Abstract
A negative active material, a lithium battery including the negative active material, and a method of preparing the negative active material. The negative active material includes: a core particle including a silicon based alloy; carbon nanoparticles disposed on a surface of the core particle; and an amorphous carbonaceous coating layer disposed on at least a portion of a surface of the core particle. The negative active material may improve the lifetime characteristics of the lithium batteries.
