| titleOfInvention | Methods of preparation for electrode active materials of lithium secondary batteries and lithium secondary batteries containing the electrode active materials |
| abstract | The present invention relates to a method for producing an active material precursor having improved tap density by preparing two or more kinds of active material precursors having a particle size distribution of a normal distribution curve in the production of a precursor and an active material of an electrode active material by using a batch reactor to provide. In the present invention, active material precursor powders are prepared by varying the reaction conditions in each reactor by using a multi-batch reactor including two or more reactors, and the final active material precursor is prepared by mixing the powders. Further, the powders are assembled, crushed or filtered A process of finely adjusting the particle size distribution may be included. In accordance with the present invention, in addition to the advantages of conventional batch reactors having high flexibility and high reproducibility, an active material precursor having an improved tap density can be produced and used in the production of electrodes, thereby providing a lithium secondary battery having high density energy characteristics. |
