  • Patent number: 8182939
    Abstract: 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.

  • Publication number: 20120100426
    Abstract: Provided is a lithium secondary battery which has excellent low-temperature power output characteristics by the inclusion of a given amount of a lithium metal oxide and/or a lithium metal sulfide in an anode mix for a lithium secondary battery containing a carbon-based anode active material and is thereby capable of being used as a power source for electric vehicles (EVs) and hybrid electric vehicles (HEVs) that must provide high-power output at low temperatures as well as at room temperature.
