Description

本考案はバッテリモジュールに関し、特にバッテリモジュール内部に導電放熱板を設置したバッテリモジュールを指す。 The present invention relates to a battery module, and particularly refers to a battery module in which a conductive heat sink is installed inside the battery module.

近年、各種ポータブル電子機器／電気自動車／エネルギー貯蔵ステーションなどの分野の急速な発展に伴い、エネルギー貯蔵密度が比較的高く、環境保護を兼ね備えたエネルギー貯蔵装置に対する高度な要求が大きくなっている。イオン二次電池は第１候補となっており、さらにはリチウムイオン二次電池、マグネシウムイオン二次電池、ナトリウムイオン二次電池などの各種二次電池に発展している。実務において、最もよく見られるのは、バッテリセルから並列接続の方式を採用してバッテリモジュールを構成したものであり、十分な容量を達成して各種装置に利用される。 In recent years, with the rapid development of various portable electronic devices/electric vehicles/energy storage stations and other fields, there has been a growing demand for energy storage devices with relatively high energy storage density and environmental protection. Ion secondary batteries are the first candidate, and have been further developed into various secondary batteries such as lithium ion secondary batteries, magnesium ion secondary batteries, and sodium ion secondary batteries. In practice, what is most commonly seen is a battery module constructed by connecting battery cells in parallel, which achieves sufficient capacity and is used in various devices.

既存のバッテリモジュールは、相互に接続してバッテリモジュールを形成する（例えば直列接続）場合、追加でタブリードにより電気的に接続する必要がある。このような接続方式は工程を複雑にするだけでなく、バッテリモジュール全体の体積利用率も低下させる。もう１つの既存の方式は、バッテリモジュールの相互間を集電層により面及び面を直接接触させ、必要な電気的接続を構成する。しかしながら、集電層により面及び面を直接接触させて電気的接続を構成するため、生じた熱エネルギーを排出するのが難しく、バッテリモジュールの性能に深刻な影響を及ぼす。 Existing battery modules require additional electrical connection via tab leads when interconnected to form a battery module (eg, series connection). Such a connection method not only complicates the process, but also reduces the volume utilization rate of the entire battery module. Another existing approach is to bring the battery modules into direct face-to-face contact with each other through current collecting layers to make the necessary electrical connections. However, since the electrical connection is formed by direct surface-to-surface contact using the current collecting layer, it is difficult to dissipate the generated thermal energy, which seriously affects the performance of the battery module.

さらに、一般的なバッテリモジュールの放熱方式は、バッテリモジュールに冷却システム又は冷却板を加えることを採用している。このようにすると、バッテリモジュールの全体の体積が増加し、バッテリモジュールを均等に冷却するのが難しく、同様に、バッテリを組み立てる工程もより繁雑になる。 Furthermore, a common heat dissipation method for battery modules employs adding a cooling system or a cooling plate to the battery module. This increases the overall volume of the battery module, makes it difficult to cool the battery module evenly, and also makes the process of assembling the battery more complicated.

上記既存技術の欠点に基づいて、本考案は導電放熱板を備えたバッテリモジュールを示し、上記課題を効果的に解決する。 Based on the above drawbacks of the existing technology, the present invention presents a battery module with a conductive heat sink to effectively solve the above problems.

本考案の主な目的は、導電放熱板を備えたバッテリモジュールを提供することにある。導電放熱板を隣接する任意の２つのバッテリセルの間に直接挟み、電気的な接続及び放熱の目的を直接達成する。従来採用される外部接続のタブリード又はタブ及び追加の冷却システムを省き、高い体積利用率及び高効率の放熱を兼ね備えた効果を達成する。 The main purpose of the present invention is to provide a battery module with a conductive heat sink. A conductive heat dissipation plate is directly sandwiched between any two adjacent battery cells to directly achieve the purpose of electrical connection and heat dissipation. It eliminates the conventionally employed external connection tab lead or tab and additional cooling system, achieving a combination of high volume utilization and high efficiency heat dissipation.

本考案のもう１つの目的は、導電放熱板を備えたバッテリモジュールを提供することにある。板状電気絶縁本体にマイクロチャネルをはめ込み、放熱効果を大幅に高め、バッテリモジュール全体の性能を高めることが可能である。 Another object of the present invention is to provide a battery module with a conductive heat sink. By incorporating microchannels into the plate-shaped electrically insulating body, it is possible to greatly enhance the heat dissipation effect and improve the overall performance of the battery module.

