It is divided into an exhaust duct 60 that exhausts the gas discharged from the portion 8a to the outside of the case 20.
- the open part 8 a of the unit cell 100 communicates with the exhaust duct 60 through the opening 30 a formed in the flat plate 30.
- the exhaust duct 60 is a first space 61 formed between the partition wall 40 and the flat plate 30 by the partition wall 40 disposed between the flat plate 30 and the exterior plate (lid) 21 of the case 20. And a second space 62 formed between the partition wall 40 and the exterior plate 21 of the case 20, and the first space 61 is inserted into the first space 61 through a through hole 40 a formed in the partition wall 40.

- the “flat plate 30” in the present invention is not necessarily limited to a flat plate, and may be a flat plate as a whole even if there are irregularities or the like according to the shape of the battery case 7, for example.
- the “sealed state” in the present invention does not necessarily mean a completely sealed state, but also includes a sealed state in which a gas that does not have an influence returns from the exhaust duct 60 to the housing unit 50.
- the gas discharged from the open part 8 a of the unit cell 100 to the exhaust duct 60 undergoes adiabatic expansion in the exhaust duct 60, thereby lowering the gas temperature.
- the gas discharged from the open part 8a of the unit cell 100 may be 1000 ° C. or higher, unless the temperature of the adiabatic expansion gas is lowered to a temperature at which it does not react with oxygen, the periphery of the discharged gas Reacts with oxygen present in the atmosphere, may ignite.
- the temperature drop due to adiabatic expansion depends on the volume of the exhaust duct. Further, since the gas discharged to the exhaust duct is discharged outside the case 20 while pushing out oxygen in the exhaust duct, the amount of gas that reacts with oxygen during adiabatic expansion and burns is determined by the volume of the exhaust duct (oxygen). Depending on the amount). Therefore, in order to prevent the gas discharged from the open part 8a of the unit cell 100 from reacting with oxygen and causing continuous combustion, a temperature at which the gas does not react with oxygen by adiabatic expansion in an exhaust duct having a volume as small as possible. Must be reduced to For that purpose, it is necessary to regulate the volume of the exhaust duct in the vicinity of the open portion 8a of the unit cell 100 from which high-temperature gas is discharged.
- the first space 61 in the present invention is provided for such restriction, and the volume of the first space 61 is such that the high-temperature gas discharged from the open portion 8a of the unit cell 100 is the first. After being discharged into the first space 61 by adiabatic expansion, the temperature of the gas when discharged from the first space 61 into the second space 62 is adjusted to be equal to or lower than the temperature at which it does not react with oxygen.
- the volume of the first space 61 can be adjusted as appropriate in consideration of the performance of the unit cell 100 to be used, the type of electrolyte (the type of gas generated), and the like. Further, the volume of the first space 61 that is equal to or lower than the predetermined temperature may be obtained using simulation using a model of adiabatic expansion or may be obtained from various experiments. For example, if an example of a simple experiment is given, a space with a certain volume is provided in the open part 8a of the unit cell 100, and a discharge port from this space to the atmosphere is further provided. Then, a nail is pierced into the battery case 7 of the unit cell 100 to generate an internal short circuit, and high temperature gas is ejected from the open portion 8a. Gas will spout from the outlet while raising sparks and flames, but by selecting the volume of the space, it becomes a fire-extinguishing white smoke-like gas. Thereby, the volume of the first space 61 can be determined.
- the first space 61 communicates with the second space 62 through the through hole 40a in which the partition wall 40 is formed. Therefore, the path through which the high-temperature gas discharged from the open portion 8a of the unit cell 100 passes from the first space 61 to the second space 62 is restricted by the position where the through hole 40a is provided. Therefore, the volume of the first space 61 may be adjusted in consideration of the position where the through hole 40a is provided.
- the space 61 is not shown in the left-right direction in the drawing, but is a space that is not open but closed.
- the path through which the high-temperature gas discharged from the open portion 8a of the unit cell 100 passes from the first space 61 to the second space 62 is mostly the path indicated by the arrow. . Therefore, it is considered that the first space 61 is substantially regulated by the space in the range indicated by A.
