摘要： An organic/inorganic composite 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 with a plurality of inorganic particles and a binder polymer. The binder polymer is a copolymer including: (a) a first monomer unit having a contact angle to a water drop in the range from 0° to 49°; and (b) a second monomer unit having a contact angle to a water drop in the range from 50° to 130°. This organic/inorganic composite separator has excellent thermal stability, so it may restrain an electric short circuit between a cathode and an anode. In addition, the separator may prevent inorganic particles in the porous coating layer from being extracted during an assembling process of an electrochemical device, thereby improving stability of an electrochemical device.

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： Disclosed is an electrode having a current collector coated with an electrode active material, wherein non-coated regions of the electrode and boundary regions of intermittently pattern-coated electrodes are coated with a porous active layer including a mixture of inorganic particles and a binder polymer. The electrode of the present invention may be useful to improve safety of a battery and also minimize reduction in the capacity of a battery by introducing the porous active layer onto non-coated regions of the electrode and/or boundary regions of the intermittently pattern-coated electrodes to prevent internal short circuit caused by the contact between both electrodes, wherein the boundary regions are coated with the electrode active material but vulnerable to the electrical short circuit.

摘要： Disclosed is an organic/inorganic composite porous separator comprising: (a) a polyolefin-based separator substrate; and (b) an active layer formed by coating at least one region selected from the group consisting of a surface of the substrate and a part of pores present in the substrate with a mixture of inorganic particles and a binder polymer, wherein the inorganic particles in the active layer are interconnected among themselves and are fixed by the binder polymer, and interstitial volumes among the inorganic particles form a pore structure. A method for manufacturing the same separator and an electrochemical device including the same separator are also disclosed. An electrochemical device comprising the organic/inorganic composite porous separator shows improved thermal and electrochemical safety and quality, simultaneously.