A battery module is formed by stacking a plurality of battery cells in a single axial direction, and each battery cell is placed parallel to each other and has two plate-like current collecting layers, which are the power output ends of different electrodes of the battery cells. include. The conductive heat sink has a plate-shaped electrically insulating body and at least one conductive part installed in the plate-shaped electrically insulating body, and is sandwiched between any two adjacent battery cells.

Ion conduction and movement can be achieved at the same time, and the generated electrons can be directly guided outside from the plate-like current collecting layers 24 and 25. The materials of the plate-shaped current collecting layers 24 and 25 are generally copper and aluminum, but other metals or metal alloys such as nickel, tin, silver, and gold may also be used.

さらに、板状集電層２４、２５を周縁のシーラント２６と組み合わせて、バッテリセル２０の封止モジュールとする。シーラント２６は重合体材料であり、板状集電層２４、２５の表面に接着固定でき、さらに電解質システムに対して耐久性があればよく、特に制限されない。例を挙げると、シーラント２６の材質はエポキシ樹脂、ポリエチレン、ポリプロピレン、ポリウレタン、熱可塑性ポリイミド、シリコーン樹脂、アクリル樹脂、シリコーンゴム又は紫外線硬化接着剤でよく、２つの板状集電層２４、２５の周縁に設けられ、電気化学システム２０１（活物質層２２、２３及び中間のセパレータ２１）を取り囲んで封止する。さらに２つの板状集電層２４、２５を接着するのに用いられ、電解質システムを２つの板状集電層２４、２５の間に封止して漏出させず、かつ他のバッテリセル２０の電解質システムと相互に流動しないようにする。従って、バッテリセル２０は板状集電層２４、２５及びシーラント２６を直接採用し、封止構造として形成された独立して完全な電力供給を行うモジュールである。 Further, the plate-shaped current collecting layers 24 and 25 are combined with a peripheral sealant 26 to form a sealed module of the battery cell 20. The sealant 26 is a polymer material, and is not particularly limited as long as it can be adhesively fixed to the surfaces of the plate-shaped current collecting layers 24 and 25 and has durability against the electrolyte system. For example, the material of the sealant 26 may be epoxy resin, polyethylene, polypropylene, polyurethane, thermoplastic polyimide, silicone resin, acrylic resin, silicone rubber, or ultraviolet curing adhesive, It is provided at the periphery and surrounds and seals the electrochemical system 201 (active material layers 22, 23 and intermediate separator 21). Furthermore, it is used to bond the two plate-shaped current collecting layers 24 , 25 , to seal the electrolyte system between the two plate-shaped current collecting layers 24 , 25 to prevent leakage, and to prevent leakage of the electrolyte system between the two plate-shaped current collecting layers 24 , 25 . Avoid interflow with electrolyte system. Therefore, the battery cell 20 is a module that directly employs the plate-like current collecting layers 24, 25 and the sealant 26, and is formed as a sealed structure and provides an independent and complete power supply.

シーラント２６の封止効果をより好ましくするため、シリコーンゴム材質を採用するとき、シーラント２６が３層の構造を有するように設計できる。図２Ｂを参照されたい。上下２層は変性シリコーンゴム層２６１、２６２、中間はシリコーンゴム層２６３であり、両側の変性シリコーンゴム層２６１、２６２は、付加型シリコーンゴム及び縮合型シリコーンゴムの組成比率を調整することにより、又は添加物を添加することによりシリコーンゴムを変性させ、異なる性質の材料（つまり板状集電層２４、２５及び中間のシリコーンゴム層２６３）への接着に適するようにする。この設計により境界面間の接着力を高めることが可能であり、同時に、これにより外観全体の完全性がより高く、生産良品率も高くなる。 In order to improve the sealing effect of the sealant 26, when silicone rubber is used, the sealant 26 can be designed to have a three-layer structure. See Figure 2B. The upper and lower two layers are modified silicone rubber layers 261 and 262, and the middle is a silicone rubber layer 263.The modified silicone rubber layers 261 and 262 on both sides are made by adjusting the composition ratio of addition type silicone rubber and condensation type silicone rubber. Alternatively, the silicone rubber can be modified by adding additives to make it suitable for adhesion to materials of different nature (ie, the plate-like current collecting layers 24, 25 and the intermediate silicone rubber layer 263). This design allows for increased adhesion between interfaces, which at the same time provides higher overall appearance integrity and higher production yield.
