The present invention relates to a method for producing a negative electrode active material for a lithium secondary battery and a lithium secondary battery including a negative electrode active material prepared according to the method. The method includes preparing a mixture by mixing a lithium raw material, a vanadium raw material, and optionally an M-containing compound, and reducing and calcining the mixture in a sealed reactor to prepare a negative electrode active material of Formula 1 below. .n n n [Formula 1]n n n Li 1 + x V 1 -X- y M y O 2 + z n n n In Formula 1, 0.01 ≦ x ≦ 0.5, 0 ≦ y ≦ 0.3, −0.2 ≦ z ≦ 0.2, and M is composed of transition metals other than vanadium, alkali metals, alkaline earth metals, semimetals, and combinations thereof Element selected from the group.)n n n n Lithium vanadium oxide, negative electrode active material, silicon tube, sealing, vacuum, lithium volatilization |
