SELF-SUPPORTING CERAMIC SEPARATOR FOR ELECTROCHEMICAL DEVICE AND ELECTROCHEMICAL DEVICE COMPRISING SAME

A self-standing ceramic separator and an electrochemical device including the same are provided. The self-standing ceramic separator includes first inorganic particles having a sheet shape and second inorganic particles, which is a zeolite-based inorganic matter, in an appropriate content and arrangement, thereby having an improved heat resistance, and providing improved safety of a battery by preventing an electrical short-circuit between electrodes and a high cell lifespan characteristic.
