Provided are a core-shell type anode active material for lithium secondary batteries including a carbonaceous material core; and a shell formed outside the carbonaceous material core, the shell including a PTC (Positive Temperature Coefficient) medium. The core-shell type anode active material for lithium secondary batteries has the shell including the PTC medium, and thus has the improved conductivity and high output density, exhibiting excellent electrical characteristics. And, a lithium secondary battery manufactured using the anode active material has excellent safety, in particular safety against overcharge and external short circuit.

L'invention porte sur un matériau actif d'anode du type à coeur et enveloppe pour batteries secondaires au lithium comprenant un coeur en matériau carboné; et une enveloppe formée à l'extérieur du coeur en matériau carboné, l'enveloppe comprenant un milieu à coefficient positif de température (PTC). Le matériau actif d'anode de type à coeur et enveloppe pour batteries secondaires au lithium comprend l'enveloppe comprenant le milieu PTC, et possède donc une conductivité améliorée et une densité de puissance élevée, présentant d'excellentes caractéristiques électriques. L'invention porte également sur une batterie secondaire au lithium fabriquée à l'aide du matériau actif d'anode qui présente une excellente sécurité, en particulier une sécurité contre la surcharge et les courts-circuits externes.
