It will occur. If it does so, not only wrinkles etc. will arise in an insulating film but the proximity | contact arrangement | positioning of a some battery will be inhibited.
そこで本発明は、電池ケースの平面部とコーナー部との境界又はその付近において、絶縁フィルムと電池ケースとの間に隙間が生じないようすることをその主たる所期課題とするものである。 Accordingly, the main object of the present invention is to prevent a gap from being formed between the insulating film and the battery case at or near the boundary between the flat portion and the corner portion of the battery case.
すなわち本発明に係る電池は、電池ケースの外側面が、平面部及び当該平面部の端部に形成されて前記平面部から湾曲又は傾斜したコーナー部を有しており、前記電池ケースの外側面に設けられた絶縁フィルムの端部が、前記平面部と平行な方向を向いていることを特徴とする。 That is, in the battery according to the present invention, the outer surface of the battery case has a flat portion and a corner portion that is formed at an end portion of the flat portion and is curved or inclined from the flat portion. The end part of the insulating film provided on the surface is directed in a direction parallel to the flat part.
前記絶縁フィルムが、前記平面部及び前記コーナー部の境界よりもコーナー部側に延出している延出部を有し、前記延出部は、前記コーナー部との間に間隙を形成していることが望ましい。 The insulating film has an extending part that extends to the corner part side with respect to the boundary between the flat part and the corner part, and the extending part forms a gap between the corner part.

It is possible to prevent a gap from being formed between the side surfaces. Thereby, wrinkles or the like generated in the insulating film can be prevented, and a plurality of batteries can be easily arranged close to each other.
以下に本発明に係る電池の一実施形態について図面を参照して説明する。 Hereinafter, an embodiment of a battery according to the present invention will be described with reference to the drawings.
本実施形態の電池１は、例えば自動車に搭載される蓄電装置を構成するリチウムイオン二次電池である。なお、蓄電装置は、１つの電池１を用いて構成されたものであっても良いし、複数の電池を組み合わせて構成されたものであっても良い。 The battery 1 of the present embodiment is a lithium ion secondary battery that constitutes a power storage device mounted on an automobile, for example. The power storage device may be configured using one battery 1 or may be configured by combining a plurality of batteries.
具体的にこの電池１は、図１及び図２に示すように、内部に発電要素（不図示）が収容された電池ケース２と、当該電池ケース２の外側面に配置される絶縁フィルム３とを有する。なお、図２は、絶縁フィルム３を取り外した状態の電池１を示している。 Specifically, as shown in FIGS. 1 and 2, the battery 1 includes a battery case 2 in which a power generation element (not shown) is accommodated, and an insulating film 3 disposed on the outer surface of the battery case 2. Have FIG. 2 shows the battery 1 with the insulating film 3 removed.
電池ケース２は、概略直方体形状をなすものであり、平面視において長手方向及び短手方向を有する扁平形状をなすものである。そして、この電池ケース２は、正極端子Ｔ１及び負極端子Ｔ２が設けられた端子設置面である上面２ａと、この上面２ａの四辺それぞれに連続して設けられた４つの側面２ｂ〜２ｅと、これら４つの側面２ｂ〜２ｅの下端に連続する下面２ｆとを有する。なお、この下面２ｆは、前記端子設置面２ａに対向する面である。 The battery case 2 has a substantially rectangular parallelepiped shape, and has a flat shape having a longitudinal direction and a short direction in plan view. And this battery case 2 has the upper surface 2a which is a terminal installation surface in which the positive electrode terminal T1 and the negative electrode terminal T2 were provided, four side surfaces 2b-2e provided continuously on each of the four sides of the upper surface 2a, and these It has a lower surface 2f continuous to the lower ends of the four side surfaces 2b to 2e. The lower surface 2f is a surface facing the terminal installation surface 2a.
そして、この電池ケース２の外側面である４つの側面２ｂ〜２ｅはそれぞれ、図１に示すように、平面部２１と、当該平面部２１の下端部に連続して形成されて前記平面部２１から湾曲して形成されたコーナー部２２（以下、ラウンド部２２という。）とを有する。このラウンド部２２は、各側面２ｂ〜２ｅと下面２ｆとの間にそれぞれ形成されている。 The four side surfaces 2b to 2e, which are the outer surfaces of the battery case 2, are respectively formed continuously with the flat surface portion 21 and the lower end portion of the flat surface portion 21 as shown in FIG. And a corner portion 22 (hereinafter, referred to as a round portion 22) that is curved. The round portion 22 is formed between each of the side surfaces 2b to 2e and the lower surface 2f.
