Disclosed is an anode material comprising a metal core layer capable of repetitive lithium intercalation/deintercalation; an amorphous carbon layer coated on the surface of the metal core layer; and a crystalline carbon layer coated on the amorphous carbon layer. The anode material not only maintains a high charge/discharge capacity, which is an advantage of a metal-based anode material, but also inhibits changes in the volume of a metal core layer caused by repetitive lithium intercalation/deintercalation in virtue of an amorphous carbon layer and a crystalline carbon layer, thereby improving the cycle life characteristics of cells.

L'invention concerne un matériau anodique, qui comprend une couche centrale métallique permettant une intercalation/désintercalation répétitive du lithium; une couche de carbone amorphe disposée en revêtement à la surface de la couche centrale métallique; et une couche de carbone cristallin disposée en revêtement à la surface de la couche de carbone amorphe. Le matériau anodique non seulement maintient une haute capacité de charge/décharge, ce qui représente une caractéristique avantageuse d'un matériau anodique à base de métal, mais inhibe également des modifications du volume de la couche centrale métallique dues à une intercalation/désintercalation répétitive du lithium, grâce à la couche de carbone amorphe et à la couche de carbone cristallin, d'où une amélioration des caractéristiques de longévité des cellules.
