Abstract
【解決手段】正極板と負極板との間に配置され、正極板及び負極板とともに複数層積層される第一セパレータ430であって、第一層431と、第一層431上に配置される、第一層431と材質が異なる第二層432とを備え、第一層431と第二層432との端部の剥離強度は、中央部の剥離強度よりも高い。
【選択図】図3B
Description
次に、本実施の形態の変形例1について説明する。上記実施の形態では、第一層431または第二層432は、端部の方が中央部よりも熱可塑性樹脂の含有量が多いこととした。しかし、本変形例1では、第一層431または第二層432は、端部の方が中央部よりも熱溶着性が高い熱可塑性樹脂を含んでいる。
次に、本実施の形態の変形例2について説明する。上記実施の形態では、第一層431と第二層432との両端部の剥離強度が、中央部の剥離強度よりも高いこととした。しかし、本変形例2では、第一層431と第二層432とのいずれか一方の端部の剥離強度のみが中央部の剥離強度よりも高い。
次に、本実施の形態の変形例3について説明する。上記実施の形態では、第一層431と第二層432との端部とは、図3Aに示す第一セパレータ430の長手方向(同図のX軸方向)の端部であるセパレータ端部430a、430bであることとした。しかし、本変形例3では、第一セパレータの短手方向の端部を、第一層と第二層との端部であることにする。
