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 comprises mixing a lithium compound, a water insoluble vanadium compound, optionally an M-containing compound, and a chelating agent in a solvent to produce a mixed solution, applying ultrasonic waves to the mixed solution to form droplets, and Spray-treating the droplets to prepare a negative active material of Chemical 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 the above formula, 0.01≤x≤0.5, 0≤y≤0.3, -0.2≤z≤0.2, M is in the group consisting of transition metals other than vanadium, alkali metals, alkaline earth metals, semimetals, and combinations thereof Element to be selected)n n n n Vanadium oxide, negative electrode active material, lithium secondary battery, average particle diameter, ultrasonic |
