Abstract
Description
図1は、実施形態に係る電磁波遮蔽構造を有する電池スタックの構成を示す斜視図である。図2は、電磁波遮蔽構造を取り除いた状態の電磁スタックを示す斜視図である。
図3は、電池スタック10を電池セル12の積層方向から見た正面図である。図3に示すように、遮蔽体30は、細長の直方体状の電池スタック10の上面および側面上部を覆い下方が開放したU字状断面を有する樹脂基板32と、その上面に配置された導電布34とから構成される。
本実施形態においては、導電布34を用いた。導電布34としては、導電性の繊維による織布など各種のものを採用できるが、例えば特許文献1に示したようなものの他、金属コーティングを施したポリエステル繊維の織布や、ポリエステル系短繊維から形成される不織布に金属めっき処理を施したものなどを採用することができる。
