CATHODE ACTIVE MATERIAL METHOD WITH IMPROVED ELECTROCHEMICAL PROPERTIES BY PULVERIZING AND MIXING CONDITIONS

摘要

The present invention relates to a method for manufacturing an anode active material in which electrochemical characteristics of a secondary battery are enhanced by pulverizing and mixing conditions. More specifically, the present invention relates to a method for manufacturing an anode active material having enhanced electrochemical characteristics in which an average particle size of a mixture of a lithium salt and a manganese salt doped with a nickel salt is reduced to increase a surface area of the anode active material by setting a rotation speed of a bead mill at 2000-3000 rpm during wet pulverization and mixing.
