SULFUR FELT MOLDING SYSTEM FOR SODIUM SULFUR BATTERY CATHODE

摘要

PURPOSE: A sulfur felt molding system for the cathode of a sodium sulfur battery is provided to minimize a time for liquefying sulfur, to not consume a separate power to inject liquid sulfur, and to prevent the collection of bubbles in a felt in advance. CONSTITUTION: A sulfur felt molding system for the cathode of a sodium sulfur battery includes a vacuum chamber (100); a molding part (200) which is located in the vacuum chamber and molds a felt; a vacuum pump (300) which forms a vacuum in the vacuum chamber; and a sulfur tank (400) which is located in the upper part of the vacuum chamber, and liquefies powder sulfur to inject the liquid sulfur into the molding part.
