Abstract
Provided are a negative electrode active material including a three-dimensional composite. The three-dimensional composite includes secondary particles containing a silicon carbide-based (SiCx, 0<x≤1) nanosheet having a bent portion and amorphous carbon. Also provided are a method of producing the same, and a negative electrode and a lithium secondary battery including the negative electrode active material.
