ACTIVE MATERIAL COMPOSITE, ANODE AND LITHIUM BATTERY USING THE SAME

摘要

A composite anode active material is provided to ensure excellent initial efficiency and cycleability and to improve electrical characteristic of a lithium battery and an anode. A composite anode active material comprises tin(Sn), titanium(Ti), cobalt(Co) and carbon(C) as a component. The tin, titanium, cobalt and carbon are included in the amount of 100.0 parts by weight, 0.1-100.0 parts by weight, 10-150 parts by weight and 5-50 parts by weight. The type of each component is Sn2Co, SnCo, Ti, TiC, and carbon. The anode active material further includes silicon(Si) as a component.
