Beschreibung
Zusammenfassung:	Disclosed herein relates to an evaluation method of a negative electrode active material for a lithium secondary battery and a negative electrode for a lithium secondary battery including a negative electrode active material determined to be suitable according to the method, wherein the evaluation method can determine the material suitability of a negative electrode active material contained in a secondary battery with high reliability by quantifying the degree of side reaction of the negative electrode active layer that may occur after activation in a non-destructive manner, and the negative electrode active material so determined has the advantage of having excellent high temperature stability and excellent life characteristics when applied to a negative electrode.
