ARTIFICIAL GRAPHITE, METHOD FOR PREPARING ARTIFICIAL GRAPHITE, ANODE COMPRISING SAME, AND LITHIUM SECONDARY BATTERY

A method for preparing artificial graphite, including the steps of: pulverizing a carbonaceous material; carrying out a first deferrization to remove magnetic foreign materials generated by pulverizing the carbonaceous material to form a first deferrization product; granulating the first deferrization product of the first deferrization step to form a granulated product; graphitizing the granulated product to form a graphitized product; and carrying out a second deferrization on the graphitized product to remove magnetic foreign materials from the graphitized product to form the artificial graphite. A negative electrode including the artificial graphite and a lithium secondary battery including the negative electrode are also disclosed.
