摘要： Disclosed is a method for manufacturing a separator. The method includes (S1) preparing a porous planar substrate having a plurality of pores, (S2) preparing a slurry containing inorganic particles dispersed therein and a polymer solution including a first binder polymer and a second binder polymer in a solvent, and coating the slurry on at least one surface of the porous substrate, (S3) spraying a non-solvent incapable of dissolving the second binder polymer on the slurry, and (S4) simultaneously removing the solvent and the non-solvent by drying. According to the method, a separator with good bindability to electrodes can be manufactured in an easy manner. In addition, problems associated with the separation of inorganic particles in the course of manufacturing an electrochemical device can be avoided.

摘要： A jelly-roll type electrode assembly is disclosed. The jelly-roll type electrode assembly includes an anode, a cathode, and separators interposed between the anode and the cathode and having a greater length than width. Each of the separators is longer than the anode and the cathode. Each of the separators has a porous substrate and porous coating layers formed on both surfaces of the porous substrate. The porous coating layers include a mixture of inorganic particles and a binder polymer. The porous coating layers are formed only in areas where the separators are in contact with the anode and the cathode. The porous coating layers enhance the heat resistance of the separators. Due to the enhanced heat resistance, the separators can prevent the performance of a battery from deteriorating. In addition, the porous coating layers can be prevented from being separated from the separators during battery assembly processing.
