Description
本出願は、2016年3月3日出願の韓国特許出願第10−2016−0025759号に基づく優先権を主張し、該当出願の明細書及び図面に開示された内容は、すべて本出願に援用される。
前記緩衝パッドの両端面は、セルの外部フレームに接触することが望ましい。
前記緩衝パッドの平面部の面積は、前記セルの平面部の面積の105%未満であることが望ましい。
前記緩衝パッドの厚さは、前記セルの体積膨張率の120%〜250%であることが望ましい。
前記緩衝パッドの熱伝導率は、1.5〜1.6W/mKであることが望ましい。
前記緩衝パッドは、ポリジメチルシロキサン材質からなることが望ましい。
前記緩衝パッドは、UL94 V−1以上等級の不(難)燃性素材であって、且つ、10kV/mm以上の絶縁性素材からなり、ストレイン(strain)20〜60%の区間でCFD(Compression Force Deflection)が20〜100kPaであることが望ましい。
また、緩衝パッドとセルとの平面部分が互いに実質的に一致するように面接触することで、セルの体積膨張を効果的に吸収して、熱伝導率が最適化され、高効率の熱伝達機能を提供することができる。
図1及び図2を参照すれば、本発明の望ましい実施例によるセルアセンブリは、複数のセル100、及びセル100同士の間に介在されて1つの部品で緩衝機能と熱伝達機能を共に提供する緩衝パッド110を含む。
101 電極リード
110 緩衝パッド
120 外部フレーム
