Description

本発明は熱暴走しないリチウムイオンバッテリ装置に関する。   The present invention relates to a lithium ion battery device that does not run out of heat.

近年、ボーイング７８７の飛行停止命令が問題となっている。この事故では、積載しているリチウムイオンバッテリにその原因があることが分かった。リチウムイオンバッテリが熱暴走を起こし、発火するということである。   In recent years, the flight stop command of Boeing 787 has become a problem. In this accident, it was found that the cause was in the loaded lithium-ion battery. This means that the lithium-ion battery will run out of heat and ignite.

今までのリチウムイオンバッテリは、熱暴走が起きるという重大な問題があった。本発明はこのような課題に鑑みてなされたものであって、リチウムバッテリが熱暴走を起こさず安全に作動させることができるリチウムイオンバッテリ装置を提供することを目的としている。   Conventional lithium-ion batteries have had a serious problem of thermal runaway. This invention is made | formed in view of such a subject, Comprising: It aims at providing the lithium ion battery apparatus which a lithium battery can operate | move safely, without raise | generating a thermal runaway.

リチウムイオンバッテリが熱暴走をしないように配置したことを特徴とする。 Wherein the lithium ion battery is disposed so as not to thermal runaway.

リチウムイオンバッテリが接触しないようにしたので、リチウムイオンバッテリを安全に動作させることができる。   Since the lithium ion battery is not in contact, the lithium ion battery can be operated safely.

本発明の実施例１を示す図The figure which shows Example 1 of this invention 本発明の実施例２を示す図The figure which shows Example 2 of this invention 本発明の実施例３を示す図The figure which shows Example 3 of this invention 本発明の実施例４を示す図The figure which shows Example 4 of this invention

以下、図面を参照して本発明の動作を詳細に説明する。
図１は本発明の実施例１を示す図である。図において、１はリチウムイオンバッテリを収納する収納箱、２は該収納箱１に収納された例えば＃１〜＃８までの８個のリチウムイオンバッテリである。収納箱１としては、頑丈な箱がよい。図では８個までしか示されていないが、収納するバッテリの数は任意でよい。 Hereinafter, the operation of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram showing Embodiment 1 of the present invention. In the figure, 1 is a storage box for storing lithium ion batteries, and 2 is, for example, eight lithium ion batteries # 1 to # 8 stored in the storage box 1. The storage box 1 is preferably a sturdy box. Although only eight are shown in the figure, the number of batteries to be stored may be arbitrary.

このように構成された装置において、隣り合うバッテリ同志の間隔Ｗは、一つのバッテリが発熱しても隣のバッテリが熱伝導しないような空間Ｗが設けられている。従って、あるバッテリが発熱しても隣のバッテリが接触しないので、接触して熱膨張事故を起こすことはない。航空機用のリチウムイオンバッテリにおいて、成層圏を飛行するので、この冷気をバッテリ間のＷに通せばバッテリが冷やされ、あるバッテリが高温のために膨張して隣のバッテリと接触して熱暴走を起こし、発火するという最悪の事態を避けることができる。 In a device constituted as above, the spacing W of the battery the aspirations Adjacent one space W such as next to the battery does not heat conductivity even battery to generate heat are provided. Therefore, since no contact is next to the battery even if there battery fever, it does not cause thermal expansion accident in contact. In the lithium ion battery for an aircraft, since the flight stratosphere, this cold air battery if passed to W between the battery cooled, the contact with the thermal runaway with neighboring battery expands to a certain battery is hot You can avoid the worst of waking up and catching fire.

図２は本発明の実施例２を示す図である。図１と同一のものは、同一の符号を付して示す。この実施例は、リチウムイオンバッテリ２が収納される収納箱１に、クッションとしての機能と、断熱材としての機能を有する断熱材３を充填したものである。このようにすれば、バッテリ同志が衝撃で接触することはなく、また衝撃を断熱材３で吸収するので、バッテリ２が接触して熱暴走を起こし、発火することを防止することができ、高熱が隣のバッテリに伝わることもない。なお、バッテリ２の数は任意でよいことはいうまでもない。 FIG. 2 is a diagram showing a second embodiment of the present invention. The same components as those in FIG. 1 are denoted by the same reference numerals. In this embodiment, a storage box 1 in which a lithium ion battery 2 is stored is filled with a heat insulating material 3 having a function as a cushion and a function as a heat insulating material. In this way, the batteries do not come into contact with each other due to the impact, and the impact is absorbed by the heat insulating material 3 , so that it is possible to prevent the battery 2 from coming into contact and causing a thermal runaway and igniting. Is not transmitted to the next battery. Needless to say, the number of the batteries 2 may be arbitrary.

