Abstract
A negative active material for a rechargeable lithium battery includes a core including crystalline carbon, a metal nano particle and a MOx nano particle (where x is from 0.5 to 1.5, and M is Si, Sn, In, Al, or a combination thereof) disposed on the core surface, and a coating layer including an amorphous carbon surrounding the core surface, the metal nano particle and the MOx nano particle. A lithium rechargeable battery includes the negative active material.
