The present invention relates to a negative electrode active material for a lithium secondary battery including a tin-fullerene composite (Sn-PC 60 ; SPC), a negative electrode for a lithium secondary battery including the same, a lithium secondary battery, and a method of manufacturing the same. In the tin-fullerene composite (Sn-PC 60 ; SPC) of the present invention, nano-sized tin particles are uniformly distributed to prevent electrode degradation according to cycles (self-releasing effect on electrode volume expansion), and tin-tin oxide- By forming a layered structure of plasma polymerization fullerene, the rate characteristics are improved (the effect of accelerating the diffusion rate of lithium ions). |
