摘要:
Presented is a method for producing a negative electrode active material which has a high discharge capacity, high charge-discharge efficiency, and excellent high-output characteristics, and which experiences only a small volume change during charging/discharging. A method for producing a negative electrode active material for a lithium secondary battery according to an embodiment of the present invention includes: a step for producing primary particles by pulverizing a carbon raw material containing 4 to 10 wt% of volatile matters; a step for producing secondary particles by mixing the primary particles with a binder; and a step for producing a graphite material by graphitizing the secondary particles.
