NEGATIVE ACTIVE MATERIAL FOR RECHARGEABLE LITHIUM BATTERY, METHOD OF PREPARING THE SAME AND RECHARGEABLE LITHIUM BATTERY INCLUDING THE SAME

摘要

A negative active material for a rechargeable lithium battery includes a SiOx (0.5@x@1.5) compound including crystalline Si, and a SiCy, (0.5@y@1.5) compound including crystalline carbon. The negative active material may be used in a rechargeable lithium battery to achieve high capacity and good cycle-life characteristics.
