METHOD FOR MANUFACTURING ANODE ACTIVE MATERIAL |
摘要 |
The present invention provides a method for manufacturing an anode active material, and comprises the steps of: (a) preparing a coating mixture from one or more raw materials selected from the group consisting of low crystallinity carbon and amorphous carbon, and then mixing with an ion absorption precursor and a releasable silicon oxide, followed by purification; (b) preparing a precursor coating for a core shell by combining the coating mixture with a crystalline carbon material for coating a core; and (c) carbonizing the one or more raw materials selected from the group consisting of low crystallinity carbon and amorphous carbon, then calcining into spheres the one or more raw materials selected from the group consisting of low crystallinity carbon and amorphous carbon. |
