Description
また、本発明による非水電解質蓄電デバイスは、その正極側をアルミニウム、負極側を銅からなるリード導体として、上記の非水電解質蓄電デバイス用リード部材を用い、金属箔層を含む多層フィルムからなる封入袋体で封止する。その他、非水電解質蓄電デバイスの正極側および負極側の双方をアルミニウムからなるリード導体とし、上記の非水電解質蓄電デバイス用リード部材を用い、金属箔層を含む多層フィルムからなる封入袋体で封止するようにしてもよい。
リード部材3,4は、厚さが0.05mm〜0.50mm程度の薄い導体箔を長方形状にカットしてリード導体3’,4’とし、このリード導体の封入袋体からの取り出し部分に絶縁フィルム5を貼り付けて構成される。絶縁フィルム5は、リード導体の両面に位置を合わせて貼り合わされる。この絶縁フィルム5は、リード導体3’,4’の長さより短く、リード導体の幅より広いものが用いられる。
また、リード導体が硬質化されることで、導体表面に付着した切断紛や異物を、エアブロー処理(空気に吹き付け)で容易に除去することが可能となり、また、不用意な折り曲げが低減されるので、作業性を高めて不良品の発生を少なくでき、製造コストを抑制することが可能となる。
アルミニウムH材(抗張力 100MPa) 7.5km
アルミニウムO材(抗張力 75MPa) 5km
銅H材(抗張力 215MPa) 6km
銅O材(抗張力 195MPa) 3.5km
リード導体を打ち抜いて切断する場合は、H材を使用する方がO材を使用する場合に比べて、刃が交換必要となるほど劣化するまでの間に、多くの導体を切断することができる(ショット数を増やすことができる)。
図3(B)に示すように、繰り出しロール15から繰り出されたアルミニウム箔または銅箔の金属箔11を巻き取りロール16で巻き取り、両ロールの間で吹出しノズル17から空気を吹き付けて切断粉や異物を除去した。
Claims (3)
- 厚さが0.05〜0.50mm、伸びが2%以上15%以下および抗張力が100MPa以上の加工硬化されたアルミニウム、または、厚さが0.05〜0.50mm、伸びが2%以上15%以下および抗張力が215MPa以上の加工硬化された銅からなる箔状のリード導体に、絶縁フィルムが両面から貼り合わされていることを特徴とする非水電解質蓄電デバイス用リード部材。
- 正極側をアルミニウム、負極側を銅からなるリード導体とし、請求項1に記載の非水電解質蓄電デバイス用リード部材を用い、金属箔層を含む多層フィルムからなる封入袋体で封止したことを特徴とする非水電解質蓄電デバイス。
- 正極側および負極側の双方をアルミニウムからなるリード導体とし、請求項1に記載の非水電解質蓄電デバイス用リード部材を用い、金属箔層を含む多層フィルムからなる封入袋体で封止したことを特徴とする非水電解質蓄電デバイス。
