ポーラス構造体、ケイ酸カルシウム、ケイ酸マグネシウム、メタケイ酸アルミン酸マグネシウム、ゼオライト、活性アルミナ、酸化チタン、アパタイト、多孔質ガラス、酸化マグネシウム、ケイ酸アルミニウム等を用いることができる。ガス吸収材がゼオライトの場合、Ａ型、Ｘ型あるいはＬＳＸ型のゼオライトを用いることがでる。
(Gas absorber)
In the method of proposing the gas absorbent for an electricity storage device of the present embodiment as described above, an inorganic porous material, a carbon-based material, or an organic-inorganic composite material can be preferably used as the gas absorbent. As the inorganic porous material, porous silica, metal porous structure, calcium silicate, magnesium silicate, magnesium metasilicate aluminate, zeolite, activated alumina, titanium oxide, apatite, porous glass, magnesium oxide, aluminum silicate Etc. can be used. When the gas absorbent is zeolite, A-type, X-type or LSX-type zeolite can be used.
また、炭素系材料としては、粉末状活性炭、粒状活性炭、繊維状活性炭、シート状活性炭などの活性炭、グラファイト、カーボンブラック、カーボンナノチューブ、カーボンモレキュラシーブ、フラーレン、ナノカーボン等を用いることができる。 As the carbonaceous material, powdered activated carbon, granular activated carbon, fibrous activated carbon, activated carbon such as sheet activated carbon, graphite, carbon black, carbon nanotube, carbon molecular sieve, fullerene, nanocarbon, etc. can be used.
ガス吸収材が活性炭の場合、活性炭は、一般に細孔径と極性とによって、吸着可能な分子の選択性を有する。したがって、細孔径と極性を調整することによって、ＣＯ２、ＣＯ、メタンガスなどの吸着対象のガス成分に対して好適なものとすることができる。また、細粒状炭素系吸収材は、その表面官能基を調整して極性を付与したものを用いることもできる。この細粒状炭素系吸収材の表面官能基の調整は、細粒状炭素系吸収材を炭酸ガス、窒素ガス又はアルゴンガスで賦活処理を行うことにより行うことができる。具体的には、未処理（初期状態）の細粒状炭素系吸収材の表面は、カルボキシル基やフェノール系水酸基であるが、炭酸ガスで賦活化することにより、その全部または一部を−ＣＨ末端とすることができる。また、ヨウ素や臭素を添着した活性炭を用いることもできる。 When the gas absorbing material is activated carbon, activated carbon generally has selectivity of adsorbable molecules depending on the pore size and the polarity. Therefore, by adjusting the pore size and the polarity, it can be made suitable for the gas components to be adsorbed such as CO 2 , CO, and methane gas. Further, as the fine granular carbon-based absorbent material, a material in which the surface functional group is adjusted to give polarity can be used. The surface functional group of the fine granular carbon-based absorbent can be adjusted by activating the fine granular carbon-based absorbent with carbon dioxide gas, nitrogen gas or argon gas. Specifically, the surface of the untreated (initial state) fine-grained carbon-based absorbent material is a carboxyl group or a phenolic hydroxyl group, but by activating with carbon dioxide gas, all or part of it is -CH-terminated. Can be Alternatively, activated carbon impregnated with iodine or bromine can be used.
これらの無機多孔質材料及び炭素系材料は単独で用いてもよいし、二種類以上の素材を併用してもよい。 These inorganic porous materials and carbonaceous materials may be used alone or in combination of two or more kinds.
以上、本発明の蓄電デバイス用ガス吸収材の提案方法について、添付図面を参照して説明してきたが、本発明は前記実施形態に限定されず種々の変形実施が可能である。例えば、蓄電デバイスとしては、リチウムイオン電池、電気二重層キャパシタ、アルミ電解コンデンサなど種々のものに適用可能であり、その形状なども制限されるものではない。さらに、上記実施形態においては、クラウドＣを介してガス吸収材を選定したが、電子端末Ｉで直接判断するようにしてもよい。 Although the method for proposing the gas absorbent for an electricity storage device of the present invention has been described above with reference to the accompanying drawings, the present invention is not limited to the above-described embodiment, and various modifications can be made. For example, the electricity storage device can be applied to various types such as a lithium ion battery, an electric double layer capacitor, and an aluminum electrolytic capacitor, and the shape thereof is not limited. Furthermore, in the above-described embodiment, the gas absorbing material is selected via the cloud C, but the electronic terminal I may directly determine.
