摘要
The present invention relates to a negative electrode material of a lithium secondary battery, a manufacturing method of the negative electrode material, and a lithium secondary battery comprising a negative electrode made of the negative electrode material. The negative electrode material of the lithium secondary battery according to the present invention is prepared by uniformly inserting a small amount of tin oxide (SnO 2 ) as a second phase additive into a carbon powder used as a negative electrode material of a conventional lithium secondary battery using a charge titration method. . As such, the lithium secondary battery of the present invention including a negative electrode made of carbon powder surface-modified by tin oxide insertion exhibits a higher initial discharge capacity and a charging capacity than a lithium secondary battery including a negative electrode made of conventional carbon powder. In addition, it exhibits high reversibility and better cycleability.;Lithium secondary battery, negative electrode material, carbon electrode, tin oxide