絶縁フィルム３は、絶縁性及び難燃性を有する樹脂フィルムであり、電池ケース２の外側面である４つの側面２ｂ〜２ｅを被覆するものである。なお、この絶縁フィルム３は、例えば４つの側面２ｂ〜２ｅに巻回されるシート状をなすものである。 The insulating film 3 is a resin film having insulating properties and flame retardancy, and covers the four side surfaces 2 b to 2 e that are the outer surfaces of the battery case 2. In addition, this insulating film 3 makes the sheet shape wound, for example on the four side surfaces 2b-2e.
しかして本実施形態の電池１においては、特に図３に示すように、電池ケース２の外側面２ｂ〜２ｅに設けられた絶縁フィルム３の下端部が、平面部２１と平行な方向を向いている。一方、絶縁フィルム３の上端部は、電池ケース２の上面２ａと面一又はその上側に位置している。つまり、絶縁フィルム３における各側面２ｂ〜２ｅに設けられた部分それぞれが、断面視において、各側面２ｂ〜２ｅの平面部２１と平行な方向な直線形状をなしている。なお、図３において、電池ケース２内部の発電要素は省略している。 Therefore, in the battery 1 of the present embodiment, as shown particularly in FIG. 3, the lower end portion of the insulating film 3 provided on the outer side surfaces 2 b to 2 e of the battery case 2 faces in a direction parallel to the plane portion 21. Yes. On the other hand, the upper end portion of the insulating film 3 is positioned flush with or above the upper surface 2 a of the battery case 2. That is, each part provided in each side surface 2b-2e in the insulating film 3 has comprised the linear shape in the direction parallel to the plane part 21 of each side surface 2b-2e in sectional view. In FIG. 3, power generation elements inside the battery case 2 are omitted.
また、本実施形態の絶縁フィルム３の下端部は、平面部２１及びラウンド部２２の境界２Ｒよりもコーナー部２２側である下側に延出している延出部３１を有している。 Moreover, the lower end part of the insulating film 3 of this embodiment has the extension part 31 extended to the lower side which is the corner part 22 side rather than the boundary 2R of the plane part 21 and the round part 22.
この延出部３１の先端部３１ａは、前記平面部２１及びラウンド部２２の境界２Ｒと前記電池ケース２の下面２ｆを含む平面との間に位置するように構成されている。このように下面２ｆから絶縁フィルム３がはみ出ない構造にすることで、電池１を置いた場合に絶縁フィルム３により電池１が傾いてしまうことを防ぐことができる。より具体的には、電池１の下面２ｆ全体が載置面に接する状態となり、安定した姿勢で電池１を配置することができる。また、絶縁フィルム３が載置面に接することにより折れて、電池１の近接配置を阻害してしまうことを防止できる。この延出部３１は、前記ラウンド部２２に沿って湾曲することなく、前記平面部２１に沿った状態で平面部２１と平行な方向を向き、前記ラウンド部２２の湾曲面との間に間隙Ｓを形成する構成としている。 The distal end portion 31 a of the extending portion 31 is configured to be located between the boundary 2 </ b> R between the flat surface portion 21 and the round portion 22 and a flat surface including the lower surface 2 f of the battery case 2. As described above, the structure in which the insulating film 3 does not protrude from the lower surface 2f can prevent the battery 1 from being inclined by the insulating film 3 when the battery 1 is placed. More specifically, the entire lower surface 2f of the battery 1 is in contact with the placement surface, and the battery 1 can be disposed in a stable posture. Moreover, it can prevent that the insulating film 3 breaks when it contacts a mounting surface, and obstructs the proximity | contact arrangement | positioning of the battery 1. FIG. The extending portion 31 is not curved along the round portion 22, faces in a direction parallel to the planar portion 21 in a state along the planar portion 21, and is spaced from the curved surface of the round portion 22. S is formed.
さらに、絶縁フィルム３は、前記電池ケース２の平面部２１に接着剤により接着されており、延出部３１は、ラウンド部２２に接着されることなくラウンド部２２から離間している。 Furthermore, the insulating film 3 is bonded to the flat portion 21 of the battery case 2 with an adhesive, and the extending portion 31 is separated from the round portion 22 without being bonded to the round portion 22.