図３は本発明の実施例３を示す図である。図１と同一のものは、同一の符号を付して示す。図に示す実施例は、各リチウムイオンバッテリに２に主として上下方向の衝撃吸収用のスプリング４を取り付けたものである。スプリング４は各バッテリごとにバッテリ２と収納箱１との間に設けられる。
このように構成すれば、バッテリ同志が離れているので、お互いに熱伝導することなくまた熱膨張しても他のバッテリを傷めることがない上、衝撃により、リチウムイオンバッテリ２に加わる力はスプリング４により吸収される。従って、リチウムイオンバッテリ２が飛行機の離着陸時に衝撃を受けたり、バッテリが隣同志接触して熱膨張を起こし発火する事故を防ぐことができる。 FIG. 3 is a diagram showing a third embodiment of the present invention. The same components as those in FIG. 1 are denoted by the same reference numerals. In the embodiment shown in the figure, a spring 4 for absorbing impact mainly in the vertical direction is attached to each lithium ion battery 2. Spring 4 is provided between the battery 2 and the storage box 1 for each battery.
According to this structure, the battery comrades are separated, on never damage the still another battery even when thermal expansion without thermal conduction to each other by an impact, applied to the lithium ion battery 2 forces Absorbed by the spring 4. Therefore, it is possible to prevent the lithium ion battery 2 or shocked takeoff and landing of the airplane, an accident in which the battery is ignited undergoes thermal expansion in contact next to each other.

図４は本発明の実施例４を示す図である。図１〜図３と同一のものは同一の符号を付して示す。この実施例は、収納箱１に収納されているリチウムイオンバッテリ２の内箱５内に断熱材３でバッテリ２を囲み、この内箱５に衝撃吸収用のスプリング４を取り付けたものである。スプリング４は、前記内箱５と収納箱１との間に取り付けられている。
このように構成すれば、断熱材３によってバッテリ２の一つが発熱しても、他のバッテリを加熱することなくまた、一つのバッテリが熱により膨張しても、他のバッテリを圧迫して変形させることがなく、また離着陸時の衝撃によりバッテリ同志が接触することはなく、また大きな衝撃はスプリング４で吸収することができる。従って、この実施例によれば熱や膨張や衝撃によるあらゆる事故からリチウムイオンバッテリ２を保護することができ、また熱暴走も起こらない。 FIG. 4 is a diagram showing a fourth embodiment of the present invention. 1 to 3 are denoted by the same reference numerals. In this embodiment, a battery 2 is surrounded by a heat insulating material 3 in an inner box 5 of a lithium ion battery 2 stored in a storage box 1, and an impact absorbing spring 4 is attached to the inner box 5. The spring 4 is attached between the inner box 5 and the storage box 1.
If constituted in this way, even if one of the batteries 2 generates heat by the heat insulating material 3 , it does not heat the other battery, and even if one battery expands due to heat, the other battery is pressed and deformed. In addition, the batteries do not come into contact with each other due to an impact during take-off and landing, and a large impact can be absorbed by the spring 4. Therefore, according to this embodiment, the lithium ion battery 2 can be protected from any accidents caused by heat, expansion and impact, and thermal runaway does not occur.

本発明は、バッテリから駆動されるあらゆるものに利用することができ、熱暴走しないリチウムイオンバッテリを得ることができ、航空機事故を起こさずに安全に運航することができる。従って、産業上の利用可能性が大である。   INDUSTRIAL APPLICABILITY The present invention can be used for everything that is driven from a battery, can obtain a lithium ion battery that does not run out of heat, and can operate safely without causing an aircraft accident. Therefore, industrial applicability is great.
