Beschreibung
Zusammenfassung:	A negative active material, a negative electrode, a lithium battery including the negative active material, and a method of manufacturing the negative active material, the negative electrode, and the lithium battery. The negative active material includes a silicon-based alloy including Si, Ti, Ni, and Fe components. The silicon-based alloy includes a Ti2Ni phase as an inactive phase and active silicon having a lower content than that of typical silicon-based alloys. The negative active material may improve discharge capacity and lifetime characteristics of lithium batteries.