このように構成した本実施形態に係る電池１によれば、絶縁フィルム３の下端部を平面部２１と平行な方向を向くように構成して、絶縁フィルム３をコーナー部２２に沿って湾曲させないので、絶縁フィルム３と電池ケース２の外側面２ｂ〜２ｅとの間に隙間を生じないようにすることができる。これにより、絶縁フィルム３に生じる皺等を防止することができ、複数の電池１を近接配置し易くできる。 According to the battery 1 according to the present embodiment configured as described above, the lower end portion of the insulating film 3 is configured to face the direction parallel to the plane portion 21, and the insulating film 3 is not curved along the corner portion 22. Therefore, it is possible to prevent a gap from being generated between the insulating film 3 and the outer side surfaces 2b to 2e of the battery case 2. Thereby, the wrinkles etc. which arise in the insulating film 3 can be prevented, and the some battery 1 can be arrange | positioned near easily.
また、絶縁フィルム３の端部が、平面部２１及びラウンド部２２の境界２Ｒよりもラウンド部２２側に延出している延出部３１を有しており、この延出部３１が、ラウンド部２２との間に間隙Ｓを形成しているので、互いに隣接する電池１間の絶縁距離を長くすることができる。さらに、空冷により電池を冷却する場合には、前記隙間Ｓが形成されているので、コーナー部２２に冷却風が当たり易くなり、冷却効率を向上させることができる。 Moreover, the end part of the insulating film 3 has an extending part 31 that extends to the round part 22 side from the boundary 2R between the flat part 21 and the round part 22, and the extending part 31 is a round part. Since the gap S is formed between the adjacent batteries 1, the insulation distance between the adjacent batteries 1 can be increased. Furthermore, when the battery is cooled by air cooling, since the gap S is formed, the cooling air can easily hit the corner portion 22 and the cooling efficiency can be improved.
その上、絶縁フィルム３が、電池ケース２の平面部２１に接着されているので、絶縁フィルム３と電池ケース２とを密着させることができ、電池ケース２と絶縁フィルム３外部との間の熱伝導効率を向上させることができる。これにより、電池１の冷却又は加熱が容易となる。 In addition, since the insulating film 3 is bonded to the flat portion 21 of the battery case 2, the insulating film 3 and the battery case 2 can be brought into close contact with each other, and heat between the battery case 2 and the outside of the insulating film 3 can be obtained. The conduction efficiency can be improved. Thereby, cooling or heating of the battery 1 becomes easy.
なお、本発明は前記実施形態に限られるものではない。 The present invention is not limited to the above embodiment.
例えば、前記実施形態の電池１を用いた蓄電装置１０が、図４及び図５に示すように、前記実施形態の１又は複数の電池１と、この電池１と熱結合される熱交換部４と、電池１及び熱交換部４の間に設けられた柔軟性を有する熱伝達部材５とを有する構成としても良い。 For example, as shown in FIGS. 4 and 5, the power storage device 10 using the battery 1 of the embodiment includes one or more batteries 1 of the embodiment and a heat exchange unit 4 that is thermally coupled to the battery 1. And a heat transfer member 5 having flexibility provided between the battery 1 and the heat exchange unit 4 may be used.
熱交換部４は、前記電池１の下面２ｆに配置されるものであり、例えば内部に冷却用液体を流通させる冷却用液体流路が形成された冷却プレートである。また、熱伝達部材５は、柔軟性及び熱伝達性を有するゲル状のものであり、例えば熱伝達性の良好なグリス等が考えられる。この熱伝達部材５は、前記冷却プレート４の電池載置面４ａ全体に配置されている。そして、この熱伝達部材５上に前記１又は複数の電池１が載置される。このとき、絶縁フィルム３がラウンド部２２を覆わない構成なので、電池１を熱伝達部材５に載置させると、熱伝達部材５が変形してラウンド部２２に直接接触し（図５参照）、電池ケース２及び熱伝達部材５の接触面積を大きくすることができる。これにより、電池１の冷却効率を向上させることができる。なお、熱交換部４としては、前記冷却プレートに限られず、電池１を加熱する用途の場合には、例えば内部に加熱用液体を流通さえる加熱用液体流路が形成された加熱プレートを用いることが考えられる。この場合には、電池１の加熱効率を向上させることができる。 The heat exchanging part 4 is disposed on the lower surface 2f of the battery 1, and is a cooling plate in which a cooling liquid flow path for circulating a cooling liquid is formed, for example. Further, the heat transfer member 5 is a gel-like member having flexibility and heat transfer, and for example, grease having good heat transfer is conceivable. The heat transfer member 5 is disposed on the entire battery mounting surface 4 a of the cooling plate 4. The one or more batteries 1 are placed on the heat transfer member 5. At this time, since the insulating film 3 does not cover the round part 22, when the battery 1 is placed on the heat transfer member 5, the heat transfer member 5 is deformed and directly contacts the round part 22 (see FIG. 5). The contact area between the battery case 2 and the heat transfer member 5 can be increased. Thereby, the cooling efficiency of the battery 1 can be improved. The heat exchanging unit 4 is not limited to the cooling plate, and in the case of using the battery 1 for heating, for example, a heating plate in which a heating liquid channel for circulating the heating liquid is formed is used. Can be considered. In this case, the heating efficiency of the battery 1 can be improved.
