Elektrolytische Lösung tragender Polymerfilm und Sekundärbatterie

摘要

A high-strength, heat-resistant and high-safety electrolytic-solution-supporting polymer film which can be applied to secondary batteries typified by lithium and lithium ion secondary batteries and which has an ionic conductivity of at least 5 x 10<-4> S/cm at 25 DEG C, a puncture strength of at least 300 g and a mechanical heat resistance of at least 300 DEG C.
