Description
(1)ビガット軟化点115℃以上、融点150℃以上のホモタイプ、
(2)ビガット軟化点105℃以上、融点130℃以上のエチレンープロピレンとの共重合体(ランダム共重合タイプ)
(3)融点110℃以上である不飽和カルボン酸を用い酸変性重合した単体又はブレンド物等を用いることができる。
[包装材料の試料作製]
上記方法により作製した本発明1〜本発明3及び比較例1にかかる電気化学セル用包装材料を40mm×120mmの短冊片に裁断し、表面に平均粒径44μmのカーボン粒子をまぶしたニッケルタブ(4mm×30mm)とポリプロピレン側の面とを当接させ、ヒーシールバー(幅30mm)を0.5MPa、190℃で押圧してニッケルタブと各試料をヒートシールした。このとき、カーボン粒子がヒートシールバーの押圧によりポリプロピレン及び酸変性ポリプロピレンへ噛み込み、ニッケルタブと包装材料間の絶縁性が低下する時間を測定し、その結果を表1に示す。なお、ニッケルタブと包装材料間の絶縁性が低下する時間とはニッケルタブとアルミニウム間に25Vの電圧を印加し、抵抗値が100MΩ以下になる時間のことをいう。
実施例1において作製した本発明1〜本発明3及び比較例1にかかる電気化学セル用包装材料を裁断して15mm×250mmの短冊片を作製し、引張り試験機(島津製作所製、AGS−50D(商品名))によりアルミニウム箔と酸変性ポリプロピレン間を300mm/分の速度で剥離させながら、剥離時の強度を測定し、その強度をラミネート強度として表2に示す。なお、単位はN/15mm巾である。
実施例1において作製した本発明1〜本発明3及び比較例1にかかる電気化学セル用包装材料を裁断して15mm×250mmの短冊片を作製し、その短冊片を85℃の電解液に24時間ドブ漬けした。その後、引張り試験機(島津製作所製、AGS−50D(商品名))によりアルミニウム箔と酸変性ポリプロピレン間を300mm/分の速度で剥離させながら、剥離時の強度を測定し、その強度を電解液浸漬後のラミネート強度として表2に示す。なお、単位はN/15mm巾である。
