Anode active material precursor for lithium secondary battery, anode active material including same, and method for manufacturing same

An anode active material comprising:

• a carbon-based material including a metal compound and a petroleum-based pitch,
• wherein 3 to 10 parts by weight of petroleum-based pitch based on 100 parts by weight of the carbon-based material is included,
• a softening point of the petroleum-based pitch is 220 to 280° C., and
• a content of the metal compound is 10 ppm or more.

A method for manufacturing an anode active material precursor, the method comprising:

• preparing a carbon-based material including 10 ppm or more of a metal compound;
• adjusting a particle size of the carbon-based material to 13 to 18 μm;
• introducing 3 to 10 parts by weight of a petroleum-based binder pitch to the carbon-based material, based on 100 parts by weight of the carbon-based material;
• and
• mixing the carbon-based material and the petroleum-based binder pitch,
• wherein a softening point of the petroleum-based binder pitch is 220 to 280° C.
