    摘要： The present invention relates to a negative electrode active material for a lithium secondary battery, a preparation method thereof, and a lithium secondary battery containing the negative electrode active material. The negative electrode active material for the lithium secondary battery according to the present invention is formed by mixing: a carbon material coated with vapor growth carbon fiber (VGCF) and amorphous graphite; and one or more kinds of other carbon material selected from natural graphite, artificial graphite, amorphous-coated graphite, resin-coated graphite and amorphous carbon. According to the present invention, when the negative electrode active material is prepared, the carbon fiber is uniformly dispersed-throughout the carbon material, and the carbon material is coated with the amorphous graphite and then mixed with other carbon materials, and thus, a high electrode density can be achieved. Accordingly, even with high electrode density, the invention can provide the negative electrode active material with excellent electrochemical properties such as charge/discharge efficiency and cycle characteristics.
