POLYOLEFIN MICROPOROUS MEMBRANE AND METHOD OF PRODUCING THE SAME, SEPARATOR FOR NON-AQUEOUS SECONDARY BATTERY AND NON-AQUEOUS SECONDARY BATTERY
Abstract:
The present invention provides a separator for a non-aqueous secondary battery, the separator including: a polyolefin microporous membrane having a degree of crystallinity of from 60 to 85% and a tie molecular volume fraction of from 0.7 to 1.7%; and a heat resistant porous layer containing a heat resistant resin and provided on one side or both sides of the polyolefin microporous membrane.
Abstract(Chinese):

本发明提供一种非水二次电池用隔膜，所述隔膜包括：结晶度为60〜85％，粘结分子体积分数为0.7〜1.7％的聚烯烃微多孔膜; 以及含有耐热性树脂的耐热多孔层，设置在聚烯烃微多孔膜的一侧或两侧。
