NOVELTY - An anode active material contains 10 ppm or more of total iron in the active material fine particles. Iron content eluted in hydrochloric acid (HCl) aqueous solution after adding anode active material fine particles (in g) (5) to 2N HCl aqueous solution (15), stirring for 10 minutes at 25 degrees C and separating active material, is 5 ppm or less with respect to fine particles whole quantity.    USE - For electrode for lithium cell, used as power supply for drive for mobile phone, portable computer and electric vehicle (all claimed), especially for lithium primary battery, lithium secondary battery and lithium ion secondary cell for medical equipment, notebook computer, cordless phone, liquid crystal television, electric shaver, portable radio, headphone stereo cassette tape recorder, memory card, backup power supply, pacemaker, hearing aid and personal digital assistant.    ADVANTAGE - The anode active material provides battery with improved lift time and charging-and-discharging cycle characteristics.    DETAILED DESCRIPTION - An anode active material contains 10 ppm or more of total iron in the active material fine particles with respect to the whole quantity of the active material fine particles. The iron content eluted in hydrochloric acid (HCl) aqueous solution after adding anode active material fine particles (in g) (5) to 2N HCl aqueous solution (15), stirring for 10 minutes at 25 degrees C and separating the active material by filtration, is 5 ppm or less with respect to the fine particles whole quantity. INDEPENDENT CLAIMS are included for the following:    (1) an electrode for lithium cell using the anode active material;    (2) a lithium cell using the anode active material;    (3) a mobile phone, portable computer and electric vehicle, using the battery containing the anode active material as power supply for drive; and    (4) an evaluation of the anode active material for lithium cell, which involves adding anode active material fine particles to 2N HCl aqueous solution, stirring the solution and evaluating the iron content in HCl aqueous solution after separating the anode active material by filtration.
