Anode material for lithium secondary cell with high capacity |
摘要 |
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.
