Abstract:
1. An anode active material for rechargeable lithium batteries, comprising a spinel type anode active material (Li 1.1 Mn 1.9 O 4 ) 1-x-y (MgAl 2 O 4 ) x (Co 3 O 4 ) y where 0.001≦x≦0.2 and 0.001≦y≦0.2), which is formed by substituting spinel type (MgAl 2 O 4 ) x and spinel type (Co 3 O 4 ) y into a basic spinel structure represented by (Li 1.1 Mn 1.9 O 4 ) 1-x-y .
