Process for Preparation of Anode Active Material

The present invention, the composite comprises a hydrophilic material comprising the crystalline and the core (core) of the carbon-based material, a low crystallinity carbon and one or more materials as ion occlusion and release is possible oxides selected from the group consisting of amorphous carbon coating a method for manufacturing a negative electrode active material consisting of a (composite coating layer), (a) a low crystallinity carbon and a possible oxide occlusion and release of ions in the precursor of the starting material for the production of one or more materials selected from the group consisting of amorphous carbon purification by mixing the hydrophilic substance comprising: preparing a coating mixture for that; Preparing a shell precursor - (b) the coating mixture for the crystalline carbon-based material mixed with the crystalline carbon-based material The core material mixture for the coating on the core comprising coating a; (C) the core-to firing the shell precursor low crystalline to carbonizing a raw material for the production of one or more materials selected from the group consisting of carbon and amorphous carbon with one or more materials selected from the group consisting of low-crystalline carbon and amorphous carbon It provides a method for preparing a cathode active material comprising the; step.
