Abstract: PURPOSE: A manufacturing method of an anode active material is provided to mass produce the anode active material which has high surface porosity, and uniform composition and particle size, and capable of adjusting a particle size and a shape of the anode material. CONSTITUTION: A manufacturing method of an anode active material for a lithium secondary battery comprises: a step of manufacturing a metal salt solution which includes a lithium source, a manganese source, a nickel source and cobalt source; a step of manufacturing a slurry by performing a wet grinding of the metal salt solution at 2000-6000 rpm for 2-12 hours with using a beads in which a particle diameter is 0.05-0.30 mm; a step of adding a carbon source in the slurry; a step of manufacturing s mixed powder by drying with spraying the slurry; a step of heat-treating the mixed powder.
