摘要： The present disclosure relates to an invention directed to a composite separator having a porous coating layer, where the porous coating layer is prepared from a slurry by adjusting a particle diameter of an inorganic matter that is an ingredient of the slurry, so that a sinking rate of the inorganic particles may remarkably slow down and dispersibility may be dramatically improved, and as a result, the content of the inorganic particles may relatively increase and the inorganic particles may be uniformly distributed in the coating layer on a substrate, thereby preventing a reduction in battery performance.

摘要： A pouch type secondary battery includes an electrode assembly and a pouch sheath material including a first pouch portion and a second pouch portion. The pouch-type secondary battery includes dual electrode leads wherein a first electrode lead is attached to the first pouch portion and a second electrode lead is attached to the second pouch portion. In the pouch-type secondary battery, electric current is interrupted by using a volumetric swelling phenomenon caused by swelling or pressure generated upon overcharge so that the battery may be prevented from being further charged. In addition, when pressure is increased by an additional reaction, venting occurs toward the inner lead portion of each of the dual electrode leads. As a result, it is possible to increase the stability of a battery cell, module and a pack received in the pouch, and thus to improve the life of a battery.

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.
