NEGATIVE ELECTRODE ACTIVE MATERIAL FOR RECHARGABLE LITHIUM BATTERY, METHOD FOR MANUFACTURING THE SAME, AND RECHARGABLE LITHIUM BATTERY INCLUDING THE SAME

摘要

The present invention relates to a negative electrode active material for lithium secondary batteries, a production method thereof, and a lithium secondary battery comprising the same. More specifically, provided is a negative electrode active material for lithium secondary batteries, which comprises: a graphite-based core particle including pores inside; a first coating layer positioned on a surface of the graphite-based core particle and containing metallic minute particles; and a second coating layer distributed on some portions or the entire surface of the first coating layer and containing conductive particles, wherein the coating layers are formed without a binder. Also provided are a method for producing the negative electrode active material for lithium secondary batteries, and a lithium secondary battery comprising the same.
