摘要： An organic/inorganic composite separator includes (a) a polyolefin porous substrate having pores; and (b) a porous active layer containing a mixture of inorganic particles and a binder polymer, with which at least one surface of the polyolefin porous substrate is coated, wherein the porous active layer has a peeling force of 5 gf/cm or above, and a thermal shrinkage of the separator after being left alone at 150°C. for 1 hour is 50% or below in a machine direction (MD) or in a transverse direction (TD). This organic/inorganic composite separator solves the problem that inorganic particles in the porous active layer formed on the porous substrate are extracted during an assembly process of an electrochemical device, and also it may prevent an electric short circuit between cathode and anode even when the electrochemical device is overheated.

摘要： A separator includes a porous substrate having a plurality of pores; and a porous coating layer formed on at least one surface of the porous substrate and made of a mixture of a plurality of inorganic particles and a binder polymer, wherein the binder polymer includes a first polyvinylidene fluoride based copolymer having solubility of 25 weight % or more with respect to acetone at 35° C.; a second polyvinylidene fluoride-based copolymer having solubility of 10 weight % or less with respect to acetone at 35° C.; and a polymer having a cyano group. This separator decelerates deterioration of life span of an electrochemical device, and prevents disintercalation of inorganic particles in the porous coating layer, thereby improving safety of the electrochemical device.

摘要： An electrochemical device includes a plurality of unit cells, each having a first separator and a cathode and an anode positioned at both sides of the first separator, and a continuous single second separator interposed between adjacent unit cells in correspondence with each other in a laminated pattern and arranged to surround each unit cell. The first separator includes a heat- resisting porous substrate having a melt point of 200°C or above and a first porous coating layer formed on at least one surface of the heat-resisting porous substrate and made of a mixture of a plurality of inorganic particles and a binder polymer. The second separator includes a polyolefin porous substrate and a second porous coating layer formed on at least one surface of the polyolefin porous substrate and made of a mixture of a plurality of inorganic particles and a binder polymer.
