摘要：A jelly-roll type electrode assembly is disclosed. The jelly-roll type electrodeassembly includes an anode, a cathode, and separators interposed between the anodeand 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 andporous coating layers formed on both surfaces of the porous substrate. The porouscoating layers include a mixture of inorganic particles and a binder polymer. The porouscoating layers are formed only in areas where the separators are in contact with theanode and the cathode. The porous coating layers enhance the heat resistance of theseparators. Due to the enhanced heat resistance, the separators can prevent theperformance of a battery from deteriorating. In addition, the porous coating layers canbe prevented from being separated from the separators during battery assemblyprocessing.
