ANODE ACTIVE MATTER AND SECONDARY LITHIUM BATTERY USING THE SAME

摘要

PURPOSE: An anode active material for a secondary lithium battery is provided to have excellent cycle life time characteristics at charging and discharging in high rate. CONSTITUTION: An anode active material is obtained as follows. After uniformly mixing CO3O4, LiCO3, and LiF so that the mole ratio of LiCoO1.99F0.01 is obtained, the mixed resultant matter is baked under the conditions of centigrade 900°C and twenty-four hours. Then the temperature is slowly lowered until a room temperature to obtain the anode active material for a secondary lithium battery.
