PURPOSE: A method for manufacturing LiCoO2 which is an active material is provided to have a high pyrolysis temperature and to secure an excellent temperature stability. CONSTITUTION: A method for manufacturing LiCoO2 which is active material comprises the steps of: manufacturing LiMn2O4 which is an active material for a lithium secondary battery of a formula 1 LiCoO2, which LiMn2O4 is coated on the surface in a sol and a gel state; mixing the LiMn2O4 in the sol and the gel state and the LiCoO2 in a powder state; and heating the mixture. A weight percent of the LiMn2O4 in the sol and the gel state and the LiCoO2 in the powder state are 1-5 weight percents to 95-99 weight percents. The heating process operates 600 to 700°C. |
