MIXING APPARATUS FOR MANUFACTURING POSITIVE ACTIVE MATERIAL

摘要

PURPOSE: A stirring apparatus for preparing positive active materials is provided to effectively stir an iron and lithium solution with supercritical water by mixing the solutions in a pre-mixer and changing the state of the mixed solution from gel to sol prior to the stirring process. CONSTITUTION: A stirring apparatus for preparing positive active materials includes a pre-mixer (10), at least one middle mixer (20), and a main mixer (30). The middle mixer is in connection with the rear end of the pre-mixer. An iron solution and a lithium solution are respectively injected into the pre-mixer to be stirred. Stirring beads are arranged in the middle mixer to change the state of the mixed solution from gel to sol. The mixed solution is stirred with supercritical water which is separately injected into the main mixer. [Reference numerals] (AA) Iron solution; (BB,CC) Lithium solution; (DD,EE) Supercritical water
