LiCoO2 nano powder of a high-temperature polymorph having a small and uniform size of grains which is obtained by modifying a surface of a precursor by mixing inert soluble salt on a Li-Co acetate precursor, and by heating the surface-modified precursor is provided, and a battery manufactured by using the powder as the cathode material has very excellent chargingdischarging characteristics. A workflow management system creates and tracks the life cycle of a project for application retirement, data retirement, purge, or performance archiving. The message listener receives messages from the component applications.
