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.

Abstract: The invention relates to a cable connector assembly for equipment connection, including a cable connector having a connector housing for receiving a cable and a restraining part formed along an outer periphery of the connector housing; and an equipment connection unit having a frame body assembled with the connector housing while surrounding the connector housing, an engaging part engaged with the restraining part of the cable connector, and a fastening means formed in the frame body and configured for connection with an equipment, wherein the equipment connection unit provides a flange function when the cable connector assembly is connected with the equipment. The cable connector assembly can provide connection between a cable and an equipment as well as between cables. Therefore, the present invention eliminates the need that a connector for a cable and a connector for equipment connection should be manufactured separately, thereby considerably reducing the connector manufacturing costs.

Abstract: The present invention relates to a method for a surface treatment of a layered structure oxide for a positive electrode in a lithium secondary battery. The method includes coating the surface of the layered structure oxide with a lithium transition metal oxide. The lithium secondary battery where the layered structure oxide is used as an active material of the positive electrode solves the problem of the thermal stability suffered conventionally.
