ANODE ACTIVE MATERIAL FOR SODIUM SECONDARY BATTERY AND METHOD FOR PRODUCING SAME

摘要

The present invention relates to an anode active material for a sodium secondary battery and a method for producing same and, more specifically, to an anode active material, having a new O3 structure, for a sodium secondary battery and a method for producing same. The anode active material for a sodium secondary battery according to the present invention has an O3 structure and thus is structurally stable, unlike conventional anode active materials, and accordingly, a sodium battery comprising the anode active material for a sodium secondary battery according to the present invention exhibits excellent lifespan characteristics.
