CATHODE ACTIVE MATERIALS FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY COMPRISING THE SAME, AND PREPARATION METHOD FOR THE CATHODE ACTIVE MATERIAL

摘要

The present invention relates to an anode active material for lithium secondary battery which has excellent high-rate discharge property and the lithium secondary battery comprising the same. The anode active material in the present invention includes a metallic oxide which is represented as following chemical formula 1:LiWxNiaMnb-xO4(Here, 0.000<=a<0.5000, 1.4999<=b<=1.9999, 0.0001<=x<=0.0100).
