Abstract
A negative active material, a negative electrode, a lithium battery including the negative active material, and a method of preparing the negative active material. The negative active material includes a crystalline carbonaceous substrate; and metal oxide nanoparticles disposed on a surface of the crystalline carbonaceous substrate, wherein the metal oxide nanoparticles have a rutile structure. The negative active material may be used to improve high temperature stability and lifespan characteristics of a lithium battery.
