PURPOSE: An anode active material for a secondary lithium battery is provided to obtain an anode active material for a secondary lithium battery having an excellent high temperature cycle lift characteristics. CONSTITUTION: An anode active material for a secondary lithium battery has an equation as follows: Li1+zMn2-xMxO4+z. In the above-mentioned equation, z is equal to or larger than -0.2 and is equal to or smaller than 0.1, and x is equal to or larger than 0 and is equal to or smaller than 0.2. M is selected from La, Ce, and Bi. A lithium battery uses an anode active material which has an equation as follows:Li1+zMn2-xMxO4+z.
