Abstract
A negative active material, an electrode including the same, and a lithium battery including the electrode. The negative active material has no volumetric expansion and has high solubility with respect to lithium. In addition, the negative active material is in the form of spherical particles, and thus does not require a separate granulating process. Moreover, the negative active material may enhance the capacity of a lithium battery.
