摘要： Disclosed is a method of manufacturing a porous separator including an elastic material, and a separator manufactured by the method. The separator includes an elastic material being uniformly dispersed in a polymer at a weight ratio of 40:60 to 5:95, and a value of elongation at break in a low tensile strength direction at room temperature is greater than or equal to 250%. In addition, the method of manufacturing a porous separator includes forming an extruded sheet by extruding a mixture of a polymer and an elastic material at a weight ratio of 95:5 to 60:40, forming a film by annealing and stretching the extruded sheet, and forming a porous separator by heat setting the stretched film. Accordingly, a thermal shrinkage ratio of the film is reduced and an elongation at break is greatly increased, to provide a porous separator with improved stability.
