Abstract: The present invention relates to a method of manufacturing a polyolefin-based porous separator. The present invention relates to a method of manufacturing a separator with improved tensile strength and thermal contraction rate by controlling a casting and a stretching process in a separator manufacturing process. Also, the present invention relates to a polyolefin-based porous separator which has excellent tensile strength and good thermal contraction rate and stingingness strength because the difference of the tensile strength in the horizontal and the vertical direction of the separator is small. Also, the present invention relates to an electrochemical battery which improves shape stability due to heat and tension by using the separator.

Abstract translation: 本发明涉及一种制造聚烯烃基多孔隔板的方法。 本发明涉及通过在分离器制造方法中控制铸造和拉伸工序来制造具有提高的拉伸强度和热收缩率的隔板的方法。 此外，本发明涉及一种聚烯烃类多孔隔膜，其隔膜的水平方向和垂直方向的拉伸强度的差异小，因此拉伸强度优异，热收缩率好，冲击强度高。 此外，本发明涉及一种电化学电池，其通过使用隔膜改善由热和张力引起的形状稳定性。
