Zusammenfassung:PURPOSE: An amorphous carbon anodal active material is provided to contain heterogeneity atom, thereby showing excellent initial efficiency, reversible capacity, and high-rate characteristic. CONSTITUTION: An amorphous carbon anodal active material comprises 0-1 wt% of more than one heterogeneity atom selected from a group comprising nitrogen, boron, silicone, and phosphorus. The amorphous carbon anodal active material comprises carbon component originated from at least one carbon precursor selected from a group comprising petroleum type pitch, coal type pitch, petroleum coke, carboniferous group coke, and their derivatives. A cathode for a lithium secondary battery comprises: an anodal active material comprising the amorphous carbon anodal active material; a conductive material, and an organic binder.
