摘要： Disclosed is an organic/inorganic composite separator including: a porous substrate having pores; and a porous active layer containing a mixture of inorganic particles and a binder polymer with which at least one surface of the porous substrate is coated. The organic/inorganic composite separator of the present invention may be useful to enhance peeling and scratch resistances and improve a lamination characteristic by introducing a porous active layer onto a porous substrate having pores, the porous active layer having heterogeneity of morphology toward a thickness direction in which a content ratio of the binder polymer/inorganic particles present in a surface layer is higher than that of the binder polymer/inorganic particles present inside the surface layer. Accordingly, the stability and performances of a battery can be improved together since the detachment of inorganic particles from the porous active layer may be reduced during the assembly process of the electrochemical device.

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： 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 15O°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： The present invention provides an organic/inorganic composite porous separator, which comprises: (a) a porous substrate having pores; and (b) an organic/inorganic composite 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 porous particles and a binder polymer, wherein the inorganic porous particles have a plurality of macropores with a diameter of 50nm or greater in the particle itself thereby form a pore structure, a manufacturing method thereof, and an electrochemical device using the same. As an additional pathway for lithium ions is created due to a number of pores existing in the inorganic porous particle itself, degradation in the battery performance can be minimized, and energy density per unit weight can be increased by the weight loss effect.