また、前記実施形態のコーナー部２２は、平面部２１から湾曲して形成されたラウンド部であったが、平面部２１から屈曲して傾斜したものであっても良い。 Moreover, although the corner part 22 of the said embodiment was a round part formed by curving from the plane part 21, it may be bent and inclined from the plane part 21.
さらに、前記実施形態では、絶縁フィルム３の端部が平面部２１及びラウンド部（コーナー部）２２の境界２Ｒからラウンド部２２側に延出した構成であったが、図６に示すように、絶縁フィルム３の端部が、延出部３１を有さずに、前記平面部２１及びラウンド部２２の境界２Ｒに端部が位置する構成としても良い。これならば、前記実施形態に比べて電池間の絶縁性は劣ってしまうが、絶縁フィルム３の下端部が平面部２１に接着される構成とされるので、延出部３１がある場合に比べて、絶縁フィルム３と電池ケース２との剥離を防止することができる。また、延出部３１が無いので、熱伝達部材５状に電池１を載置した場合に、当該熱伝達部材５が電池ケース２のラウンド部２２に接触しやすくなる。 Furthermore, in the said embodiment, although the edge part of the insulating film 3 was the structure extended from the boundary 2R of the plane part 21 and the round part (corner part) 22 to the round part 22 side, as shown in FIG. The end portion of the insulating film 3 may be configured such that the end portion is located at the boundary 2 </ b> R between the planar portion 21 and the round portion 22 without having the extending portion 31. If this is the case, the insulation between the batteries is inferior to that of the above embodiment, but the lower end portion of the insulating film 3 is bonded to the flat portion 21, so that compared to the case where the extending portion 31 is present. Thus, peeling between the insulating film 3 and the battery case 2 can be prevented. Moreover, since there is no extension part 31, when the battery 1 is mounted in the shape of the heat transfer member 5, the heat transfer member 5 easily comes into contact with the round part 22 of the battery case 2.
さらに、前記実施形態では、電池ケースの下端部に形成されたコーナー部及び絶縁フィルムに対して本発明を適用した場合について説明したが、電池ケースの端子設置側、つまり上端側に形成されたコーナー部及び絶縁フィルムに対して本発明を適用しても良い。 Further, in the above embodiment, the case where the present invention is applied to the corner portion and the insulating film formed at the lower end portion of the battery case has been described. However, the corner formed at the terminal installation side of the battery case, that is, the upper end side. You may apply this invention with respect to a part and an insulating film.
前記熱伝達部材はゲル状のものとしたが、電池ケースの底面及びコーナー部に接触するものであれば、固体であっても液体であっても良い。また、絶縁フィルムは電池の上面又は下面からはみ出していても良い。 The heat transfer member is a gel, but may be solid or liquid as long as it contacts the bottom and corners of the battery case. Moreover, the insulating film may protrude from the upper surface or the lower surface of the battery.
その上、前記実施形態では、角形電池について説明したが、円形電池に適用可能であることは言うまでも無い。また、本発明は、キャパシタやコンデンサ等の蓄電素子にも適用可能である。 In addition, in the above-described embodiment, the rectangular battery has been described, but it is needless to say that the present invention can be applied to a circular battery. The present invention can also be applied to power storage elements such as capacitors and capacitors.
その他、本発明は前記実施形態に限られず、その趣旨を逸脱しない範囲で種々の変形が可能である。 In addition, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
