Reactor methods for preparing precursors of cathode active materials for lithium ion secondary batteries by using the same precursors prepared by the same cathode active materials

摘要

The present invention is characterized in that the metal raw material is supplied by an eductor in order to propose a method for solving the swirling and vertex phenomenon inside the co-precipitation reactor for producing a precursor of a lithium secondary battery and enabling strong stirring and diffusion of the raw material A reactor for preparing a precursor for a lithium secondary battery is provided, and a method for preparing a precursor for preparing a cathode active material for a lithium secondary battery using a co-precipitation method in the reactor is provided. In addition, it provides a precursor prepared therefrom, a positive electrode active material and a lithium secondary battery comprising the same.
