PRECURSOR OF NEGATIVE ELECTRODE ACTIVE MATERIAL FOR RECHARGEABLE LITHIUM BATTERY METHOD FOR MANUFACTURING NEGATIVE ELECTRODE ACTIVE MATERIAL FOR RECHARGEABLE LITHIUM BATTERY AND RECHARGEABLE LITHIUM BATTERY INCLUDING NEGATIVE ELECTRODE PREPARED FROM THE SAME

摘要

The present embodiments relate to a method of manufacturing a negative active material for a lithium secondary battery and a lithium secondary battery including a negative electrode manufactured using the same. According to an embodiment, preparing primary particles comprising a carbon raw material composed of coal-based green needle-like coke, adding a coal-based pitch having an average particle diameter (D50) in the range of 3 to 10 μm to the primary particles, and kneading It is possible to provide a method of manufacturing a negative active material comprising the steps of preparing secondary particles by granulation, carbonizing the secondary particles, and graphitizing the carbonized secondary particles.
