The separator for nonaqueous electrolyte rechargeable batteries containing a layered product and a layered product, and a nonaqueous electrolyte rechargeable battery
Document Type and Number:
Japanese Patent JP5973674
Kind Code:
B1
Abstract:
非水電解液二次電池の各種性能を維持した上で、非水電解液二次電池の破損等による内部短絡を防止することによって高い安全性を確保することができる積層体を提供する。ポリオレフィンを主成分とする多孔質フィルムの少なくとも一方の面に、微粒子を含む多孔質層を積層させた積層体（１０）は、ＪＩＳ Ａ ５５０８で規定されるＮ５０の釘（２）を用い、釘（２）の降下速度５０μｍ／分の条件で測定した釘刺し導通試験における、積層体（１０）の導通時の試験力と絶縁破壊時の試験力との差（導通時の試験力−絶縁破壊時の試験力）が、５Ｎ以上、５０Ｎ以下である。
