PROBLEM TO BE SOLVED: To provide a negative electrode active material, a negative electrode including the negative electrode active material, a lithium battery, and a method of manufacturing the negative electrode active material.SOLUTION: The present invention relates to a negative electrode active material, a negative electrode including the negative electrode active material, a lithium battery, and a method of manufacturing the negative electrode active material. The negative electrode active material includes a silicon-based alloy consisting of Si, Ti, Ni, Fe and inevitable impurities. The silicon-based alloy includes a TiNi phase as an inactive phase and active silicon having a lower content than that of conventional ones. The negative electrode active material may improve discharge capacity and lifetime characteristics of lithium batteries. |
