Beschreibung
Zusammenfassung:	Provided is a separator having a first layer, the first layer being composed of organic additives and 95 wt% or more of a porous polyolefin. The convergence time of the temperature rise of the first layer when impregnated with N-methyl pyrrolidone containing 3 wt% of water and then irradiated with an 1800 W-output microwave having a frequency of 2455 MHz is 2.9-5.7 s*m2/g, and the white index of the first layer is 86-98. 本发明提供一种间隔件，其具有第一层，所述第一层包含有机添加剂和95重量％以上的多孔聚烯烃。使第一层浸渗于包含3重量％水的N-甲基吡咯烷酮后，以1800W的输出功率对第一层照射频率2455MHz的微波时的第一层的温度上升收敛时间为2.9s·m/g以上且5.7s·m/g以下，第一层的白色指数为86以上且98以下。