- the through holes 40 a are formed at a pitch wider than the pitch in which the unit cells 100 are arranged, the high-temperature gas discharged from the open portions 8 a of the unit cells 100.
- the first space 61 is essentially a space in the range indicated by B. It is thought that it is done.
- the volume of the first space 61 can be substantially restricted by the position where the through hole 40a is provided. However, as shown in FIG.
- the volume of the first space 61 can also be regulated by further dividing the subspace 63.
- the restriction of the first space 61 described above is not strictly determined, and the exhaust duct 60 is partitioned into the first space 61 and the second space 62 and communicates with the open portion 8a of the unit cell 100.
- the volume of the first space 61 By adjusting the volume of the first space 61, the effective operation and effect of the present invention can be exhibited.
- the gas discharged from the first space 61 is discharged to the outside of the case 20 from the second space 62 after being discharged into the second space 62 by adiabatic expansion.
- the volume of the gas is adjusted so that the temperature of the gas is equal to or lower than a temperature at which no trouble occurs even if the gas is discharged out of the case. Since the gas discharged from the first space 61 to the second space 62 is at a temperature that does not react with oxygen by the first space 61, the gas is ignited in the second space 62. It is not. Therefore, unlike the first space 61, the second space 62 does not require adiabatic expansion with a volume as small as possible, and allows a relatively large volume compared to the first space. Further, by using a material having good thermal conductivity such as aluminum or iron for the exterior plate 21 or the partition wall 40, in addition to the temperature decrease due to adiabatic expansion, the effect of temperature decrease due to heat conduction can be added.
- the exhaust duct 60 is partitioned into the first space 61 and the second space 62.
- a plurality of exhaust ducts 60 are provided. These partitions may be used to partition into three or more spaces.
- the second space 62 is not necessarily formed between the partition wall 40 and the exterior plate 21 of the case 20.
- the second partition wall is arranged between the partition wall 40 and the exterior plate 21. And may be formed between the partition wall 40 and the second partition wall.
- the space formed between the second partition and the exterior plate may be a flow path through which a refrigerant or the like flows. Thereby, the temperature of the gas in the 2nd space 62 can be reduced more efficiently.
- the open part 8a of the unit cell 100 was formed in the protrusion part (flat part or side part) of the positive electrode terminal 8
- the flat plate 30 is disposed on the negative electrode terminal side of the unit cell 100, and the exhaust duct 60 is formed between the flat plate 30 and the bottom of the case 20.

Abstract
Description
図1は、本発明の第1の実施形態における電池モジュールに使用する電池100の構成を模式的に示した断面図である。なお、本発明の電池モジュールに使用する電池は、ノート型パソコン等の携帯用電子機器の電源として単体でも使用できる電池であってもよい(以下、電池モジュールに使用する電池を、「素電池」と呼ぶ)。この場合、高性能の汎用電池を、電池モジュールの素電池として使用することができるため、電池モジュールの高性能化、低コスト化をより容易に図ることができる。
第1の実施形態では、図2に示したように、排気ダクト60は、複数の素電池100の一端側(正極端子側または負極端子側)に配設された平板によって、収容部50と区画されている。これは、ケース20内に、複数の素電池100を、その極性を同一方向に揃えて配列した態様によるものである。
第1の実施形態において、素電池100を収容する収容部50と、素電池100の開放部8aから排出されるガスを排気する排気ダクト60とを、平板30によって区画するようにしたが、この平板30に、複数の素電池100の電極間を電気的に接続する機能を付加することもできる。
図15~図19を参照しながら、本実施形態における電池モジュールの構成を適用した具体例を説明する。
第1の実施形態では、排気ダクト60を、隔壁40によって、第1の空間61と第2の空間62とに区画したが、第1の空間61から第2の空間62に排出されたガスは、第1の空間61によって、酸素と反応しない温度以下になっているため、第2の空間62内では、ガスが発火するおそれはない。従って、第2の空間62では、第1の空間61と異なり、できるだけ小さな容積で断熱膨張をさせる要請はなく、第1の空間と比べて、比較的大きな容積を許容する。換言すれば、第2の空間62に相当する排気空間は、複数の素電池100を収容するケース20内に必ずしも設ける必要はない。
