Beschreibung
Zusammenfassung:	The present invention relates to a method for producing a polyolefin-based porous separator and, more particularly, to a method for producing a separator having improved tensile strength and thermal shrinkage rate by adjusting the stretching factor of a base film during the casting and stretching processes of a separator production process. Also, the present invention relates to a polyolefin-based porous separator having a small difference in tensile strength between the longitudinal direction and the transverse direction of the separator, excellent tensile strength, and improved thermal shrinkage rate and improved puncture strength. Further, the present invention relates to an electrochemical battery, of which the dimensional stability under heat and tension is improved using the separator.
